Green Beans (Bush)

in Zone 9, this week

Bush beans are one of the easiest vegetables to grow and a great first crop. They are small, tidy plants that do not need staking, and they go from seed to harvest in about two months. You plant the seeds straight in the garden after the last frost, keep them watered, and start picking. Because a patch produces a big batch all at once, planting a new short row every couple of weeks keeps fresh beans on the table all summer. Bush snap beans (Phaseolus vulgaris) are a fast, frost-tender warm-season legume grown for their tender immature pods. Compact and self-supporting, they crop heavily over a concentrated two-to-three-week window, which makes succession sowing the key to a steady supply. Direct-sown into warm soil after the last frost, they fix their own nitrogen, ask little of the gardener, and reach a pickable crop in about 50 to 60 days.

Succession planting

A row of bush beans gives you a lot of beans all at once, then slows down. To keep beans coming, plant a new short row every couple of weeks through the summer. Stop planting about two months before your first fall frost so the last batch has time to finish.Bush beans crop heavily over a short two-to-three-week window, then taper. Sow a fresh short row every two weeks from the last spring frost until about two months before your first fall frost, and you will keep fresh beans coming all season instead of facing one big glut.

Seed to garden

Plant bean seeds right where they will grow, once the soil has warmed and frost is past. Beans do not like having their roots disturbed, so skip starting them indoors.Sow directly into warm soil after the last spring frost. Beans resent root disturbance and germinate quickly in place, so transplanting offers no advantage and risks setting plants back.

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 planted before the soil reaches about 60°F at a 4-inch depth germinate poorly, and a slow start invites seedcorn maggot and seed rot.
Wait to plant until the soil has warmed to at least 60°F. There is no reward for planting early with beans, only rotted seed. Plant about 1 inch deep in moist, well-drained soil, and do not keep the bed soggy.Sow only once the soil has warmed to at least 60°F at a 4-inch depth; there is no advantage to planting early, and every advantage to waiting. Sow about 1 inch deep into a moist, well-drained bed and avoid soaking the soil, which suffocates the germinating 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, seed rot, and seedcorn maggot. There is no head start to be had: beans sown into warm soil quickly overtake those sown into cold soil.
FROM PLANT · Plant bean seeds right in the garden instead of starting them inside. Beans do not like having their roots disturbed and sprout quickly anyway, so there is no benefit to transplanting. Plant about 1 inch deep in moist, well-drained soil.Sow beans where they will grow rather than starting them indoors. Beans resent root disturbance and germinate fast in place, so transplanting offers no advantage and sets plants back. Sow about 1 inch deep into a moist, well-drained bed.
02
Seedling
Days 10-21
The two seed leaves open, then the real leaves appear, first a single pair, then the three-leaflet leaves that beans are known for. Once they are up and the weather is warm, they grow fast. This young stage is when beetles can do the most damage to the little plants.The cotyledons open and the first true leaves appear: a pair of single leaflets, followed by the bean's characteristic three-part (trifoliate) leaves. Growth is quick once the plant is up and the weather is warm. Young seedlings are the stage most vulnerable to bean leaf beetle feeding, which can thin a stand.
Keep the soil evenly moist and pull weeds early, because small beans do not compete well with them. Weed and hoe shallowly, since bean roots are close to the surface. You do not need to thin bush 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 and are easily damaged. There is no thinning to do: bush beans are sown at their final spacing and are not thinned.
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, especially in the first six weeks.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, especially in the first six weeks.
03
Leafy growth
Days 21-38
The plant grows leafier and fills out to its full size, usually about two feet tall, building up before it flowers. Beans make much of their own food (nitrogen) at this stage. You want healthy green growth, not huge dark leafy plants, which often mean too much fertilizer and fewer beans later.Steady leafy growth as the bush fills out to its full height of about two feet and builds the canopy that will support flowering. The plant is fixing much of its own nitrogen now through root nodules, so vigorous but not lush, overfed growth is the goal. Overly dark, leafy plants with little branching signal excess nitrogen and forecast a poor pod set.
Keep the watering steady and do not add fertilizer now. Beans need very little, and extra fertilizer gives you big leafy plants but fewer beans. One light feeding right before they flower is all they need, and only in poor soil.Hold steady, even moisture and resist the urge to feed. Beans need little nitrogen, and adding more now pushes leafy growth at the expense of flowers and pods. A single light side-dressing before bloom is plenty, and only on poor or sandy soil.
FROM PLANT · Do not add nitrogen fertilizer now. Beans make much of their own from the air through their roots, and extra fertilizer just gives you big leafy plants with fewer 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 through root nodules, and extra nitrogen now drives leafy growth at the expense of flowers and pods. At most, a single light side-dressing just before bloom, and only on poor or sandy soil.
04
Flowering
Days 35-50
Small white, pink, or purple flowers open all over the plant. Bush beans flower in a short burst, so most of your crop is decided in a week or two. This is the most important time for water. If the plants dry out or the weather stays above about 90°F, the flowers drop without making beans. They start setting beans again once it cools off.Small white, pink, or purple flowers open across the bush. Bush beans flower over a concentrated window, so most of the crop is set here within a week or two. This is the moisture-critical stage: water stress now aborts blossoms, and sustained heat above about 90°F causes blossom drop, especially in varieties like Blue Lake 274. Pod set resumes once the weather cools.
Keep the water steady and generous while the plants are flowering, because dry soil now means fewer beans. Water the soil, not the leaves, to avoid spreading disease. If a heat wave hits, water deeply the day before, but mostly just wait it out, the plants will flower again when it cools.Keep moisture steady and ample through bloom; this is where water stress directly cuts yield. Avoid overhead watering, which spreads disease onto the now-dense canopy. In a heat wave, water deeply the day before and consider temporary afternoon shade, but mostly the plant will recover and reflower when temperatures ease.
FROM PLANT · Keep the water steady and generous while the plants flower. Flowering and pod-forming are the times beans most need water, and letting them dry out now makes the flowers drop and the crop shrink. Water the soil in the morning, not the leaves, to keep disease down.Keep moisture steady and ample through bloom. Flowering and pod set are the moisture-critical stages, and water stress now aborts blossoms and directly cuts the crop. Water at the soil in the morning, not overhead, to keep the dense canopy dry and limit disease.
FROM PLANT · When it stays hotter than about 90°F, beans drop their flowers, especially varieties like Blue Lake 274. The plant gives up on flowers when it is too hot to make beans, then starts again once it cools. Water deeply before a heat wave, but mostly just wait, the plants will flower again.Expect blossom drop in sustained heat above about 90°F, especially in varieties like Blue Lake 274. The plant aborts flowers when it is too hot to set pods, then resumes once the weather cools. Water deeply ahead of a heat wave, but mostly let the plant recover and reflower.
05
Pod set and fill
Days 42-55
Little pods form where the flowers were and grow quickly, getting plumper as the beans fill inside. Along with flowering, this is when steady water matters most: dry soil now makes small, tough, crooked pods. Pods can go from just right to too old in only a few days.Tiny pods appear where flowers were and lengthen quickly, plumping as the seeds inside begin to fill. This and flowering are the two moisture-critical stages; drought here produces small, stringy, misshapen pods. Pods can go from pickable to overmature in a few days, so the window is short.
Keep the soil evenly moist all through this stage, it is what all the steady watering was for. Start checking the pods every day as they grow, because they are ready for only a short time before they get too old.Maintain even moisture near field capacity right through pod fill; this is the payoff stage for steady watering. Begin checking pods daily as they size up, since the pickable window is brief and the first pods reach harvest size quickly.
FROM PLANT · Do not let the soil dry out while the pods are growing. Dry soil now makes small, tough, crooked beans, while steady moisture gives you plump, well-shaped ones. This is what all that careful watering was building toward.Do not let the bed dry out as pods size up. Drought during pod fill produces small, stringy, misshapen pods, while steady moisture near field capacity gives plump, well-formed ones. This is the payoff stage for all the even watering that came before.
06
Harvest
Days 50-65
Firm, crisp pods that break with a clean snap, picked before you can see the seeds bulging through the pod. Most bush beans are ready around 50 to 60 days. They produce a big batch over two to three weeks, so pick every couple of days to keep them coming and to catch the beans while they are tender.Firm, crisp pods that snap cleanly when bent, picked before the enlarging seeds bulge the pod wall. Most bush varieties reach this around 50 to 60 days. Because bush beans crop over a concentrated two-to-three-week window, the plants come on heavily and then taper; regular picking every couple of days keeps them producing and catches pods at peak tenderness.
Pick in the morning for the best beans, snapping the pod off above its little cap so you do not tear the stem. Pick every two or three days, because leaving old pods on the plant tells it to stop making more. Do not pick when the leaves are wet, since that spreads disease.Pick in the early morning for best quality, breaking pods off above the cap so the brittle stems are not torn. Harvest every two to three days; leaving mature pods on the plant signals it to stop flowering and ends the crop early. Do not pick when foliage is wet, which spreads bacterial blight.
FROM PLANT · Pick every two or three days, before the seeds swell the pods. Bush beans give a big crop over a short time, and leaving old pods on the plant tells it to quit making more. Picking often keeps the beans coming and catches them while they are tender.Pick every two to three days, before the seeds bulge the pod. Bush beans crop heavily over a short window, and leaving mature pods on the plant signals it to stop flowering, ending the crop early. Frequent picking keeps the plant producing and catches pods at peak tenderness.
FROM PLANT · Pick in the morning for the best beans, but wait until the dew has dried off the plants. Touching wet bean plants spreads disease through your patch, so let the leaves dry before you start picking.Pick in the early morning for best quality, but only once the dew has dried. Handling wet bean plants spreads bacterial blight through the planting, so wait for the foliage to dry before working down the rows.

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

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.

A pot of at least 5 gallons and 8 inches deep, planted with several seeds for a worthwhile pick, performs well with even moisture.

Mature size

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, so check the soil daily in hot weather and water when the top inch is dry.Containers dry faster than beds; monitor daily in heat and water when the top inch dries.
Depth and shape
At least 8 inches deep. A wide container suits bush beans better than a deep, narrow one. Their roots are shallow and run near the surface, and they crop best with several plants grown together, so surface area matters more than depth. A broad pot lets you space several seeds across the top for a worthwhile pick from one container.
Self-watering pot
Yes. A self-watering container suits beans well, smoothing out the steady moisture they want through pod fill.
Mix

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 green beans (bush)

Preferred
5.8 to 6.5
Tolerated
5.8 to 7

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. 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. Pay closest attention while the plants are flowering and the pods are filling out.Regular and even through the season, keeping soil moisture near field capacity. The need peaks during flowering and pod sizing.
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 so the plants dry off during the day. Wet leaves overnight can spread disease.Water at the soil level in the morning so foliage dries before evening; this limits 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, they drop their flowers and the beans come out small and tough. Keep the water steady at that stage.Drought stress during and after flowering aborts blossoms and produces small, stringy pods.
Feeding rhythm

Feeding

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

Beans make a lot of their own food from the air, so they do not need much fertilizer. Mix a little balanced fertilizer into the bed before you plant, and feed once more right before the plants flower. Too much fertilizer gives you big leafy plants but fewer beans.Snap beans are moderate, light feeders. As legumes they fix much of their own nitrogen, so heavy nitrogen pushes leafy growth at the expense of pods. Without a soil test, work in a balanced starter before planting, then sidedress once just before the first bloom. Sandy beds or leaching rains can call for a second light sidedress.

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 before bloom.

Try 5-10-10 pre-plant
Who grows well together

Companion planting

Beans get along with most vegetables. The classic trio is beans with corn and squash. The one pairing to avoid is planting beans right next to onions or garlic. As a nitrogen-fixing legume, beans leave the soil better for what follows and pair traditionally with corn and squash in the Three Sisters planting. 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; corn gives a little structure and the planting has been grown together for generations.Corn is the classic bean partner in three-sisters planting. With pole beans the corn is a living trellis; with bush beans the relationship is looser, mostly foliage diversity and efficient use of the same bed. The benefit is structural and space-based rather than a measured pest effect, and since corn is a heavy feeder, the beans' nitrogen fixation helps balance the bed over the season. 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 beans, while the varied foliage heights of the planting make 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 bush beans, which sit lower than pole beans would. Traditional
Cucumber
A common, easy neighbor that shares similar warm-season, full-sun needs.Cucumber and bush beans coexist comfortably: similar warm-season timing and water needs, complementary growth habits, and the beans' nitrogen fixation lightly benefits the cucumber as a moderate feeder. The added foliage diversity is a modest plus for pest disruption. This is a compatibility pairing rather than a strongly protective one, so expect easy cohabitation more than active pest control. 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 interfere with the Rhizobium bacteria living 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 or peas 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 that disrupt the nitrogen-fixing Rhizobium bacteria on bean roots, slowing the beans down. Treat garlic and bush beans as bed-mates to keep apart, and use the bean-then-allium rotation to your advantage instead. Well-grounded

When to pick

Beans are ready when the pods are firm and crisp and break with a clean snap, before you can see the seeds bulging inside. Pick every few days to keep more beans coming.Pick when pods are firm, crisp, and snap cleanly, before the enlarging seeds bulge the pod. Harvesting every couple of days keeps plants producing and catches pods at peak tenderness.

Yield

What to expect

Each bush bean plant gives only a modest amount, which is why they are grown in short rows or patches rather than one at a time. A 10-foot row usually gives about 5 to 10 pounds of beans over its main picking weeks.Bush beans yield modestly per plant, which is why they are grown in short rows or blocks rather than singly. A 10-foot row of bush beans typically returns about 5 to 10 pounds of pods over its concentrated cropping window.

Bush beans give most of their crop in a short two-to-three-week burst, then slow down. That is why planting a new short row every couple of weeks keeps beans coming steadily instead of arriving all at once.Bush beans crop heavily over a concentrated two-to-three-week window, then taper. Most of a row's yield comes in that burst, which is why succession sowing every couple of weeks is the way to keep a steady supply rather than facing one large glut. Bush beans are one of the most reliable crops for a first-year garden. They come up fast, need little fuss, and give a real harvest in about 50 to 60 days. Even a short row should give you a good pick, and the main thing that affects how much you get is keeping the water steady while they flower and form pods.Bush beans are among the most dependable first-year crops: they germinate quickly, ask little, and produce a real harvest in about 50 to 60 days. A first-year grower can reasonably expect a solid pick from even a short row, with steady moisture through flowering and pod fill being the main lever on yield.

Storing your harvest

Room temp
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 right after picking, then keep them in the fridge. They stay good for about a week when kept cold and damp; left longer or warmer, they get soft spots and brown patches.Cool beans immediately after harvest to shed field heat, then refrigerate. They hold good quality for about a week when kept cold and humid, near 45°F at high humidity; 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.

Common problems

Flowers fell off without making beansFlowers dropped without setting pods
01 of 04
What happened The plant 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. Some varieties, like Blue Lake 274, are hit harder. Letting the plants dry out while flowering does the same thing. It is a weather problem, not a disease, and the plant usually starts setting beans again once it cools off.The plant 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. Some varieties, such as Blue Lake 274, are especially prone. Water stress during bloom has the same effect. It is a weather problem, not a disease, and the plant usually resumes setting pods once temperatures cool. Next season Plan your planting so the flowering time skips the hottest part of summer, either early enough to finish before peak heat or as a late-summer planting for a fall crop. Keep the water steady while they flower, water deeply before a heat wave, and pick more heat-tolerant varieties if your summers are very hot.Time plantings so bloom misses the hottest part of summer, sowing early enough to crop before peak heat or as a late-summer succession for a fall crop.

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 plants but hardly any beansBig leafy plants but few beans
03 of 04
What happened The plants grew big, dark, and leafy but made very few beans, because they got too much nitrogen. Beans make much of their own nitrogen from the air, so extra fertilizer just pushes leafy growth, delays flowering, and gives you fewer beans.The plants grew large and dark and leafy but set few pods, because they were given too much nitrogen. As legumes, beans fix much of their own nitrogen, and extra fertilizer over-stimulates leaf growth, delays flowering, and reduces pod set. 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.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.
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, which is the time they most need water, or because the pods were left on too long, until the swelling seeds made them woody. Both are easy to fix.The pods came out small, fibrous, or misshapen, usually from drought stress during and after flowering, which is the moisture-critical window, or from leaving pods on the plant past their tender stage, when the enlarging seeds make the pod woody. Both are easy to prevent. Next season Keep the water steady from the first flowers through pod-filling, and pick every two or three days while the pods are still firm and crisp, before you can see the seeds bulging. Picking often also keeps more beans coming.Keep moisture steady and ample from first flower through pod fill, and pick every two to three days, harvesting pods while they are still firm, crisp, and before the seeds bulge. Frequent picking also keeps the plant producing.

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 (larvae) and the round, coppery adult beetles feed on the undersides of the leaves, and when there are a lot of them they also chew stems and pods. 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 away from the undersides, leaving the network of veins behind. Both the spiny yellow larvae and the dome-shaped, coppery adults feed on the leaf undersides, and when abundant they move on to stems and pods. The adult is yellow to coppery-brown 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. It is worst in the Mid-Atlantic and southern Appalachian areas and is rarely a problem on the West Coast.The Mexican bean beetle (Epilachna varivestis), a leaf-eating member of the ladybeetle family. Adults emerge from overwintering near woodland edges, feed for a week or two, then lay clusters of yellow eggs on leaf undersides; there are about three generations a year, so populations build through the season. It is most damaging in the Mid-Atlantic and southern Appalachian regions and is largely absent from the Pacific Coast states. Organic treatment Pick off and destroy the adults, the yellow egg clusters, and the spiny young, looking under the leaves. 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, and a tiny helper wasp is sold to control them.Handpick and destroy adults, the yellow egg clusters, and the spiny larvae, checking leaf undersides; this is effective in a home patch caught early. Beans tolerate real defoliation without yield loss (about 30 percent before bloom, 15 percent during bloom and pod fill), so light feeding needs no spray. Where pressure is heavy, an organic option such as spinosad or a pyrethrin is labeled for bean beetles; the parasitic wasp Pediobius foveolatus is sold for biological control. Prevention Because most damage happens in July and August, fast-maturing beans planted very early or in late summer can mostly dodge it. The varieties Wade and Black Valentine hold up better. Clear and turn under the old plants 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, quick-maturing varieties sown very early or in late summer can largely escape it. The varieties Wade and Black Valentine are 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

    Wade and Black Valentine are listed as tolerant varieties, which means they hold up better under feeding, not that they go untouched. If this beetle turns up most years where you garden, that choice is made at seed-buying time.Wade and Black Valentine carry documented tolerance rather than immunity; a plant-once decision worth making where Mid-Atlantic or southern Appalachian pressure is routine.

  2. Timing the planting

    Most of the chewing lands in July and August, so a fast-maturing bush bean sown very early, or a second sowing made in late summer, can largely miss the worst of it.Damage concentrates in July and August as successive generations stack up, so quick-maturing varieties sown well ahead of that window, or a late-summer sowing behind it, sidestep much of the pressure.

  3. Crop rotation

    Move beans to a different bed rather than replanting where they grew last season.Rotation off last year's bean ground is paired with prompt debris removal in the standing prevention advice; treat the two as one habit rather than as alternatives.

  4. Garden sanitation

    Right after your last picking, pull the spent plants and work them into the soil so the beetles lose the leftover cover they would shelter in over winter.Prompt incorporation of crop debris after harvest strips the overwintering shelter the bed offers; adults also winter near woodland edges, which is why this sits alongside rotation and sowing time rather than replacing them.

  5. Handpicking

    Turn the leaves over and take the coppery adults, the spiny yellow young (called larvae), and the clusters of yellow eggs in one pass. Caught early, this works well in a home-sized patch. Beans shrug off a fair amount of chewing, so light feeding is not worth chasing.Scout leaf undersides and take adults, egg masses, and larvae in the same pass; effective in a home patch when started early. Beans tolerate roughly 30 percent defoliation before bloom and 15 percent through bloom and pod fill, so light feeding sits below any treatment threshold.

  6. Buying and releasing natural enemies

    A small parasitic wasp, Pediobius foveolatus, is sold as a biological control for bean beetles, meaning it is a living helper you buy and release rather than a spray.Pediobius foveolatus is commercially available against this beetle; a purchased release, so it fits an active infestation on a planting big enough to justify the cost, with handpicking already in place.

  7. Spinosad

    Only where the beetles get heavy despite the steps above. Spinosad is an organic spray labeled for bean beetles. Follow the label, and skip it for light feeding, since beans can lose leaf without losing pods.Reserve for heavy pressure: spinosad is labeled for bean beetles where timing and handpicking have not held. Weigh it against the defoliation tolerance before treating.

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 large volumes of sap; a sticky honeydew and sooty mold may follow. Aphids also transmit the mosaic viruses of beans. 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), 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. Too much nitrogen pushes out soft, lush growth, which is the tissue aphids favor.Restrained nitrogen keeps growth from turning soft, denying colonies the flush they build on fastest.

  2. Reflective mulch

    Lay reflective mulch, a shiny surface over the soil, while the plants are still small. It confuses aphids arriving to feed and cuts down on the mosaic viruses they carry from plant to plant.Reflective mulch disorients incoming aphids, reducing both feeding and spread of the bean mosaic viruses; laid early while the canopy is still open enough for it to work.

  3. Water spray

    A strong jet from the hose knocks the colonies off the growing tips and leaf undersides. Do it as soon as you find them, before the clusters thicken.A forceful water spray dislodges colonies without touching natural enemies; start at first detection, since reproduction outruns the predators early in the season.

  4. Beneficial predators

    Ladybugs and other helpful insects usually bring aphids down once the weather warms, so give them a chance before reaching for anything stronger.Resident predators generally overtake aphid colonies as temperatures rise; conservation is the default control here, with sprays held behind it.

  5. Insecticidal soap

    If colonies keep building, insecticidal soap works on contact, so spray it straight onto the aphids under the leaves. Start when you first see colonies rather than waiting.Insecticidal soap gives good contact control where coverage reaches leaf undersides; begin at first colonies, ahead of the honeydew and sooty mold that follow heavy feeding.

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 on the undersides, easiest to confirm by tapping a leaf over white paper. They build explosively in hot, dry weather, completing a generation in as few as eight days. 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, and helpful bugs pitch in.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 swinging between soaked and bone dry. Drought-stressed plants are far more likely to be hit, so steady watering is the first thing to fix.Even soil moisture removes the drought stress that predisposes plants to rapid buildup; the standing preventive through hot, dry spells.

  2. Water spray

    Aim a strong spray of water at the undersides of the leaves to knock the mites and their webbing off. Check those undersides through hot, dry weather so you catch the buildup while numbers are still low.Hosing leaf undersides dislodges mites and strips webbing; repeat it, since a generation can close in as few as eight days in heat.

  3. Beneficial predators

    Ladybugs and other predators feed on mites and help hold them down, so leave them room to work before you spray.Resident predators contribute suppression alongside the physical knock-back, which is why they sit ahead of any spray in the sequence.

  4. Insecticidal soap

    Insecticidal soap works only where it lands, so coat the undersides of the leaves. Use it before the mites get thick, since it is much harder once they explode in hot weather.Apply before numbers climb, with coverage on the undersides where colonies sit; in hot, dry weather population growth can outpace a late application.

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 running down each wing cover. The color varies a lot. 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 small and variable in color, usually reddish or yellowish, marked with a handful of black spots set along each wing cover near where the two covers meet. 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 plants 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

    Plant beans in a new spot each year so the beetles are denied the place they would overwinter.Rotating beans off the previous bed denies overwintering sites, paired with post-harvest debris removal.

  2. Garden sanitation

    Clear the finished plants away after your last picking, since leftover debris is where the beetles get through the winter.Post-harvest residue removal takes out the overwintering shelter; the same pass already run for Mexican bean beetle covers it.

  3. Floating row cover

    Where this beetle is a known problem, cover the seedlings with a lightweight fabric row cover as they come up. The early weeks are what matter, because chewing around the stem near the soil can kill young plants and thin the stand.Where this beetle is locally established, covering the row until plants are past the girdling-susceptible stage keeps the stand intact; it is that stand loss, not the leaf holes, that costs yield.

  4. Handpicking

    Pick the beetles off as you see them. A fair amount of chewed leaf on an established plant costs you no pods, so ragged holes there usually need nothing. Put your attention on the seedlings.Handpicking, with the Mexican bean beetle measures already running, generally holds this one; foliar feeding on established plants falls inside the crop's defoliation tolerance, so the seedling stage is where intervention pays.

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 underneath the leaves; 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 even on stakes used the year before. Humid weather is what lets it take hold and spread.The fungus Uromyces appendiculatus. It carries over from one season to the next in the soil and on leftover plant debris, and can persist on stakes or poles reused from a previous crop. Humid conditions drive infection and spread. Organic treatment Pick off and throw away (do not compost) infected leaves and give the plants 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, since the fungus carries over on old plants and stakes, and clean or replace stakes between years. Water at the base instead of overhead, give plants room, and pick a rust-resistant variety if it keeps coming back.Rotate beans where rust has been a problem, since the fungus carries over on debris and stakes; clean or replace stakes between seasons. Avoid overhead watering and space plants for airflow, 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 when you buy seed.Rust-resistant cultivars are the standing answer where the disease recurs, chosen at purchase rather than fought in season.

  2. Crop rotation

    Where rust has shown up before, put beans on new ground. The fungus rides through winter in the soil and in leftover debris.Rotate off ground with a rust history; the fungus carries season to season in soil and residue, so a repeat planting meets last year's carryover.

  3. Water at the base

    Water the soil rather than the leaves. Rust develops in humid conditions, so anything that keeps the foliage wet longer works in its favor.Base watering avoids the overhead wetting that feeds infection; humidity is the named driver for this one.

  4. Airflow and spacing

    Give the plants enough room that air moves through them and the leaves dry off. Crowded beans hold humidity, which is what rust needs.Spacing for airflow shortens the humid periods that drive infection; set at planting rather than reached for as a rescue.

  5. Garden sanitation

    Pick off and destroy the leaves carrying rust bumps rather than composting them, clear the old plants at season's end, and clean or replace any stakes or supports you reuse, since the fungus can persist on them.Remove infected foliage in season and residue at the end of it; carryover on stakes or supports reused from a previous crop is documented, so clean or replace them between seasons.

  6. Sulfur

    Where rust has run severe, sulfur dust or spray gives good control, but begin at first flowers and reapply about every 10 to 14 days. Follow the label.Sulfur begun at the start of bloom and held to a 10 to 14 day interval is the option where rust has run severe; it is a scheduled program, so the interval is the part that carries it.

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; cultural control is the mainstay for a home crop. 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. This fungus travels in the seed itself, so seed held back from a crop that had anthracnose brings it straight back.The pathogen is seedborne, so certified clean seed is the entry point; saved seed off an affected crop reintroduces it directly.

  2. Crop rotation

    Keep beans out of that spot for two to three years. The fungus can live on old plant debris in the soil for up to two years.A two to three year break off affected ground covers the up-to-two-year survival on residue.

  3. Garden sanitation

    Pull and destroy affected plants rather than composting them, and clear all the old plants after harvest. Tissue that is already infected cannot be cured, so removal is about slowing the spread.There is no cure for infected tissue, so removing affected plants and clearing residue after harvest is the working control.

  4. Water at the base

    Water at the soil line, and keep soil from splashing onto the leaves. Splashing water is how this fungus gets around.Splash dispersal is the in-season spread mechanism, so base watering and keeping soil off the foliage matter most through the cool, wet spells that favor it.

  5. Copper fungicide

    Copper fungicide can hold it back on snap beans if you begin early, though clean seed and rotation do most of the work.Copper suppresses rather than cures, and only when started early on snap beans; cultural steps stay the mainstay for a home crop.

  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 plants 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 plants 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. Do not plant beans in the same spot more often than every third year, and stay out of the planting when the foliage is wet.
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 every season with fresh certified seed rather than your own saved seed. Both of these blights begin on infected seed.Both pathogens are seedborne, so new certified seed each season is the primary break in the cycle.

  2. Crop rotation

    Give any one bed a three year break from beans. The bacteria can last as long as two years in the leftover debris of an infected crop.A three year interval outruns the up-to-two-year survival on residue in the bed.

  3. Water at the base

    Water at the base rather than overhead. Both blights move in rain and damp conditions, and overhead water does the same job for them.Overhead irrigation reproduces the rain splash both blights travel in; base watering removes that route.

  4. Staying out of wet foliage

    Stay out of the bean patch while the leaves are still wet. Brushing past wet plants carries the bacteria from one to the next.Handling wet foliage moves bacteria plant to plant, so timing your work to a dry canopy is a no-cost control, separate from how you water.

  5. Copper fungicide

    Infected plants do not recover, but copper sprays on about a 10 day schedule can slow the spread. Follow the label.Copper on a 10 day interval slows spread only; infected plants do not recover, so the seed and moisture steps carry the program.

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. The usual culprits are 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. The ones usually responsible are Rhizoctonia, Pythium, and Fusarium species. 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

    Hold off sowing until the soil reaches about 69°F at a depth of 4 inches. Seed that sits in cold, wet soil rots before it can come up.Sowing once soil reaches about 69°F at 4 inches cuts the time seed and seedling sit exposed in the cold, wet conditions these fungi exploit.

  2. Improve drainage

    Plant on raised beds in ground that drains well and stay out of low, wet spots. Cool, wet soil is what lets these root rots in.Raised beds on well-drained ground remove the standing wet that Rhizoctonia, Pythium, and Fusarium exploit; these fungi are resident, so the site is the lever rather than any treatment.

  3. Crop rotation

    Move beans around the garden each year, following them with other vegetables.Rotation with other vegetables is the residual step once site and sowing temperature are handled.

  4. Garden sanitation

    Pull the seedlings that have rotted, since there is no saving them, and clear the old plants after harvest. If you lose a stand, replant once the soil is warmer and draining better.Rotted seedlings do not recover: remove them, clear residue after harvest, and treat a replant into warmer, better-drained conditions as the only in-season recovery.

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 plants 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 choke off the stem. Affected pods collapse into a brown, watery mush, soon covered by a white cottony fungal growth. Dense, overfed plantings 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 plants that trap the still, humid air the mold needs.The fungus Sclerotinia sclerotiorum, favored by cool, moist conditions and heavy, dense plant 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 spacing between plants and rows so 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 between plants and rows to dry the canopy. Prevention Give plants and rows room for air to move instead of crowding them, and go easy on fertilizer, since too much makes the heavy growth the mold likes. Water at the base and avoid keeping the plants wet and packed together.Space plants and rows for good airflow rather than crowding, and go easy on fertilizer, since excess nitrogen feeds the heavy vine growth that favors the disease. 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 plants and rows enough space for air to move between them. This mold needs still, humid air inside a crowded canopy, so spacing is the main thing you control.Wider plant and row spacing dries the canopy the fungus depends on; with no recommended home-garden spray, layout carries most of the management.

  2. Balanced nitrogen feeding

    Go easy on the fertilizer. Too much nitrogen pushes heavy, leafy growth, and that dense canopy traps the damp, still air this mold needs.Excess nitrogen drives the lush vine growth that closes the canopy, so restrained feeding is the second half of the airflow strategy.

  3. Water at the base

    Water the soil, not the leaves, and try not to leave the plants wet and packed together.Base watering avoids adding to the cool, moist conditions under which lesions run together and choke the stem.

  4. Garden sanitation

    Pull and destroy infected plants rather than composting them. Nothing on the home-garden shelf is recommended against it, so how you grow and clean up is the whole program.Rogue out infected plants and destroy them; with nothing recommended chemically at the home-garden scale, removal plus canopy management is the whole of it.

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. Because beans feed the soil with nitrogen, whatever you plant there next will benefit.Rotate beans on a roughly three-year cycle. Their nitrogen-fixing habit makes them 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.Avoid following beans with beans or other legumes in the same bed; rotate to break the soil-borne disease cycle beans are prone to.
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 green beans (bush) 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 beans Time to sow beans
Plant bush 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 in moist, well-drained soil. There is no benefit to planting earlier. Direct-sow bush 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; there is no advantage to planting earlier.

Plant your next row of beans Sow your next short row of beans
Bush beans give a big crop over two to three weeks, then slow down. Plant a new short row now, about two weeks after the last one, to keep beans coming. Stop planting about two months before your first fall frost. Bush beans crop over a concentrated two-to-three-week window, then taper. Sow a fresh short row now, about two weeks after your last sowing, to keep fresh beans coming. Stop about two months before your first fall frost.

Start checking your beans every day Start checking your beans daily
Most bush beans are ready around 50 to 60 days. Start checking every day and pick firm, crisp pods that snap cleanly, before the seeds bulge through. Pick every two or three days to keep more beans coming. Most bush beans are ready around 50 to 60 days. Begin checking daily and pick firm, crisp pods that snap cleanly, before the seeds bulge. Harvest every two to three days to keep the plants producing.
