Pole Beans

in Zone 9, this week

Pole beans are the climbing kind of green bean. Instead of staying short like bush beans, they grow as long vines that need something tall to climb, like a trellis, a teepee of poles, or a fence about 6 to 8 feet high. The reward is a long harvest: one planting keeps making beans for weeks, all the way until frost, so you pick a handful every few days instead of getting them all at once. You plant the seeds straight in the garden after the last frost, give them their support, keep them watered, and start picking in about two months. Pole beans (Phaseolus vulgaris) are the climbing form of the common snap bean: frost-tender, warm-season, nitrogen-fixing legumes grown for their tender immature pods. Unlike the self-supporting bush type, they are twining vines that need a sturdy trellis, teepee, or fence 6 to 8 feet tall to climb. That vertical habit is the payoff: a single planting flowers and sets pods progressively over many weeks, bearing more from the same ground than a bush planting and continuing right up to frost, so you pick regularly rather than facing one concentrated glut. Direct-sown into warm soil after the last frost, they reach a first pickable crop in about 60 to 70 days.

A second planting You plant pole beans once and pick for a long time. One planting keeps making beans for weeks, all the way to frost, so there is no need to replant every couple of weeks like you would with bush beans. In warm regions you may make a separate spring and a fall planting around the summer heat. The main thing is to pick often, which keeps new beans coming.Pole beans are not a succession crop the way bush beans are. A single planting climbs its support and bears progressively for many weeks, right up to frost, so you sow once per season rather than at intervals. In long-season warm regions, growers slot a separate spring and a fall sowing split by summer heat, but that is a distinct seasonal crop, not staggered succession. Keep picking every couple of days to keep the vines flowering and setting new pods.

Seed to garden

Plant pole bean seeds right where they will grow, once the soil has warmed and frost is past, and put up the trellis or poles at the same time. Beans do not like having their roots disturbed, so skip starting them indoors.Sow directly into warm soil after the last spring frost, and set the trellis, poles, or netting in place at planting so you do not disturb the roots later. Beans resent root disturbance and germinate quickly in place, so transplanting offers no advantage.

The growing journey

Stage 01 · Germination
01
Germination
Days 0-14 · current stage
Bare soil for about a week, then a bent stem pushes up through the surface, pulling two thick first leaves (called seed leaves) up with it. Beans come up fast in warm soil but rot in cold, wet ground. If you plant before the soil has warmed to about 60°F, many seeds will not come up at all.Bare soil for roughly a week, then the seedling shoulders up through the surface still bent in a hook, dragging the two thick seed leaves (cotyledons) up with it before they unfold. Emergence is fast in warm soil but stalls or rots outright in cold, wet ground. Beans sown before the soil reaches about 60°F at a 4-inch depth germinate poorly.
Wait to plant until the soil has warmed to at least 60°F. Plant about 1 inch deep in moist, well-drained soil, and put up your trellis or poles at the same time so you do not disturb the roots later. Do not keep the bed soggy.Sow only once the soil has warmed to at least 60°F at a 4-inch depth, about 1 inch deep into a moist, well-drained bed, and set the trellis, poles, or netting in place now so you do not disturb the roots later. Avoid soaking the soil, which suffocates the seed and feeds root rot fungi.
FROM PLANT · Bean seeds rot in cold, wet soil. Wait until the soil has warmed to at least 60°F before planting, because planting early just leads to rotted seed and missing plants. Beans planted into warm soil catch up fast, so there is nothing to gain by rushing.Bean seed rots in cold, wet ground. Wait until the soil is at least 60°F at a 4-inch depth before sowing, since early planting only invites poor stands and seed rot. Beans sown into warm soil quickly overtake those sown into cold soil.
FROM PLANT · Put your trellis, teepee, or netting up when you plant, not later. Pole beans climb by themselves but need a strong support, about 6 to 8 feet tall, ready and waiting. Adding it later disturbs the shallow roots.Set the trellis, teepee, or netting in place at sowing, not after the vines are up. Pole beans twine on their own but need a sturdy 6-to-8-foot support ready to climb, and installing it later disturbs shallow bean roots.
02
Seedling
Days 10-21
The two seed leaves open, then the real leaves appear, first a single pair, then the three-leaflet leaves beans are known for. The little plant soon starts to reach and twist toward its support. This young stage is when beetles can do the most damage.The cotyledons open and the first true leaves appear: a pair of single leaflets, followed by the bean's characteristic three-part (trifoliate) leaves. The plant soon begins to reach and twine toward its support. Young seedlings are the stage most vulnerable to bean leaf beetle feeding.
Keep the soil evenly moist and pull weeds early, hoeing shallowly since bean roots are near the surface. Check that the trellis or poles are ready and gently steer the first shoots onto them. You do not thin pole beans, they are planted where they will grow.Keep the bed evenly moist and weed-free; young beans compete poorly with weeds. Cultivate shallowly, since bean roots run close to the surface. Make sure the support is in place and guide the first shoots to it if needed. There is no thinning: pole beans are sown at their spacing along the support.
FROM PLANT · Pull weeds early, but weed shallowly. Young beans do not compete well with weeds, yet their roots are near the surface, so digging deep hurts the plant more than the weeds do. Pull by hand and hoe lightly near the row.Weed early and cultivate shallowly. Young beans compete poorly with weeds, but their roots run close to the surface, so deep hoeing does more harm than the weeds. Hand-pull and scuffle-hoe lightly near the row.
03
Vining and climbing
Days 18-45
Fast climbing growth as the vine winds its way up the trellis or poles, often to 6 feet or taller. Pole beans put a lot of early effort into climbing before they make many beans, so at first you will see lots of leafy vine going up rather than pods. Beans make much of their own food (nitrogen) at this stage.Rapid vining as the plant twines up its support toward its full height, often 6 feet or more. Pole beans spend real energy climbing before they set heavily, so early growth looks leafy and upward rather than fruitful. The plant is fixing much of its own nitrogen now, so vigorous but not lush, overfed growth is the goal.
Keep the watering steady and do not add fertilizer now. Beans need very little, and extra just gives you big leafy vines and later beans. Tuck any stray shoots onto the support; the vines climb on their own, but a little help early gets them going.Hold steady, even moisture and resist the urge to feed. Beans need little nitrogen, and excess now drives leafy vine growth and delays flowering. Guide wayward shoots onto the support; the vines twine on their own but a nudge helps them find the structure early.
FROM PLANT · Do not add nitrogen fertilizer now. Beans make much of their own from the air, and extra fertilizer just gives you big leafy vines and later beans. At most, feed once lightly right before they flower, and only if your soil is poor.Hold off on nitrogen. As legumes, beans fix much of their own, and extra nitrogen now drives leafy vine growth up the trellis and delays flowering. At most a single light side-dressing just before bloom, and only on poor or sandy soil.
FROM PLANT · Help the young vines find their support early. Pole beans wind their way up on their own, but steering them onto the trellis or pole in the first weeks keeps them from tangling on the ground.Guide the young shoots onto their support early. Pole beans twine counterclockwise on their own, but a nudge onto the trellis or pole in the first weeks keeps them from tangling on the ground and starts the climb clean.
04
Flowering
Days 40-62
Small white, pink, or purple flowers open along the vines. Unlike bush beans, pole beans flower a little at a time over a long stretch, so flowers and young pods appear together for weeks. This is an important time for water. If the plants dry out or it stays above about 90°F, the flowers drop without making beans, then start again once it cools.Small white, pink, or purple flowers open along the vines. Pole beans flower over a long, extended window rather than all at once, so bloom and pod set overlap and continue for weeks. This is a moisture-critical stage: water stress aborts blossoms, and sustained heat above about 90°F causes blossom drop until the weather cools.
Keep the water steady and generous, because dry soil now means fewer beans. Water the soil, not the leaves, to keep disease down. If a heat wave hits, water deeply beforehand, then wait it out, the vine will keep flowering once it cools.Keep moisture steady and ample; water stress now directly cuts the running yield. Water at the soil in the morning, not overhead, to keep the tall canopy dry. In a heat wave, water deeply ahead of it; the vine will keep reflowering as temperatures ease.
FROM PLANT · Keep the water steady and generous while the vine flowers. Flowering and pod-forming are when beans most need water, and on pole beans that lasts a long time, so letting them dry out shrinks the crop. Water the soil in the morning, not the leaves.Keep moisture steady and ample through bloom. Flowering and pod set are the moisture-critical stages, and on pole beans they run for weeks, so water stress at any point cuts the running crop. Water at the soil in the morning, not overhead.
FROM PLANT · When it stays hotter than about 90°F, beans drop their flowers. The vine gives up on flowers when it is too hot to make beans, then starts again once it cools. Since pole beans flower for a long time, the crop bounces back. Water deeply before a heat wave.Expect blossom drop in sustained heat above about 90°F. The vine aborts flowers when it is too hot to set pods, then resumes once it cools. Because pole beans flower over a long window, the crop recovers as the weather eases; water deeply ahead of a heat wave.
05
Pod set and fill
Days 50-68
Pods form where the flowers were and grow quickly, getting plumper as the beans fill inside. Because the vine keeps flowering, you will have pods of every size at once, from tiny to ready. Dry soil now makes small, tough, crooked pods and can slow down the whole run.Pods appear where flowers were and lengthen quickly, plumping as the seeds fill. Because the vine flowers continuously, you will see pods at every stage at once, from tiny to pickable. Drought here produces small, stringy pods and can stall the plant's ongoing set.
Keep the soil evenly moist all through this stage, which on pole beans lasts a long time. Start checking the pods every couple of days, because each one is ready for only a short time before it gets too old.Maintain even moisture near field capacity right through pod fill; on pole beans this stage runs for weeks. Begin checking pods every couple of days as they size up, since the pickable window for any one pod is brief.
FROM PLANT · Do not let the soil dry out while the pods are growing. Dry soil now makes small, tough, crooked beans and can slow the whole run, while steady moisture gives you plump, well-shaped ones all season.Do not let the bed dry out as pods size up. Drought during pod fill produces small, stringy pods and can stall the vine's ongoing set, while steady moisture near field capacity gives plump, well-formed ones over the whole long season.
06
Harvest
Days 58-80
Firm, crisp pods that break with a clean snap, picked before you can see the seeds bulging. Most pole beans give their first pick around 60 to 70 days and then keep producing for weeks. Picking every couple of days keeps new beans coming; leaving old pods on tells the vine to slow down.Firm, crisp pods that snap cleanly when bent, picked before the enlarging seeds bulge the pod wall. Most pole varieties reach first pick around 60 to 70 days and then keep bearing for many weeks. Regular picking every couple of days keeps the vine flowering and setting new pods; pods left to mature signal it to slow down.
Pick in the morning for the best beans, after the dew dries, snapping pods off without tearing the vine. Pick every two or three days all season long, because picking often is what keeps a pole bean producing. Do not pick when the leaves are wet, since that spreads disease.Pick in the early morning for best quality, once the dew has dried, breaking pods off cleanly without tearing the vine. Harvest every two to three days across the whole season; frequent picking is the single biggest lever on how long and heavily a pole bean bears. Do not work the vines when foliage is wet, which spreads bacterial blight.
FROM PLANT · Pick every two or three days, before the seeds swell the pods.

Beginner
Know your soil

Your soil

Identify yours

Not sure what soil you have? Grab a small handful of damp soil from your garden bed and squeeze it. If it crumbles apart easily, it's sandy. If it holds together but breaks when you poke it, it's loam (what most vegetables want). If it stays in a hard, slippery ball, it's clay.

What this crop wants

Pole beans like loose, fertile soil that drains well. If water sits on top of your bed for a long time after rain, work in some compost first to help it drain.

If your soil doesn't match

You have sandy soil

Mix 2-3 inches of compost into the top 6 inches of your bed before planting. Compost holds moisture (which sandy soil drains too fast) and adds the nutrients sandy soil tends to lack. Repeat each season. Compost breaks down over time.

You have clay soil

Mix 2-3 inches of compost AND a few inches of coarse sand or perlite into the top 6 inches of your bed. The compost feeds the plants; the sand breaks up the clay so air and water can move through. Don't add sand without compost. It can compact like concrete.

Containers and raised beds

If amending your soil sounds like too much work, or if your soil is heavy clay, full of rocks, or contaminated, build over it. A raised bed at least 12 inches deep filled with a 50/50 mix of compost and sandy loam gives you ideal growing soil with no battles. A 5-gallon container with quality potting mix does the same for one plant at a time. Both bypass your native soil entirely.

Yes, 5 gallons and up

Pole beans can grow in a big pot, but they need a tall, sturdy support they will not tip over. Use a pot at least 5 gallons, ideally 10 or more and 12 inches deep, set up a 6-foot teepee or trellis in it, plant a few seeds around the base, and keep the mix evenly moist.Pole beans grow in a large container, but they need both room and a sturdy tall support. Use a pot of at least 5 gallons, ideally 10 or more and 12 inches deep, anchored so a 6-foot teepee or trellis will not topple in wind. Plant several seeds around the support and keep the mix evenly moist.

Pot size
5 gallons and up; 10 gallons is comfortable
Drainage
Drainage holes are a must. Skip the gravel layer. Empty any saucer after watering so the pot never sits in standing water, which rots bean roots.
Watering
Pots dry out faster than garden beds, especially once the vine is large, so check the soil daily in hot weather and water when the top inch is dry.Containers dry faster than beds, and a full pole vine transpires heavily, so monitor daily in heat and water when the top inch dries.
Depth and shape
At least 12 inches deep. A deep, heavy, stable container is what matters for pole beans, unlike the wide, shallow pot that suits bush types. The pot has to anchor a 6-foot support against wind and hold enough soil to carry a large vine through a long season, so depth and weight beat surface area here.
Self-watering pot
Yes. A self-watering container suits pole beans well, smoothing out the steady moisture they want across their long bearing season.
Mix
A well-draining potting mix; avoid native garden soil, which compacts and drains poorly in containers. Blend in compost for baseline fertility; beans need little added nitrogen.
Feeding
Feeding needs stay low; a single light pre-bloom feed suffices, though a long-bearing potted vine may want one more light feeding mid-season.

Pot safety

Ask what your balcony or roof can carry

A balcony or roof can only hold so much weight. Before you set heavy pots there, ask a building architect what it can safely carry.Illinois Extension's guidance is to consult a building architect about weight limits before placing heavy pots on a balcony or rooftop garden. It gives no weight figure.

Never grow food in a container with anything toxic in it

Many kinds of containers can be used. Whatever you choose, keep anything toxic out of it, especially if you are growing food.Colorado State accepts nearly any container material but warns against using a container that holds toxic materials, especially for edible plants. Illinois adds that a vegetable container should be free of chemicals toxic to plants or people, and urges caution with treated lumber when growing food. If you cannot account for what a repurposed container once held, that alone is a reason to keep food out of it.

Secure hanging containers well

Fasten hanging baskets and window or rail boxes securely. Think about what is below them too, since they can drip on people or things underneath.Illinois Extension asks growers to secure hanging containers well and to think through the safety issues of hanging them. Placement matters too, since a hanging container can drip onto people or belongings below.

Soil chemistry

Soil pH for pole beans

Preferred
5.8 to 6.5
Tolerated
5.8 to 7

Pole beans do well in slightly acidic to neutral soil. If you have not tested your soil, a pH near 6.5 is a safe target and most garden beds are already close.A soil pH of 5.8 to 6.5 suits snap beans; they tolerate up to about neutral. A soil test is the reliable way to confirm both pH and fertility before the season starts.

Watering

When & how much
Frequency
Water regularly so the soil stays evenly moist but never soggy. Pole beans flower and fill pods for a long time, so keep the water steady all the way through the season.Regular and even through the long season, keeping soil moisture near field capacity. The need is greatest during the extended flowering and pod-fill period, which on pole beans runs for many weeks.
Amount
Water deeply enough to wet the soil about 6 inches down. Deep, less frequent watering beats a daily light sprinkle.Enough to wet the root zone roughly 6 inches down; watering deeply and less often builds a deeper root system than frequent light sprinkles.
Method
Water the soil, not the leaves, and do it in the morning. Because pole beans grow up in the air, the leaves dry off faster than on a low bush, which helps keep disease down.Water at the soil level in the morning so foliage dries quickly; trained up a trellis, the canopy dries faster than a sprawling bush, which helps limit the foliar diseases beans are prone to.
Signs of trouble
Too much water
If the soil is wet but the plants still wilt or the lower leaves turn yellow, you may be overwatering. Soggy soil rots the roots.Yellowing lower leaves, wilting despite wet soil, and stunted growth point to waterlogged roots and the onset of root rot.
Too little water
If plants dry out while flowering and filling pods, they drop their flowers and the beans come out small and tough. Keep the water steady to keep new pods coming.Drought stress during flowering and pod fill aborts blossoms and produces small, stringy pods, and it can stall the plant's ongoing pod set for the rest of the season.
Feeding rhythm

Feeding

Frequency

Type
balanced pre-plant, light nitrogen sidedress
When to start
pre-plant at sowing; one light sidedress before first bloom

Pole beans make a lot of their own food from the air, so they need little fertilizer. Mix a little balanced fertilizer into the bed before you plant, and feed once more lightly right before the plants flower. Too much fertilizer gives you big leafy vines climbing the trellis but fewer beans, and it delays flowering.Pole beans are light feeders. As legumes they fix much of their own nitrogen through root nodules, and excess nitrogen delays flowering and pushes leafy vine growth up the trellis at the expense of pods. Without a soil test, work a balanced starter into the bed before planting, then sidedress lightly just before the first bloom. Sandy beds or leaching rains can call for a second light feeding across the long bearing season.

N · P · K = 5-10-10

A balanced vegetable fertilizer like 5-10-10 works well.Pre-plant 5-10-10 if no soil test is available; sidedress a nitrogen source lightly before bloom.

Who grows well together

Companion planting

Pole beans get along with most vegetables. The classic combination is beans, corn, and squash grown together, with the beans climbing the corn. The one pairing to avoid is planting beans right next to onions or garlic. As a nitrogen-fixing legume, pole beans leave the soil better for what follows and are the classic climbing partner in the Three Sisters planting, where the beans scramble up the corn while squash covers the ground. The long-standing caution is to keep beans away from the alliums (onion, garlic), which are widely held to suppress them.

Other
Corn
The traditional Three Sisters partner; with pole beans the corn works as a living pole for the vines to climb.Corn is the classic pole bean partner in Three Sisters planting, where the corn stalk serves as a living trellis for the climbing vines. Let the corn get a good head start and use sturdy, well-rooted stalks, since vigorous pole beans can overload thin sweet corn. The beans' nitrogen fixation helps balance the bed for the heavy-feeding corn; the benefit is structural and traditional rather than a measured pest effect. Traditional
Squash
The third Sister; its broad leaves shade the soil and keep weeds down around the beans.Squash rounds out the Three Sisters trio. Its broad sprawling leaves shade the soil, hold moisture, and suppress weeds around the base of the bean supports, while the mix of heights makes it harder for pests to lock onto any one crop. This is a soil-and-space benefit; give the squash room so it does not swamp the young bean vines before they climb. Traditional
Cucumber
An easy neighbor that shares similar warm-season, full-sun needs.Cucumber and pole beans coexist comfortably: similar warm-season timing and water needs, and the beans' nitrogen fixation lightly benefits the cucumber as a moderate feeder. Trellised cucumbers can even share the vertical structure. This is a compatibility pairing rather than a strongly protective one. Well-grounded
Keep apart from
Onion Onions and other alliums are traditionally kept away from beans, which are said to grow poorly near them.Onions and beans is one of the better-grounded 'bad' pairings. Alliums release antibacterial sulfur compounds that are held to interfere with the Rhizobium bacteria on bean roots, the very bacteria the bean depends on to fix nitrogen, so bean growth tends to stall near onions. Keep them in separate parts of the bed. A useful corollary: beans grown before onions actually improve the soil for the following allium crop. Well-grounded
Garlic Like onions, garlic is a traditional bad neighbor for beans.Garlic acts on beans the same way onions do. As an allium it gives off antibacterial sulfur compounds held to disrupt the nitrogen-fixing Rhizobium bacteria on bean roots, slowing the beans down. Treat garlic and pole beans as bed-mates to keep apart, and use the bean-then-allium rotation to your advantage instead. Well-grounded

Harvest signals

When to pick

Beans are ready when the pods are firm and crisp and snap cleanly, before you can see the seeds bulging inside. Pick every two or three days all season. On pole beans, picking often is what keeps new beans coming, so do not let old pods sit on the vine.Pick when pods are firm, crisp, and snap cleanly, before the enlarging seeds bulge the pod wall. Pole beans bear over a long season, so work the vines every two to three days: regular picking keeps the plant flowering and setting new pods, while pods left to mature signal it to slow down.

Yield

What to expect

Pole beans give more from the same patch than bush beans because they grow up instead of out and keep bearing for a long time. A 10-foot row of pole beans usually gives about 8 to 12 pounds of beans over the season, versus around 5 pounds for bush beans in the same space.Pole beans out-yield bush beans from the same footprint by growing vertically and bearing over a long season. A 10-foot row of pole beans typically returns roughly 8 to 12 pounds of pods over its extended cropping period, compared with about 5 pounds for bush beans in the same space.

Instead of one big batch, pole beans give a steady supply over many weeks from a single planting, all the way to frost. That is why you do not need to replant every couple of weeks like with bush beans: one planting keeps going, as long as you pick every few days.Rather than a single burst, pole beans bear steadily over many weeks from one planting, right up to frost. That long, running harvest is why succession sowing is unnecessary: one well-tended planting keeps a household supplied, provided you pick every couple of days to keep it flowering. Pole beans are a satisfying crop for a first-year garden. They come up fast, need little fuss, and one planting keeps making beans for weeks once it starts, about 60 to 70 days from planting. The main things that affect how much you get are keeping the water steady and picking often so the vine keeps producing.Pole beans are a rewarding first-year crop: they germinate quickly, ask little, and a single planting bears for weeks once it starts, around 60 to 70 days from sowing. The main first-year lever on yield is steady moisture through the long flowering and pod-fill season, plus picking often enough to keep the vine producing.

What changes yield
Steady moisture through the long flowering and pod-fill season (the moisture-critical stages; drought aborts blossoms and stalls the running set)Frequent picking (leaving mature pods on the vine signals it to slow flowering, so picking every couple of days is the biggest lever on total yield)Temperature during bloom (sustained heat above about 90°F causes blossom drop and pauses the set until it cools)A sturdy full-height support and good sun (vertical growth on a 6-to-8-foot trellis is what lets pole beans out-yield bush beans per square foot)

Do not leave fresh beans out on the counter. They go downhill quickly, so cool them down soon after picking.Not recommended. Fresh snap beans lose quality fast at room temperature and should be cooled promptly after picking rather than held on the counter.
Fridge
Cool the beans soon after picking, then keep them in the fridge, cold and a bit humid. They stay good for about a week; left longer or warmer, they get soft spots and brown patches.Cool beans soon after harvest to shed field heat, then refrigerate cold and humid. They hold good quality for about a week; held longer or warmer, they develop watersoaked spots and browning.
Freezer
Beans freeze well for keeping longer. For the best result, freeze them within a few hours of picking, after a quick blanch in boiling water to hold their color and texture.Beans freeze well for longer storage. For best quality, freeze or can within a few hours of picking, blanching briefly first to preserve color and texture.

When something goes wrong

Common problems

Flowers fell off without making beansFlowers dropped without setting pods
01 of 04
What happened The vine flowered, but the flowers fell off without making beans, because steady heat above about 90°F stops the flowers from being pollinated and the plant drops them. Letting the plants dry out while flowering does the same thing. It is a weather problem, not a disease, and since pole beans keep flowering for a long time, the vine usually starts setting beans again once it cools.The vine flowered but the blossoms dropped instead of setting pods, because sustained heat above about 90°F interferes with pollination and the plant aborts flowers it cannot fill. Water stress during bloom has the same effect. It is a weather problem, not a disease, and because pole beans flower over a long window, the vine usually resumes setting pods once temperatures cool. Next season Plan your planting so the main flowering skips the hottest part of summer, either early enough to get going before peak heat or, in hot areas, as separate spring and fall plantings around the summer break. Keep the water steady, water deeply before a heat wave, and pick a more heat-tolerant variety like Rattlesnake if your summers are very hot.Time the planting so the heaviest bloom misses the hottest part of summer, sowing early enough to establish before peak heat or, in hot regions, running separate spring and fall sowings around the summer wall. Keep moisture steady, water deeply ahead of a heat wave, and choose more heat-tolerant varieties such as Rattlesnake where summers are reliably hot.
Seeds rotted or did not come upSeeds rotted or came up poorly
02 of 04
What happened The seeds went into soil that was too cold and wet, so they sat there instead of sprouting and rotted, or came up thin and patchy. Bean seeds do not sprout well below about 60°F, and a slow, cold start lets soil fungi and a seed-eating maggot get to the seed while it waits.The seeds were sown into soil that was too cold and wet, so they sat without germinating and rotted, or came up as a thin, patchy stand. Bean seed does not germinate well below about 60°F, and a slow, cold start invites soilborne root rot fungi and seedcorn maggot, both of which attack the lingering seed. Next season Wait until the soil has warmed to at least 60°F before planting, since there is no reward for planting beans early. Plant in well-drained soil or raised beds instead of low, wet spots, plant about 1 inch deep, and do not keep the bed soggy after planting.Wait until the soil has warmed to at least 60°F at a 4-inch depth before sowing; there is no benefit to planting early. Sow into well-drained ground or raised beds rather than low, wet spots, plant about 1 inch deep, and do not keep the bed soggy after sowing.
Big leafy vines but hardly any beansTall leafy vines but few beans
03 of 04
What happened The vines grew tall, dark, and leafy but made very few beans, usually because they got too much nitrogen. Beans make much of their own nitrogen from the air, so extra fertilizer just pushes leafy growth and delays flowering. A little early leafiness is normal, since pole beans climb before they set heavily, but if it keeps up, it is too much nitrogen.The vines grew tall, dark, and leafy up the support but set few pods, usually from too much nitrogen. As legumes, beans fix much of their own nitrogen, and extra fertilizer over-stimulates vine growth and delays flowering. Some early leafiness is normal for pole beans, which climb before they set heavily, but persistent all-vine growth points to excess nitrogen. Next season Skip the extra fertilizer. Mix in just a little balanced fertilizer or compost before planting, and at most one light feeding right before they flower, and only if your soil is poor. Let the beans make their own nitrogen, and be patient, since pole beans start making beans later than bush beans.Skip the nitrogen feeding. Work in only a little balanced fertilizer or compost before planting, and at most one light side-dressing just before bloom, and only on poor or sandy soil. Let the plant's own nitrogen fixation carry the crop, and give it time, since pole beans set later than bush beans.
Beans came out small, tough, or stringyPods small, tough, or stringy
04 of 04
What happened The beans came out small, tough, or crooked, usually because the plants dried out while flowering and filling pods, or because pods were left on too long until the swelling seeds made them woody. On pole beans this often happens when pods hidden high on the vine get missed and overripen, which also slows down new beans.The pods came out small, fibrous, or misshapen, usually from drought stress during flowering and pod fill, or from leaving pods on the vine past their tender stage, when the enlarging seeds make the pod woody. On pole beans, infrequent picking is a common cause, since overlooked pods high in the canopy overmature and also cut the vine's ongoing set. Next season Keep the water steady through the long flowering and pod-filling season, and pick every two or three days, checking the whole vine, top to bottom, while the pods are still firm and crisp. Picking often and thoroughly also keeps more beans coming.Keep moisture steady and ample through the long bloom-and-fill season, and pick every two to three days, working the whole height of the vine and harvesting pods while they are still firm, crisp, and before the seeds bulge. Frequent, thorough picking also keeps the vine producing.

Pests & diseases

Pests
Mexican bean beetle
P · 01
Symptoms Leaves that look skeletonized or lacy, with the tissue chewed away from underneath but the veins left behind. Both the spiny yellow young and the round, coppery adult beetles feed on the undersides of the leaves, and on a tall pole vine they work their way up high where they are easy to overlook. The adult is yellow to copper colored with rows of small black spots on its back.Leaves taking on a skeletonized, lacy look as tissue is chewed from the undersides, leaving the vein network behind. Both the spiny yellow larvae and the dome-shaped, coppery adults feed on leaf undersides, and on tall pole vines the damage runs high into the canopy where it is easy to miss. The adult is yellow to coppery-brown, one-quarter to one-third inch long, with eight small black spots on each wing cover. Cause The Mexican bean beetle, a leaf-eating cousin of the ladybug. The adults come out of hiding near woods in spring, feed, then lay clusters of yellow eggs under the leaves, and several generations build up over the summer.The Mexican bean beetle (Epilachna varivestis), a leaf-eating member of the ladybeetle family. Adults emerge from overwintering near woodland edges, feed, then lay clusters of yellow eggs on leaf undersides, and several generations build through the season. Organic treatment Pick off and destroy the adults, the yellow egg clusters, and the spiny young, looking under the leaves and up the vine. Done early, this works well in a home garden. Beans can lose a fair amount of leaf without losing beans, so you do not need to spray for light damage. If they get bad, an organic spray such as spinosad is labeled for bean beetles.Handpick and destroy adults, the yellow egg clusters, and the spiny larvae, checking leaf undersides up the trellis. Beans tolerate real defoliation without yield loss, about 30 percent before bloom and 15 percent during bloom and pod fill, so light feeding needs no spray. Where pressure is heavy, an organic option such as spinosad is labeled for bean beetles. Prevention Because most damage happens in July and August, planting early or making a late-summer sowing can mostly dodge it. Clear and turn under the old vines right after harvest so the beetles have nowhere to overwinter, and move your beans to a new spot each year.Since most damage falls in July and August, an early or a late-summer sowing can escape the worst of it; the varieties Wade and Black Valentine are noted as tolerant. Work crop debris into the soil promptly after harvest to remove overwintering shelter, and rotate beans away from last year's bed.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Resistant varieties

    Start at the seed rack: two varieties, Wade and Black Valentine, carry a note of tolerance for this beetle. Tolerant means the plant handles the feeding better, not that the beetle stays away, so it is worth asking for one of them if this pest turns up in your garden most years.Wade and Black Valentine are described as tolerant rather than resistant, so the gain is in absorbing feeding, not in deterring adults. A seed-order decision, settled before anything else on this list is available.

  2. Timing the planting

    Most of the chewing lands in July and August, so sowing very early, or putting in a fresh late-summer sowing, can let the crop dodge the busiest stretch. When the beetle shows up shifts by region, so check what your own extension service publishes before you move a sowing date.Damage concentrates in July and August, so moving the tender stage to either side of that window trades a treatment for a calendar decision. The window is local, so confirm it against regional guidance rather than carrying these months across climates.

  3. Crop rotation

    Give beans a different bed than the one they grew in last year. It costs nothing but a little planning, and it goes together with clearing the old vines rather than replacing that step.Move the planting off last season's bean ground. Clemson pairs rotation with prompt residue removal, so treat the two as one habit rather than as alternatives.

  4. Garden sanitation

    As soon as you have picked the last beans, pull the spent vines and work the debris into the soil so the beetles lose the cover they would otherwise shelter in over winter.Incorporating crop residue promptly after harvest strips overwintering shelter around the bed. Like any off-season step it pays out a year later, not against the beetles feeding now.

  5. Handpicking

    Check the undersides of the leaves and keep working up the trellis, because on a tall vine the feeding climbs higher than you tend to look. Take the coppery adults, the clusters of yellow eggs, and the spiny young off by hand and kill them. Started early in a home garden this carries most of the load, and light damage is not worth treating, since beans can give up a fair bit of leaf without giving up pods.Scout leaf undersides through the full canopy height and take adults, egg masses and larvae in the same pass. The published tolerance is generous, roughly 30 percent defoliation before bloom and 15 percent through bloom and pod fill, so light feeding is a scouting note rather than a treatment trigger.

  6. Spinosad

    If the beetles get ahead of you, spinosad is an organic spray labeled for bean beetles. Treat it as the step for when picking is not keeping up, and follow the label.Under heavy pressure spinosad is labeled for bean beetles and is the organic rescue here. It sits behind handpicking rather than replacing it, and label rates and intervals govern.

Aphids
P · 02
Symptoms Clusters of tiny soft-bodied insects, usually green but sometimes black or pink, packed onto the growing tips and the undersides of leaves. Heavy feeding stunts young plants and slows them down, and a sticky residue may appear. Aphids can also spread virus diseases from plant to plant.Colonies of soft-bodied, pinhead-sized insects clustered on growing tips and leaf undersides, usually green but sometimes black, yellow, or pink. Heavy feeding stunts young plants and delays maturity as the insects withdraw sap; sticky honeydew and sooty mold may follow. Cause Several kinds of aphids, most common in cool, dry weather on small plants. They multiply fast and build up thick colonies before their natural enemies catch up. Warmer weather and helpful bugs like ladybugs usually knock them back.Several aphid species (Aphis and Macrosiphum euphorbiae), most prevalent in cool, dry weather on small plants. They reproduce rapidly, building dense colonies before natural enemies catch up; warm weather and predators such as ladybugs usually bring them down. Organic treatment Blast the colonies off with a strong spray of water, or use insecticidal soap, which works on contact. Start as soon as you see them. Once it warms up, ladybugs and other helpful insects usually take care of the rest.Knock colonies off with a strong spray of water, or treat with insecticidal soap, which gives good control on contact. Begin as soon as colonies are found. Once the weather warms, ladybugs and other natural enemies generally take over. Prevention Lay down reflective mulch, which confuses aphids and cuts both their feeding and the viruses they spread, and pull nearby weeds that shelter them. Do not overfeed with fertilizer, since the soft new growth is exactly what aphids like.Lay reflective mulch, which disorients aphids and reduces both feeding and virus spread, and control nearby weeds that harbor them. Avoid overfeeding with nitrogen, which produces the soft, lush growth aphids favor.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Balanced nitrogen feeding

    Go easy on the fertilizer. Heavy feeding pushes out soft new growth, and that soft growth is exactly what aphids settle on and multiply in.Restrained nitrogen keeps growth steady instead of flushing the tender tissue that lifts aphid reproduction. Preventive, costs nothing, and it is set before the colonies arrive.

  2. Reflective mulch

    Lay a reflective mulch, a silvery sheet over the soil, while the plants are still small. It confuses aphids flying in, so there is less feeding and less of the virus they can carry from plant to plant.Reflective mulch laid early disorients incoming aphids, reducing feeding and virus spread rather than killing anything. The documented benefit is on small plants, so the window narrows as the canopy covers the sheet.

  3. Water spray

    Blast the colonies off with a strong jet of water as soon as you find them. Aphids knocked to the ground mostly do not climb back up. Do it early in the day so the leaves dry off.A forceful water spray is the first knock-back on colonies at the growing tips and leaf undersides. Start at first detection, before the colony thickens, and spray early enough in the day that foliage dries quickly.

  4. Beneficial predators

    Give the ladybugs and other helpful insects a chance before you spray anything. Once the weather warms they usually catch up with the aphids on their own, and broad sprays set them back just when they are getting to work.Aphids run ahead of their natural enemies on small plants in cool, dry weather and are generally overtaken once warmth brings resident predators up to speed. Conserving those predators is the reason to keep this ladder at its soft end.

  5. Insecticidal soap

    Where a colony is heavy, insecticidal soap gives good control, but only on what the spray actually wets. Coat the growing tips and the undersides of the leaves, and start as soon as you find the colonies rather than after they have spread.Soap works on contact with no residual, so coverage of tips and undersides decides the result and a repeat pass is often needed. Applied only where colonies sit, it leaves most of the resident predator population intact.

Two-spotted spider mite
P · 03
Symptoms Fine whitish or yellow speckling on the leaves at first, turning to a dried, bronzed look as they multiply. The clue is fine webbing on the undersides of the leaves. The mites themselves are tiny specks, easiest to see by tapping a leaf over white paper. They explode in hot, dry weather.A fine whitish or yellow stippling on the leaves at first, progressing to a bronzed, dried-out look as populations build; fine silken webbing over the leaf undersides is the giveaway. The mites are minute specks, easiest to confirm by tapping a leaf over white paper. They build explosively in hot, dry weather. Cause Two-spotted spider mites, tiny eight-legged relatives of spiders that pierce the leaf and suck out the contents. Hot, dry weather lets them build up fast, and dusty, dried-out plants are the most likely to be hit.Two-spotted spider mites (Tetranychus urticae), tiny eight-legged relatives of spiders that pierce leaf cells and suck the contents. Hot, dry conditions favor rapid buildup, and dusty, drought-stressed plants are most prone. Organic treatment Spray the undersides of the leaves with a strong jet of water to knock off the mites and webbing, and use insecticidal soap before they get too thick. Keeping the plants well watered and unstressed slows them down.Hose the undersides of leaves with a strong spray of water to dislodge mites and webbing, and treat with insecticidal soap before numbers climb too high. Keeping plants well watered and unstressed slows buildup, and ladybugs and other predators help. Prevention Keep the soil evenly moist, because dried-out plants are much more likely to get mites, and keep dust down. Check the undersides of the leaves during hot, dry weather so you catch them early.Maintain even soil moisture, since drought-stressed plants are far more mite-prone, and avoid the dusty conditions mites thrive in. Watch the undersides of leaves closely through hot, dry spells so you catch the buildup early.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Even watering

    Keep the soil evenly moist instead of letting it swing from soaked to bone dry. Plants that have been left dry are much more likely to get hit, so this is the cheapest thing you can do about mites.Drought stress is the main accelerant, so steady soil moisture is the preventive lever here. Numbers also build fastest through hot, dry spells, which is when scouting should tighten.

  2. Water spray

    Turn a strong jet of water up under the leaves to knock the mites and their webbing loose. Check undersides during hot, dry weather so you are doing this early rather than after the leaves go bronze.A forceful spray directed at leaf undersides dislodges mites and strips webbing. Repeat through the hot, dry stretch that drives buildup, since one pass only reaches what it wets.

  3. Beneficial predators

    Ladybugs and other predators feed on mites and help hold them down, so it is worth avoiding anything that would wipe them out.Resident predators contribute to holding mite numbers down, which argues for spot treatment over a broad one; the softer steps here are chosen partly to keep them working.

  4. Insecticidal soap

    If the numbers keep climbing, insecticidal soap works on contact, so aim it at the leaf undersides where the mites actually are. Use it before they get thick rather than after.Soap is a contact material with no residual: coverage of undersides and a repeat application are what decide the outcome. Applied before populations climb it does far more than a rescue attempt on an already bronzed canopy.

Bean leaf beetle
P · 04
Symptoms Large ragged holes chewed in the leaves, and on young plants, chewing around the stem near the soil that can kill seedlings. The adult is a small beetle, usually reddish or yellowish, with a few black spots down each wing cover. Early-season damage is the worst because it thins out the plants.Large, irregular holes chewed in leaves, and on young plants, girdling of stems near the soil line that can thin the stand. The adult is one-fifth to one-quarter inch long and variable in color, usually red to yellow, marked with three or four black spots along each wing cover. Damage early in the season matters most because it reduces the stand. Cause The bean leaf beetle, which is rarely a serious problem in most home gardens. The adults chew leaves and stems, and young seedlings are the most at risk.The bean leaf beetle (Cerotoma trifurcata), rarely a serious pest in most home gardens. Adults feed on foliage and stems, with seedlings the most vulnerable stage. Organic treatment Picking them off and the same steps you would use for Mexican bean beetle usually keep them in check. Beans can lose a good bit of leaf without losing beans, so light damage needs nothing. Focus on protecting young seedlings, which are the most at risk.Handpicking and the same measures used against Mexican bean beetle generally keep it in check; beans tolerate considerable leaf loss without yield penalty, so light feeding needs no action. Protect emerging seedlings, the vulnerable stage, where beetles are active. Prevention Clear away the old vines after harvest and move your beans each year so the beetles have nowhere to overwinter. A lightweight row cover over young seedlings protects them through the risky early weeks if this beetle is a problem where you are.Clear crop debris after harvest and rotate beans to deny overwintering sites. A floating row cover over emerging seedlings protects the stand through the vulnerable early weeks where the beetle is a known problem.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Crop rotation

    Move the beans to a different bed each year so the beetles do not have last year's ground to winter in.Rotating off last year's bean ground denies overwintering sites. Paired with residue removal it is the standing preventive for a beetle that is rarely serious in a home garden.

  2. Garden sanitation

    Clear the old vines and debris away after harvest, since that is the cover the beetles would otherwise use over the winter.Clearing crop residue at the end of the season removes overwintering shelter, and it is the companion move to rotation rather than a substitute for it.

  3. Floating row cover

    Where this beetle is known to be a problem locally, float a lightweight cover over the seedlings as they come up. Those first weeks are what count, because chewing around the stem near the soil can kill young plants and thin your stand.Row cover over emerging seedlings carries the stand through the vulnerable window. That stage is the one worth protecting, since early stem girdling costs plant numbers rather than just leaf area.

  4. Handpicking

    Once the plants are past the seedling stage, picking the beetles off usually keeps them in check, and the same steps you use for Mexican bean beetle apply here. Light leaf damage needs nothing, since a bean plant can shed quite a lot of leaf and still fill its pods.Handpicking, on the same routine used for Mexican bean beetle, generally holds it. Foliar tolerance is high enough that later leaf feeding rarely justifies action, so put the effort into emerging seedlings, where the loss is real.

No spray for this one. Prevention is the control.

Diseases
Bean rust
D · 01
Symptoms Rust-colored bumps, mostly on the undersides of the leaves. Badly infected leaves turn yellow, wilt, and fall off. Stems and pods can get it too. It shows up in humid weather and can hit most kinds of beans.Rust-colored, raised spots that form mainly on the lower leaf surfaces; badly infected leaves yellow, wilt, and drop. Stems and pods can be infected too. It develops under humid conditions and can affect most types of beans. Cause A fungus that survives the winter in the soil, on old plant debris, and, importantly for pole beans, on the poles and trellis used the year before. Humid weather is what lets it take hold and spread.The fungus Uromyces appendiculatus. It survives the winter in the soil, on plant debris, and, importantly for pole beans, on the poles and trellis used the previous year, a direct route back to a new crop. Humid conditions drive infection and spread. Organic treatment Pick off and throw away, do not compost, infected leaves, and give the vines room to breathe. Where rust is bad, a sulfur dust or spray gives good control if you start as the plants begin to flower and repeat every week or two, following the label.Remove and destroy infected leaves and improve airflow. Where rust has been severe, a sulfur dust or spray gives good control when begun as the plants start to bloom and repeated on a 10-to-14-day schedule; follow the label. Prevention Move your beans to a new spot if rust has been a problem, and clean or replace your poles and trellis between years, since the fungus rides over on them. Water at the base instead of overhead, keep airflow up, and pick a rust-resistant variety if it keeps coming back.Rotate beans where rust has been a problem, and because the fungus carries over on poles and trellis, clean or replace supports between seasons rather than reusing them unwashed. Grow on a support with good airflow, avoid overhead watering, and choose rust-resistant varieties where it recurs.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Resistant varieties

    If rust keeps coming back in your garden, pick a rust-resistant variety at seed-buying time. It is the least work of anything on this list.Where rust recurs, a resistant cultivar is the durable, plant-once control and the first thing to change.

  2. Crop rotation

    Move your beans to a new spot where rust has been a problem, since the fungus carries over in the soil and in old plant debris.Rotate beans out of ground with a rust history. The fungus overwinters in soil and in residue, so returning to the same bed reloads the crop from the start.

  3. Garden sanitation

    Pick off the infected leaves and get rid of them, keeping them out of the compost. Deal with the supports as well: wash them down or swap them out before you put them up again, because the fungus winters on the poles and trellis and unwashed supports bring it straight to the new crop.Strip and destroy infected foliage during the season, and treat the supports as part of the cleanup: carryover on poles and trellis is a direct route back into a new crop, and it is the piece of rust sanitation a bush planting does not have to think about.

  4. Airflow and spacing

    Train the vines so air moves through them, since rust takes hold in humid, close conditions. Room between plants and an open support both help the leaves dry.Spacing and an open support shorten leaf wetness, which is the condition humid weather supplies and the fungus needs to infect and spread.

  5. Water at the base

    Water the soil rather than the leaves. Overhead watering keeps the foliage wet, which is what rust is waiting for.Base irrigation removes the leaf wetness overhead watering adds, denying infection the humid interval it depends on.

  6. Sulfur

    Where rust has been bad, dusting or spraying with sulfur controls it well, as long as you begin at first flowering and keep it going every 10 to 14 days. Follow the label.Sulfur begun at bloom and repeated on a 10 to 14 day schedule gives good control where rust has been severe. It protects rather than cures, so the start date carries more weight than the number of applications. Follow label rates.

Anthracnose
D · 02
Symptoms Black, sunken spots about half an inch across on the pods, the clearest sign, sometimes with a pinkish ooze in wet weather. The veins on the undersides of leaves turn black, and spots show up on stems too. It shows up in cool, wet spring and fall weather, not in hot, dry summers.Black, sunken lesions about half an inch across on pods, the most prominent sign, sometimes oozing salmon-colored spores in wet weather; the veins on lower leaf surfaces turn black, and lesions appear on stems and seedling leaves. It develops in cool, wet spring and fall weather, not in hot, dry summers. Cause A fungus that rides in on infected seed and survives up to two years on old plant debris in the soil. Splashing water spreads it, and cool, wet weather is when it strikes.The fungus Colletotrichum lindemuthianum, carried on infected seed and surviving up to two years on plant debris in the soil. Splashing water spreads it, and cool, wet conditions favor infection. Organic treatment You cannot cure tissue that is already infected; pull and throw away, do not compost, affected plants and debris to slow it down. On snap beans a copper fungicide can help if you start early, but keeping seed clean and rotating does most of the work.There is no cure for infected tissue; remove and destroy affected plants and debris to limit spread. On snap beans a copper fungicide or chlorothalonil can suppress it when started early, but clean seed and rotation do most of the work. Prevention Plant certified disease-free seed and do not save seed from an infected crop. Clear away all the old plants after harvest, and do not grow beans in that spot for two to three years. Water at the base and avoid splashing soil up onto the plants.Plant certified disease-free seed and do not save seed from an infected crop. Remove all plant debris after harvest, and do not plant beans where the disease occurred for two to three years. Avoid overhead watering and splashing soil onto the plants.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Clean planting stock

    Start with certified disease-free seed, meaning seed produced and checked to be clear of this fungus, and do not save your own seed from a crop that had it. This one rides in on the seed.Seedborne inoculum starts the outbreak inside the planting rather than at its edge, which puts clean seed ahead of every in-season measure. Seed saved off an infected crop carries it straight forward.

  2. Crop rotation

    Keep beans out of that spot for two to three years. The fungus can hold on in the soil, in the remains of last year's crop, for as long as two years.A two to three year break off infected ground outlasts the debris-borne survival, reported at up to two years.

  3. Garden sanitation

    There is no fixing tissue that is already infected, so pull the affected plants and throw them out rather than composting them, and clear the debris after harvest.Infected tissue does not recover, so removal is about limiting spread now and about not carrying residue into next season. Clear the bed of debris at harvest, not just the obviously diseased plants.

  4. Water at the base

    Water at the soil line and try not to splash soil up onto the plants, since splashing water is how this one travels.Splash is the dispersal route, so base irrigation and anything that keeps soil off the lower foliage cut the number of new infections.

  5. Copper fungicide

    For snap beans, starting a copper fungicide early, before the disease has a hold, can hold it back. It will not cure what is already infected, and clean seed plus rotation still do most of the work.Copper can suppress anthracnose on snap beans when started early, acting as a protectant rather than a cure. It is a supporting step, with clean seed and rotation carrying the weight.

  6. Chlorothalonil Rescue only

    Named alongside copper as the other material that can hold anthracnose back, and only where it is started early. It suppresses rather than cures, and this crop's guidance is plain that the cultural steps above are what carries a home crop, so this sits at the far end rather than being the answer. Read its warnings before choosing it.Named with copper as a material that can suppress anthracnose where treatment starts early; the source calls cultural control the mainstay for a home crop, so this rung closes a program rather than replacing one. Suppression rather than eradication, and preventive in its timing, so a late application buys little.

Bacterial blights (common and halo)
D · 03
Symptoms Two related diseases. Halo blight makes pale greenish-yellow rings around brown spots on the leaves and shows up in cool weather. Common blight turns leaves brown so they drop fast, with no ring, and likes warm weather. Both hit stems, leaves, and pods, and both spread in rain and damp conditions.Two related diseases. Halo blight shows light greenish-yellow halos around brown leaf spots and appears in cool weather; common blight turns leaves brown so they drop quickly, with no halo, and favors warm weather. Both infect stems, leaves, and pods, and both are spread by rain and damp conditions. Cause Two kinds of bacteria, one causing common blight and one causing halo blight. Both start on infected seed, spread easily when it is wet, and survive up to two years on old plant debris in the soil.Two bacteria, Xanthomonas campestris pv. phaseoli (common blight) and Pseudomonas syringae pv. phaseolicola (halo blight). Both start on infected seed, spread readily in moisture, and survive up to two years on plant debris in the soil. Organic treatment There is no cure once plants are infected; copper sprays every 10 days can slow it down. Water at the base, not overhead, and do not touch the vines when the leaves are wet, since that carries the bacteria from plant to plant.There is no cure once plants are infected; copper fungicides applied on a 10-day schedule can slow spread. Avoid overhead watering and do not handle the vines when foliage is wet, which moves the bacteria from plant to plant. Prevention Buy new, certified seed each year instead of saving your own, since the disease travels on seed. Do not grow beans in the same spot more than once every three years, and keep out of the patch when the leaves are wet.Buy new, certified seed each year rather than saving it, since the disease is seedborne.

  1. Clean planting stock

    Start each season with fresh certified seed rather than seed you saved yourself, since both of these blights ride in on the seed. Certified means the seed was produced and checked to be free of the disease.Both pathogens are seedborne, which makes annual certified seed the highest-leverage step; seed saved off an affected crop reintroduces the bacteria into clean ground.

  2. Crop rotation

    Leave at least two seasons between bean crops on the same ground, so a bed grows beans no more often than every third year. The bacteria can last as long as two years in the remains of an old crop.A three year interval between bean crops on a bed outlasts the reported survival on debris of up to two years.

  3. Water at the base

    Water the soil, not the leaves. These bacteria move in rain and splashing water, so wet foliage is what spreads them.Overhead irrigation supplies both the splash and the leaf wetness these bacteria travel in. Base watering removes the share of it you control; rain and dew are the share you do not.

  4. Staying out of wet foliage

    Stay out of the patch while the leaves are wet from rain, dew, or watering. Brushing past wet vines carries the bacteria from plant to plant on you.Moving through a wet canopy vectors bacteria along the row in a pattern they would not reach unaided, so delay picking, tying and weeding until the foliage has dried. It lowers the rate of spread rather than stopping an infection already established.

  5. Copper fungicide

    Once a plant is infected there is no curing it, but copper sprays on a 10-day schedule can slow the spread down. Follow the label.Copper on a 10 day interval slows spread without curing infected tissue. It belongs alongside the seed and scheduling steps rather than in place of them.

Bean root rots
D · 04
Symptoms Seeds that rot before they come up, or young seedlings that come up stunted, with a soft, watery rot at the soil line. The roots die and the leaves turn yellow. It is worst in cool, wet soil that makes the seeds sit too long before sprouting.Seeds that rot before emerging, or young seedlings that come up stunted, with a watery soft rot just above or below the soil line; roots die and leaves yellow. The damage shows up most in cool, wet soils that slow germination and keep seedlings vulnerable. Cause Several fungi that live in the soil and infect seeds and young seedlings, usually Rhizoctonia, Pythium, and Fusarium. Cool, wet, poorly drained soil and damage to the roots at planting are what let them in.Several soilborne fungi that infect seeds and young seedlings, usually Rhizoctonia solani, Pythium species, and Fusarium solani. Cool, wet, poorly drained soil and root injury at planting set the stage for them. Organic treatment There is no saving seedlings that have rotted; replant once the soil is warmer and drains better. Pulling affected plants and improving drainage limits the loss. The main thing is prevention, since these fungi are already in the soil.There is no rescue for rotted seedlings; replant into warmer, better-drained conditions. Removing affected plants and improving drainage limits further loss. The real lever is prevention, since the fungi are already in the soil. Prevention Wait until the soil has warmed to about 69°F before planting, and use raised beds in well-drained ground instead of low, wet spots. Avoid damaging the roots when planting, move your beans around the garden each year, and clear away old plants after harvest.Wait until the soil has warmed to about 69°F at a 4-inch depth before sowing, and plant on raised beds in well-drained ground rather than low, wet spots. Avoid root injury at planting, rotate beans with other vegetables, and clear crop debris after harvest.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Sound sowing practice

    Wait for the soil to warm to about 69°F at 4 inches deep before you sow. Seed that sits in cold, wet ground takes a long time to come up, and that waiting stretch is when the rot gets it.Sowing once soil reaches about 69°F at a 4-inch depth shortens the time seed and seedling spend in the susceptible stage. Slow germination in cold, wet ground is the condition that gives these fungi their opening.

  2. Improve drainage

    Plant on raised beds in ground that drains, not in a low, wet spot. There is no spray for this one, so drainage is the control.Raised beds on well-drained ground remove the saturated conditions the rots depend on. Where losses have already started, better drainage plus removing the affected plants is what limits the rest.

  3. Crop rotation

    Move beans around the garden rather than growing them in the same bed year after year.Rotating beans with other vegetables is the standing recommendation here, and it sits alongside residue removal rather than ahead of the drainage and sowing decisions.

  4. Garden sanitation

    Clear the old plants away after harvest, and pull any seedlings that have rotted rather than leaving them in the bed. There is no saving them, so the choice left is whether to replant once the soil is warmer and draining better.Remove affected seedlings and clear crop residue after harvest. Rotted tissue does not recover, so the remaining decision is whether conditions have warmed and drained enough to justify a replant.

No spray for this one. Prevention is the control.

White mold (watery soft rot)
D · 05
Symptoms Small, soft, watery spots on stems, leaves, and pods that grow fast in cool, damp weather, join together, and choke off the stem. Affected pods collapse into a brown, watery mush, soon covered in white cottony mold. Crowded, overfed vines with poor airflow are the most at risk.Small, soft, watery spots on stems, leaves, and pods that enlarge fast under cool, moist conditions, run together, and girdle the stem. Affected pods collapse into a brown, watery mush, soon covered by a white cottony fungal growth. Dense, overfed vines with poor airflow are most at risk. Cause A fungus that thrives in cool, damp weather and heavy, crowded growth. Too much fertilizer makes the lush, dense vines that trap the still, humid air the mold needs.The fungus Sclerotinia sclerotiorum, favored by cool, moist conditions and heavy, dense growth. Too much fertilizer drives the lush vine growth that creates the still, humid canopy the disease needs. Organic treatment There is no home-garden spray for this one; you manage it by how you grow. Pull and throw away, do not compost, infected plants, and open up the airflow. Training the vines up their support and thinning crowded growth helps the leaves dry out faster.There is no recommended chemical control for the home garden; management is cultural. Remove and destroy infected plants, and improve air circulation. Training vines up a support and thinning crowded growth helps the canopy dry. Prevention Give the vines room for air to move instead of crowding them, and go easy on fertilizer, since too much makes the heavy growth the mold likes. Growing up a trellis actually helps, keeping the leaves off the wet ground. Water at the base and avoid keeping the plants wet and packed together.Give plants good airflow rather than crowding, and go easy on fertilizer, since excess nitrogen feeds the heavy vine growth that favors the disease. Vertical growth on a trellis is an advantage here, keeping the canopy off the ground; avoid overhead watering and the wet, still conditions the fungus needs.
The control ladder

The ladder troubleshoots from the gentlest solution to the strongest. Start with the gentlest option and only move on when and if it doesn't work.

  1. Airflow and spacing

    Give the vines room and keep air moving through them. Tie them up their support and thin out any crowding, which lets the leaves dry faster, and growing upward is an advantage here because it keeps the canopy up off wet ground.Open spacing, vertical training and thinning a crowded canopy shorten the leaf wetness this fungus needs. Vertical growth is a genuine advantage for pole types, lifting the canopy clear of the soil surface.

  2. Balanced nitrogen feeding

    Go easy on fertilizer. Too much of it drives the heavy, crowded vine growth that traps still, damp air, and that is the setting this mold needs.Excess nitrogen builds the dense canopy that holds moisture and stills the air. The lever here is canopy architecture rather than tissue chemistry, so modest feeding is a disease decision as much as a nutrition one.

  3. Water at the base

    Water at the base rather than overhead, so you are not adding wet leaves to a canopy that is already damp and packed together.Base irrigation avoids adding surface wetness to a canopy that is already slow to dry under the cool, moist conditions the fungus favors.

  4. Garden sanitation

    There is no chemical control recommended for home gardens here, so how you grow the crop is the control. Pull the infected plants and throw them out rather than composting them.With no chemical control recommended for the home garden, removing infected plants is the in-season step; destroy the tissue rather than composting it, and pair it with opening the canopy back up.

No spray for this one. Prevention is the control.

Where to plant next year

Crop rotation

Move your beans to a new spot each year, on about a three-year rotation, and clean or swap out the poles and trellis between seasons. Because beans feed the soil with nitrogen, whatever you plant there next will benefit.Rotate beans on a roughly three-year cycle, and clean or replace poles and trellis between seasons since rust and blights persist on them. Their nitrogen-fixing habit makes beans a good predecessor for nitrogen-hungry crops.

Family
Fabaceae (legume)
Years between
3 years
in the same bed
Avoid following
Do not plant beans in the same spot two years running. Diseases build up in the soil and can hit the next bean crop, and they also ride over on old poles and trellis, so clean or replace those too.Avoid following beans with beans or other legumes in the same bed; rotate to break the soil-borne disease cycle beans are prone to. Because rust and blights carry over on poles and trellis, clean or replace those supports between seasons as well as moving the bed.
Plant after
Beans are an excellent crop to grow before a heavy feeder. As a legume they fix nitrogen and leave the soil in better shape for a following crop such as a leafy green or corn.

When plant taps you on the shoulder

The plant app sends a timely reminder at every critical moment of your pole beans season. The wording adjusts to whichever you pick: beginner or seasoned. Here are three you'll see in Zone 9.

Last frost arrives
Time to plant pole beans Time to sow pole beans
Plant pole beans right in the garden after the last spring frost, once the soil has warmed to at least 60°F. Plant about 1 inch deep, and put up your trellis or teepee of poles at the same time so you do not disturb the roots later. Direct-sow pole beans after the last spring frost, once the soil has warmed to at least 60°F at a 4-inch depth. Sow about 1 inch deep into a moist, well-drained bed, and set your trellis, poles, or netting in place at planting so you do not disturb the roots later.

Most pole beans are ready for a first pick around 60 to 70 days. Start checking and pick firm, crisp pods that snap cleanly, before the seeds bulge through. From now on the vine keeps making beans for weeks. Most pole beans reach first pick around 60 to 70 days. Begin checking and pick firm, crisp pods that snap cleanly, before the seeds bulge.

10 weeks after planting
Keep picking to keep beans coming Keep picking to keep them producing
Pick your pole beans every two or three days all season. Picking often is what keeps a pole bean making more beans, so do not let old pods sit on the vine. You do not need to plant again, one planting keeps going until frost. Pick pole beans every two to three days all season. Regular picking is what keeps the vine flowering and setting new pods; pods left to mature signal it to slow down. There is no need to succession-sow, one planting bears until frost.
