Garlic

in Zone 9, this week

Garlic is one of the easiest crops to grow, but it works on an unusual schedule. You plant the cloves in fall, they rest through winter (under a mulch blanket where it is cold), and they finish growing the next summer, so a single planting takes most of a year. Garlic needs that winter cold to form a proper bulb, which is why you plant in fall rather than spring. Grow hardneck garlic where winters are cold and softneck garlic where they are mild. Garlic (Allium sativum) is a hardy allium grown from individual cloves planted in fall. It roots before winter, overwinters in the ground (mulched in cold regions), then resumes growth in spring and matures the following summer, an eight to nine month crop that spans the year. Winter cold is essential: cloves must be vernalized to divide and bulb properly, which is why fall planting beats spring. Hardneck types suit cold winters, produce edible scapes, and store a few months; softneck types suit mild climates, braid well, and store the longest.

Seed to garden

Garlic does not grow from seed, you plant the cloves. Just before planting in fall, break a bulb into separate cloves and leave the papery skin on each one. Plant the biggest cloves pointy side up, about 2 to 3 inches deep and 4 to 6 inches apart. Big cloves grow big bulbs, so plant the largest and cook with the little ones. Start with healthy cloves from a trusted source so you do not bring in disease.Garlic is grown from cloves, not seed. Break apart firm, healthy bulbs into individual cloves just before planting, keep the papery skins on, and plant the largest cloves pointed end up about 2 to 3 inches deep and 4 to 6 inches apart in fall. Bigger cloves make bigger bulbs, so save the largest for planting and eat the small inner ones. Use clean, disease-free seed stock from a reputable source, since white rot and bloat nematode ride in on infected cloves.

The growing journey

Stage 01 · Planting & Rooting
01
Planting & Rooting
Days 0-30 · current stage
After you plant the cloves in fall, they grow roots underground and may send up a small green shoot before winter. This is normal. The garlic is settling in and starting to feel the cold it needs, not making big leaves yet.In fall you set cloves pointed end up, 2 to 3 inches deep and 4 to 6 inches apart. Over the next few weeks roots grow and a small shoot may push up before cold sets in; the cloves are anchoring and beginning to vernalize, not yet making top growth.
Plant the cloves at the right time for your area and water them in. In cold regions, once the ground begins to freeze, cover the bed with a few inches of straw or chopped leaves to protect the cloves over winter.Plant on time for your zone, water in, and once the ground starts to freeze in cold regions cover the bed with 3 to 4 inches of straw or shredded-leaf mulch to buffer the soil through winter and prevent freeze-thaw heaving.

02
Overwintering & Spring Shoots
Days 30-150
In cold areas the garlic mostly rests under its mulch all winter. In mild areas it keeps growing slowly. When spring arrives, green shoots come up and the plant starts making leaves.Through winter the plant is largely dormant under mulch in cold regions, or grows slowly in mild ones. As soil warms in late winter to early spring, green shoots emerge or resume and the plant begins building leaves, the leaves that will become bulb wrappers.
In spring, loosen the winter mulch if it is soggy, start feeding nitrogen as the shoots grow, and keep weeds pulled, because weeds easily crowd out young garlic.In spring, pull mulch back if it is matting wet over the crowns, begin nitrogen feeding as shoots resume, and keep the bed weed-free; garlic competes poorly with weeds and early weed control protects yield.

Start nitrogen as shoots resume and keep weeds out early.
03
Spring Leaf Growth
Days 150-210
The garlic grows lots of upright leaves in spring. This stage matters most for bulb size, because the leaves now turn into the layers of the bulb later. The more healthy leaves it grows, the bigger the bulb can be.The plant adds upright leaves through spring. This is the size-setting stage: each leaf corresponds to a bulb wrapper, so vigorous, uninterrupted leaf growth now sets the bulb-size ceiling. You want steady moisture and feeding, not a check from drought, weeds, or starvation.
Help it grow leaves now: keep the soil evenly moist, finish feeding nitrogen by early May, and keep weeds out. Feed early, because feeding late leads to soft necks that do not store.Push leaf growth: keep moisture even, finish nitrogen feeding by early May, and stay on top of weeds. Front-load feeding so the canopy is built before bulbing; nitrogen applied late delays bulbing and worsens storage.
FROM PLANT · The leaves garlic grows in spring become the layers of the bulb, so keep it watered and fed for strong leaf growth, but stop feeding nitrogen by early May so the bulbs form well.Garlic builds its bulb from the leaves it grows in spring, so push steady leaf growth with even moisture and nitrogen, and finish feeding by early May. Late nitrogen delays bulbing and gives thick necks that store poorly.
04
Scaping & Bulbing
Days 210-250
On hardneck garlic a curling stalk called a scape grows up from the middle in late spring. Around then the bulb starts to swell underground and the plant stops making new leaves. This is when the bulb puts on most of its size.On hardneck types a curling flower stalk (the scape) rises from the center in late spring; the base then begins to swell into a bulb as the plant shifts from leaves to filling cloves. Lower leaves start to age. This is the fast-fill window, when steady moisture translates directly into bulb size.
If you grow hardneck garlic, cut off the curly scape when it appears so the plant puts its energy into the bulb, and cook with the scape. Keep watering evenly while the bulb sizes up, and do not add more fertilizer now.On hardnecks, snip the scape off once it curls to redirect energy into the bulb (and eat it, it is a delicacy). Hold even moisture through sizing and keep nitrogen off; do not bend or knock down the tops to force maturity.

Keep watering evenly and stop fertilizing.On hardneck garlic, cut the scape once it curls to send energy into the bulb, and enjoy the scape in the kitchen. Keep moisture even through sizing and stop adding nitrogen.
05
Harvest
Days 250-275
The lower leaves turn brown and die back while the top leaves are still green. Garlic is ready when about a third to a half of the leaves have browned. Dig one bulb to check: if the cloves fill out the skins, it is time.The lower leaves brown and die back while several upper leaves stay green; the cue is when about a third to half of the leaves have turned, with roughly the lower half browning and five or so green leaves remaining (each green leaf is an intact wrapper). Pull a test bulb: if the cloves fill the skins and the wrappers are intact, it is ready.
Stop watering about two weeks before, then loosen the bulbs out of the ground with a fork on a dry day, handling them gently. Do not wait until all the leaves are brown, or the bulbs split open and store poorly.Stop watering about two weeks ahead, then lift, do not pull, the bulbs gently with a fork on a dry day to avoid bruising. Do not wait for all the leaves to brown, which over-matures the bulbs and splits the wrappers and storage.

06
Curing & Storage
Days 275-300
Just-dug garlic needs to dry before storing. Keep the bulbs with their tops on in a warm, dry, airy, shady spot for two to four weeks until the necks dry shut and the skins go papery.Freshly lifted bulbs are not storage-ready until cured: hung or laid out with tops attached in a warm, dry, airy, shaded place for two to four weeks, the necks dry tight and the outer wrappers turn papery, sealing the bulb against rot.
Dry the garlic in a shady, breezy place out of the sun, leaving the tops and roots on until it is fully dry. Then trim the tops and roots, brush off the dirt (do not wash it), and store it cool and dry. Keep your biggest bulbs to replant.Cure with good airflow out of direct sun, keeping tops and roots on until dry. Then trim tops to about an inch and roots close, brush off loose dirt (do not wash), and store cool and dry; save the biggest bulbs as next year's seed.
FROM PLANT · Dry the garlic with the tops still on in a warm, airy, shady spot for two to four weeks until the necks dry shut and the skins are papery. Then trim and store it cool and dry. Garlic that is not dried well rots.Cure bulbs with tops on in a warm, dry, airy, shaded place for two to four weeks until necks are tight and wrappers papery, then trim and store cool and dry. Poor curing is the main cause of garlic rotting in storage.

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

Garlic likes loose, rich soil that drains well but still holds some moisture, with plenty of compost worked in. Loosen the bed deeply before planting so the roots and bulbs have room. The thing it cannot stand is soggy, waterlogged ground, which rots the cloves over winter, so avoid heavy clay and any low spot where water sits.

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.

In a pot

Yes, 3 gallons and up

Garlic grows fine in a deep pot because its roots are not huge. Use a container at least 8 inches deep with drainage holes, plant cloves 4 to 6 inches apart in fall, and plan to leave it out all winter. Keep it watered in spring and stop a couple of weeks before harvest.Garlic is workable in containers given depth and drainage. Use a pot at least 8 inches deep, 3 gallons or more, set cloves 4 to 6 inches apart in fall, and treat it as a year-long resident: it overwinters in the pot and matures the next summer. Containers dry fast in spring, so water steadily through bulbing, then cut water two weeks before harvest. The main risk is winter waterlogging in a pot that drains poorly.

Pot size
3 gallons and up; 5 gallons is comfortable
Drainage
Drainage holes are a must. Skip the gravel layer. After you water, pour out any water that collects in the saucer. Garlic should never sit in standing water, because soggy soil rots the cloves, especially over winter.Drainage holes are a must. Skip the gravel layer. Empty the saucer after each watering; garlic must never sit in standing water, which saturates the bulb zone over winter and rots the cloves.
Watering
Pots dry out faster than the ground, so check often in spring growth, but do not keep the mix soggy over winter or the cloves rot.Expect to water more often than in-ground during spring growth; the shallow pot volume dries quickly and a drought check at sizing shrinks bulbs. Keep the mix on the dry side over winter to avoid clove rot.
Depth and shape
At least 8 inches deep. wide_and_deep_enough_for_overwinter_roots
Self-watering pot
No. Self-watering containers are a poor match for garlic: the constantly moist reservoir keeps the bulb zone too wet over the long overwinter and during the curing-down before harvest, both of which invite clove and bulb rot. A free-draining pot you water on demand is safer.
Mix
A free-draining potting mix blended with compost. Work in compost for fertility and a slow-release balanced feed at planting; keep the mix free-draining for the long overwinter.
Feeding
Frequent spring watering leaches nutrients, so feed container garlic lightly but regularly through leaf growth, then stop by early May as in the ground.
Winter

Garlic in a pot is meant to overwinter, since you plant it in fall and harvest the next summer. In cold areas the roots in a pot freeze harder than in the ground, so sink the pot, move it against the house or into an unheated shed or cold frame, or mulch it well, and let it freeze and rest rather than trying to keep it growing.Overwintering is the whole point of a garlic container: fall-planted, it sits dormant through winter and finishes the next summer. The limited root volume of a pot freezes colder than open ground, so in cold zones sink the pot, move it to a cold frame or unheated structure, or heap mulch around it; the goal is to carry the cloves safely through the cold, not to force winter growth.

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 garlic

Preferred
6 to 7
Tolerated
5.5 to 7.5

Garlic grows best in soil close to neutral, about 6.0 to 7.0. It is not very fussy, but very acidic ground holds it back, so if a soil test reads below about 6.0, mix in some garden lime before you plant in fall.Aim for a soil pH of about 6.0 to 7.0; garlic tolerates a slightly wider band, roughly 5.5 to 7.5, but yields fall off on strongly acidic soils. Test the bed the season before and lime an acid plot up toward neutral, since fall is your one planting window and there is no second chance to adjust mid-season.

Watering

When & how much
Frequency
Water garlic regularly in spring so the soil stays evenly moist, roughly an inch a week. Then stop watering a couple of weeks before harvest so the bulbs can dry down and the skins set.Keep the soil evenly moist through spring leaf growth and bulbing, about an inch of water per week including rain. Then taper and stop watering about two weeks before harvest so the bulbs firm up and the wrappers cure clean.
Amount
About one inch of water a week while the plants are growing in spring, and a bit more in warm, dry weather. Steady is better than a flood one week and nothing the next.Roughly one inch of water per week from rain plus irrigation through the spring growing season; more in warm, dry, or sandy conditions, delivered steadily rather than in swings.
Method
Water the soil at the base of the plants, not over the leaves. Keeping the tops dry helps prevent disease.Water at the base with drip or a soaker to keep the foliage dry; wet leaves and standing water feed the leaf and bulb rots garlic is prone to.
Signs of trouble
Too much water
If the soil stays soggy and the bottoms of the plants turn yellow and soft, that is too much water. Garlic sitting in wet soil rots.Yellowing, soft lower leaves and a sour smell signal waterlogging; saturated soil over winter and at bulbing drives white rot, basal rot, and neck rot.
Too little water
Wilting, blue-tinged, or brown-tipped leaves in spring mean the garlic is too dry. Garlic that dries out while sizing makes smaller bulbs.Bluish, tip-burned, or prematurely dying leaves and stalled growth mean the bulbs are short of water during the spring sizing window, which caps final bulb size.

When to start
Work fertilizer in at fall planting, then side-dress nitrogen as shoots grow in early spring; stop by early May

Garlic is a hungry plant that makes its bulb from the leaves it grows in spring, so feed it then. Mix some compost or fertilizer into the soil when you plant in fall, then give it a nitrogen feeding once the green shoots are growing well in early spring, and again a few weeks later. Stop feeding before the bulbs start sizing up, which falls around April in warm regions and into May where winters are cold. Feeding late makes leafy plants with thick necks and small bulbs that do not keep well.Garlic has a moderate to high nitrogen demand and builds its bulb on the leaves it grows in spring, so feeding is front-loaded onto the spring vegetative push. Mix a complete fertilizer or compost into the bed at fall planting, then side-dress nitrogen as the shoots resume growth in early spring and again two to three weeks later. The exact cutoff tracks your season rather than a fixed calendar date. In cold-winter regions with a later crop, the last feedings run later: Utah State suggests about half a pound of 21-0-0 per 100 square feet in mid-April with a quarter pound in late May, and the University of Minnesota feeds through spring growth before bulbing. In the warm Southeast, where the crop runs weeks earlier, UGA advises no nitrogen after the first week of April. The unifying rule is to stop nitrogen several weeks before bulbing begins, since late feeding delays bulbing, thickens necks, and worsens storage.

High nitrogen in spring

Use a feed higher in the first number (nitrogen) such as blood meal or a 21-0-0 fertilizer in spring, then stop by early May.Higher first-number (N) feeds in spring, e.g. ammonium sulfate (21-0-0) or blood meal; taper off and stop by early May so bulbing is not delayed.

Try ammonium sulfate (21-0-0), blood meal, or a balanced vegetable fertilizer
Who grows well together

Companion planting

Garlic is famous as a good-neighbor plant, mostly because its strong smell is thought to keep aphids and some other pests away, so it is often tucked among roses, fruit trees, tomatoes, and cabbage-family plants. The one thing to keep it away from is beans and peas, since garlic and its onion relatives are believed to slow those down. These are helpful traditions, not sure things, so do not worry if your garden does a little differently. Garlic's companion reputation rests almost entirely on its sulfur scent, traditionally credited with deterring aphids, spider mites, and some borers, which is why it is interplanted among roses, fruit trees, tomatoes, and brassicas. The one firm caution is the legume conflict: alliums are widely held to inhibit beans and peas, so keep garlic away from them. Most of these pairings are traditional rather than trial-proven, and garlic's long fall-to-summer occupancy means it shares the bed with whatever overwinters or goes in around it; treat the pairings as low-risk suggestions, not guarantees.

Other
Tomatoes
Garlic's strong smell is thought to help keep aphids and spider mites off tomatoes, and the two fit together in the bed because garlic is finishing up in early summer as tomatoes take off.Tomatoes are a traditional garlic companion on the allium pest-repel reputation, the scent said to discourage aphids and spider mites, plus a tidy timing fit: fall-planted garlic is sizing and harvested in early summer just as tomatoes need the room. The pest claim is folk wisdom rather than a tested effect, but the pairing is low-risk and space-efficient. Traditional
Roses and fruit trees
Garlic is a classic underplanting for roses and fruit trees, where its smell is believed to help fend off aphids and borers. It takes little room and is harvested before midsummer.Underplanting roses and fruit trees with garlic is a long-standing tradition, the pungent foliage credited with deterring aphids and some borers. It is a space-and-scent pairing rather than a demonstrated effect; garlic's small footprint and early-summer harvest make it an easy, low-competition neighbor for perennials. Traditional
Brassicas (cabbage, broccoli)
Cabbage-family plants share garlic's cool-season liking, and the strong garlic smell is thought to bother some of their pests like aphids and cabbage worms.Brassicas are interplanted with garlic on the same allium-scent logic used for onions: the sulfur smell is traditionally credited with masking the cabbage family from aphids and caterpillars. Garlic is shallow and undemanding, so it tucks between cole crops without competing, though the pest benefit is traditional rather than trial-proven for garlic. Traditional
Carrots and beets
Garlic grows alongside carrots and beets without crowding them, and its smell is said to help confuse pests like the carrot rust fly. They use different space above and below ground.Carrots and beets pair with garlic on complementary form and the allium scent-masking tradition, the same logic behind the well-known carrot-and-onion pairing against carrot rust fly. Garlic sends a narrow bulb down with little leafy spread, so it shares space efficiently. The scent-masking effect is best evidenced for onions; for garlic treat it as a reasonable, low-risk extension. Traditional
Keep apart from
Beans and peas Keep garlic away from beans and peas. Garlic and its onion relatives are long believed to slow the growth of these legumes, so plant them in separate parts of the garden.Beans and peas are the standard allium caution: garlic, like onion, is traditionally held to inhibit legume growth, so the two are kept apart. The mechanism is not firmly established, but the recommendation is consistent across companion guidance, so separate garlic from beans and peas as a low-cost precaution. Traditional

Harvest signals

When to pick

Garlic is ready in early summer (or late spring in warm areas) when the lower leaves have turned brown but the top leaves are still green, about a third to half of them browned. Do not wait for all the leaves to die. Dig one bulb to check: if the cloves fill out the skins, it is time to harvest.Garlic is ready in early to mid summer (late spring in warm regions) when the lower leaves have browned and died back while several upper leaves stay green, about a third to half the foliage turned. Each green leaf is an intact wrapper, so do not wait for all the leaves to brown. Confirm by lifting a test bulb: ready bulbs have cloves that fill the skins.

Yield

What to expect

Each clove you plant grows into one whole bulb, and each bulb has about 10 to 15 cloves inside. So a handful of cloves planted in fall becomes a basket of garlic the next summer.One bulb per planted clove, and each bulb typically holds 10 to 15 cloves (fewer, larger on hardnecks; more, smaller on softnecks). A 10-foot row at about 5-inch spacing yields roughly 24 bulbs.

All your garlic of one kind finishes around the same time in summer, so you harvest it together, then cure it and store it to use over the following months.Garlic of a given variety matures together in one main flush in early to mid summer, so the harvest comes all at once rather than over a long window; it is then cured and stored for months. The most important things for a good first harvest are choosing the right type for your winters and planting big cloves in fall. The wrong type, or planting in spring, gives small bulbs.Matching type to your winter (hardneck where winters are cold, softneck where mild) and planting good-sized cloves in fall are the biggest first-year levers; the wrong type for your climate, or spring planting, gives small or split bulbs.

Pick your variety

Recommended varieties

Pick the type that matches your winters first. In cold-winter areas, grow hardneck garlic (like Music, Spanish Roja, or Chesnok Red), which needs real cold, makes big cloves, and gives you edible scapes, but does not store as long. In mild-winter and southern areas, grow softneck garlic (like Inchelium Red or California Early), which handles warm winters, makes lots of cloves, braids nicely, and keeps the longest. If you are not sure, Inchelium Red is forgiving in many climates. Elephant garlic is not really garlic, it is a mild leek relative.Choose by winter cold first, then by use. Hardneck garlics (Rocambole, Porcelain, Purple Stripe groups, such as Music, German White, Spanish Roja, Chesnok Red) need a genuine cold winter to vernalize and bulb, produce edible scapes, have fewer larger cloves, and store a shorter time, so they shine in the North. Softneck garlics (Artichoke and Silverskin groups, such as Inchelium Red, California Early and Late, Creole and Silverskin types) tolerate mild winters, yield more smaller cloves, braid well, and store the longest, so they are the choice for the South and warm regions. Where winters are mild, lean softneck; where winters are cold, hardnecks reward you with flavor. Elephant garlic is a leek relative, not true garlic.

Storing your harvest

Room temp
Once the garlic is cured (dried), keep the bulbs somewhere cool, dry, and airy, out of the light. A cool pantry works for a while; a steady cool spot keeps them longest. Damp or warm places make garlic sprout and soften.After curing, store cured bulbs in a cool, dry, airy place. The classic storage range is cool and dry, around 32 to 40°F for long holding, though many cooks simply keep braids or bulbs at a cool room temperature out of light. Warm, humid spots and the 40 to 60°F range encourage sprouting.
Fridge
Do not store whole garlic bulbs in the fridge. The cold, damp air actually makes them sprout. Keep cured bulbs in a cool, dry cupboard instead. You can refrigerate a few peeled cloves for a day or two if it is handy.Whole cured bulbs store poorly in the refrigerator: the 40 to 50°F, humid environment is exactly what triggers sprouting, so keep them cool and dry instead. Peeled cloves can be refrigerated briefly for convenience.
Freezer
You can peel and chop garlic and freeze it for cooking. It goes soft after thawing, so use frozen garlic in cooked food, not raw.Garlic freezes well peeled and chopped, or as a puree, for cooking; texture softens, so use frozen garlic in cooked dishes rather than raw.

Pests
Onion thrips
P · 01
Cause A tiny insect called onion thrips. It multiplies fast in warm, dry weather and hides in the tight folds of the leaves.Onion thrips (Thrips tabaci) build through warm, dry weather and shelter in the leaf axils where sprays miss them; they move readily between alliums.
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. Garden sanitation

    Once the garlic is harvested, clear the old tops, trimmings and any volunteer garlic or onions out of the bed and from around it, and get the material out of the garden rather than leaving it in a heap. Thrips spend the winter in onion-family debris left on the ground and in volunteer plants, and next year's population starts from what you leave behind.Sanitation is the standing cultural control for onion thrips: they overwinter in allium debris left on the soil surface and in volunteer plants, so clearing tops, trimmings and volunteers after harvest removes the local carryover. The spring influx that matters most comes from that debris and from grain or alfalfa drying down nearby, which is why bed choice against those neighbors sits alongside the cleanup.

  2. Water spray

    If there are only a few thrips, wash them off with a jet of water from the hose. Aim into the tight folds where the leaves meet, because that is where they shelter. Do it early in the day so the leaves dry off afterward.A forceful water jet handles light infestations. Direct it into the leaf axils, the tight folds where leaf meets stem, since that is where the insects shelter and the part of the plant a spray of any kind tends to miss. Work early in the day so foliage dries quickly.

No spray for this one. Prevention is the control.

Onion maggot
P · 02
Cause The larvae (maggots) of a small fly that lays its eggs at the base of the plants. It spends the winter in the soil where onions or garlic grew the year before, and old bulbs and rotting garden waste draw it in. Garlic usually gets off lighter than onions.Larvae of the onion maggot fly (Delia antiqua), which lays at the base of the plant; the pupae overwinter in the soil around last season's alliums, and cull bulbs and volunteer onions keep the fly going between crops. Rotting organic matter and spring manure draw egg-laying. Garlic is generally a lesser host than onion.
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 garlic in a different spot rather than returning to the same bed each year. This pest carries over where alliums (garlic, onions, and their relatives) have grown, so a fresh bed starts the crop away from it.Populations carry over in allium ground, so rotating garlic off beds that recently grew alliums puts the crop out from under the carryover. Rotation and cleanup are the pair that does the work here, since cultural sanitation is described as the main home-garden tool for this pest.

  2. Garden sanitation

    Clear away leftover onion and garlic debris, including cull bulbs, the small or damaged ones you set aside and did not use. The fly breeds in that material, and clearing it is the main home-garden tool against this pest.Removing cull bulbs, volunteer onions and lifted plants with their roots takes away what the fly breeds in and what the pupae overwinter around, and with no home-garden insecticide available it is the main lever there is. Get what you clear right out of the garden rather than piling it at the bed edge, since a cull pile is where the fly multiplies.

No spray for this one. Prevention is the control.

Stem and bulb nematode (garlic bloat nematode)
P · 03
Cause A microscopic worm that lives and feeds inside the leaves, stems, and bulbs. It usually arrives on infected cloves you plant and can survive dried in the soil for years.The stem and bulb nematode (Ditylenchus dipsaci), the garlic bloat nematode, a microscopic worm that feeds inside the leaves, stems, and bulbs. It rides in on infected planting cloves and survives dried in soil and debris for at least four years, favored by cool, moist conditions.
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

    Buy clean, tested cloves from a trusted source rather than replanting your own. This nematode usually arrives inside the planting cloves, so starting clean is the single most important step here. Hot-water dips are no longer advised, since they reduce the nematode without clearing it.Nematode-free, tested seed stock is the primary control, since infected cloves are the usual route into a garden and the pest then persists in soil and debris for years; a clean start is worth more than anything applied afterward. Hot-water seed dips are no longer recommended, because they only reduce rather than eliminate it.

  2. Crop rotation

    Keep garlic and onions out of that spot for four years. The worm can survive dried in the soil and in debris for at least four years, so a one-season break is not enough. Poor-host crops, ones it does not feed and multiply well on, are fine to grow there meanwhile: carrots, potatoes, spinach, corn, and wheat.Rotate garlic out for four years with poor-host crops such as carrots, potatoes, spinach, corn, and wheat. The length is set by the nematode itself, which persists dried in soil and debris for at least that long, so the four years is the point rather than the fact of rotating.

  3. Garden sanitation

    Pull infected plants and throw them away rather than composting them, and take the debris with them. The worm lives and feeds inside the leaves, stems, and bulbs, so it leaves with the plant it is in.Remove and destroy infected plants along with the debris. The nematode feeds inside leaf, stem, and bulb tissue, so roguing carries the population out with the plant; leaving that tissue in the bed or in the compost returns it to the soil it survives in.

No spray for this one. Prevention is the control.

Diseases
White rot
D · 01
Cause A soil fungus that makes tiny long-lived resting bodies that can sit in the ground for years and attack in cool weather. It spreads on dirty tools, soil, and infected cloves.The fungus Sclerotium cepivorum, which produces hardy sclerotia that survive in soil for many years and germinate in the cool soils garlic grows in (activity is restricted above about 75°F). It spreads on contaminated soil, tools, and infected cloves.
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 disease-free cloves in clean ground. Infected cloves are one of the ways this fungus arrives, and it is worth settling before planting because there is no cure once the soil carries it.Infected cloves are one of the listed routes this fungus travels, so disease-free planting stock is set once, at purchase, and it is the step that keeps clean ground clean. It carries more weight here than on most diseases: there is no cure once soil is infested, and the fungus persists there for years.

  2. Crop rotation

    Keep garlic and other alliums out of an affected bed for years rather than a single season. The fungus leaves behind tiny hard resting bodies that can sit in the soil a long time waiting for the next allium crop.Long allium-free rotations are the answer to sclerotia, the hardy resting bodies this fungus makes, which survive in soil for many years. It germinates in the cool soils garlic grows in, and its activity is restricted above about 75°F.

  3. Garden sanitation

    Pull sick plants and destroy them rather than composting them. Keep soil from an infested bed out of clean ground as well, and clean the dirt off tools after working there, since this fungus travels on soil, tools, and infected cloves.Rogue and destroy infected plants, and treat the soil itself as a thing that moves: contaminated soil, tools, and cloves are the listed routes of spread, so avoid carrying soil out of an infested bed and clean equipment after working it. With no cure once the ground is infested, keeping the fungus away from clean beds is what the management rests on.

No spray for this one. Prevention is the control.

Fusarium basal rot
D · 02
Cause A soil fungus that lives in the ground for years and does the most damage in warm soil. Injuries and infected cloves let it in.Soilborne Fusarium oxysporum (including f. sp. cepae) and related species that persist in soil for years and progress fastest in warm soils (about 77 to 82°F); wounds, maggot feeding, and infected cloves open the door.
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

    Plant clean, tested cloves. Infected cloves are one of the openings this soil fungus uses, along with injuries to the bulb and maggot feeding, and it is the one you can settle before anything goes in the ground.Clean, tested cloves close one of the three listed entry points; wounds and maggot feeding are the other two. It is the entry point decided at purchase rather than in the bed, which is what puts it first.

  2. Resistant varieties

    Where you can find it, choose stock that is less susceptible to this rot. It is not offered for every variety, so treat it as a help when it is available rather than the whole plan.Less-susceptible stock is worth seeking at seed-buying time where it exists. Availability is the limit on it, so it supplements the rotation rather than standing in for it.

  3. Crop rotation

    Do not grow garlic or other alliums in the same spot for several years. The fungus lives on in the ground for years, so moving the crop puts distance between it and the new planting.Rotate out of alliums for several years. The fungus persists in soil across seasons and progresses fastest in warm soils, roughly 77 to 82°F, so what you are managing is the bed's history rather than this season's weather.

  4. Cure and store the harvest

    Handle the bulbs gently as you lift and dry them, then store them cool and dry. This fungus gets in through injuries, so the bruises and nicks of a rough harvest are the opening it uses.Gentle handling and correct storage act on the entry route rather than on the organism: wounds are what let it in, and this crop's guidance puts cured bulbs cool, below about 39°F, and dry. It protects sound bulbs and does nothing for one already infected in the ground.

No spray for this one. Prevention is the control.

Botrytis neck rot
D · 03
Cause A mold that gets into the necks of garlic that was harvested too green or dried poorly. Too much late fertilizer and wet weather near harvest make it worse.Botrytis species that overwinter on debris and infected bulbs and as sclerotia in soil; excess late nitrogen, rain or irrigation late in the season, and inadequate curing or storage all worsen it.
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

    Stop feeding nitrogen by early May. Too much late fertilizer is one of the things that makes this rot worse, along with rain or watering close to harvest and drying the bulbs poorly after they come up.Cut nitrogen by early May. Excess late nitrogen is listed among the factors that worsen neck rot, alongside late-season rain or irrigation and inadequate curing or storage, and it is the one the feeding schedule settles outright.

  2. Cure and store the harvest

    Dry the garlic down after lifting until the necks are tight, then keep it somewhere cool, dry and airy. The mold gets into bulbs that were pulled green or dried poorly, so the curing is what shuts that door.Curing until the necks are tight and dry is the control this disease turns on, since it enters through necks left soft by a green harvest or an inadequate cure. Handle gently to avoid the wounds it also uses, and hold the cured crop cool, dry and with air moving. Take the conditions from this crop rather than from another.

No spray for this one. Prevention is the control.

Garlic rust
D · 04
Cause A rust fungus that spreads in cool, damp weather through wet leaves and splashing water.A Puccinia rust fungus favored by cool temperatures, leaf wetness, and high humidity; spores spread on wind and splashing water and overwinter on volunteer alliums.
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 garlic patch rather than replanting the same bed. Rotating is one of the cultural steps named for rust, and since rust is usually a minor problem on garlic those steps are generally enough in a home garden.Rotation is part of the cultural package named for garlic rust. The disease is usually minor here, though worse in cool, humid, crowded plantings and notably in coastal and mild-winter areas, and the cultural steps are described as generally sufficient at garden scale.

  2. Airflow and spacing

    Give the plants enough room for air to move between them. Crowded plantings in cool, damp weather are where this rust does the most, so spacing gives the leaves a chance to dry.Space for airflow. The fungus is favored by cool temperatures, leaf wetness, and high humidity, and it runs worse in crowded plantings, so spacing is the layout decision that shortens leaf wetness.

  3. Balanced nitrogen feeding

    Go easy on the fertilizer. Too much nitrogen is called out as something to avoid where rust shows up, and heavy feeding also thickens the stand, which is the crowding the spacing above is meant to relieve.Avoid excess nitrogen, named among the things to keep off a rust-prone planting. Heavy nitrogen pushes the dense growth that holds a canopy wet, so it works against the spacing rung rather than beside it.

  4. Water at the base

    Water at the soil rather than over the top of the plants. The spores travel in splashing water and the fungus needs wet leaves, so keeping the foliage dry works against both.Skip overhead watering. Spores spread on wind and on splashing water, so basal irrigation removes the splash route and holds leaf wetness, one of the conditions the fungus needs, to whatever the weather forces on you.

  5. Clearing the weeds that host it

    Pull out volunteer onions and garlic near the bed, the ones that come up on their own from bulbs left behind. The rust survives the winter on them, so they carry it forward into the next crop.Remove volunteer alliums around the planting. The fungus overwinters on them, which makes them a live reservoir sitting outside the rotation; rotation moves the crop you planted and does nothing about the ones that came up on their own.

  6. Garden sanitation

    Pick off the badly spotted leaves and get rid of them. A heavy case yellows the leaves, kills them back early, and leaves you with smaller bulbs, so removing the worst of them is about the harvest rather than about tidiness.Remove badly infected leaves. Heavy infection yellows the foliage, brings on early dieback, and reduces bulb size, so taking out the worst leaves is aimed at what the bulb has left to size on.

No spray for this one. Prevention is the control.

Where to plant next year

Crop rotation

Keep moving garlic around the garden. Wait about 4 years before planting garlic, onions, or leeks in the same spot, because soil diseases and the nematode build up there. Following garlic with crops like carrots, potatoes, or corn, which the nematode does not feed on, helps clean the ground.Rotate so garlic and its allium relatives do not return to the same bed for about 4 years. White rot sclerotia survive in soil for years and bloat nematode persists in debris, so a long rotation away from the whole family is the core defense. Carrots, potatoes, spinach, corn, and grains are good rotation crops because they are poor hosts for the bloat nematode.

When plant taps you on the shoulder

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

plant
3 weeks before first frost
Time to plant garlic Plant garlic this fall
Plant garlic cloves in fall, around the time of your first hard frost, so they grow roots before winter. Put the biggest cloves in pointy side up, 2 to 3 inches deep and 4 to 6 inches apart. In mild or southern areas, use softneck garlic. Plant cloves in fall, generally a few weeks before to just after your first hard frost, so they root before the ground freezes. Set the largest cloves pointed end up, 2 to 3 inches deep and 4 to 6 inches apart. In mild and southern regions, choose softneck types.

plant
7 days after first frost
Cover your garlic for winter Mulch garlic for winter
In cold areas, once the ground starts to freeze, cover the garlic with a few inches of straw or chopped leaves. This protects the cloves through winter and keeps the freezing and thawing soil from pushing them up. In cold regions, once the ground begins to freeze, cover the bed with 3 to 4 inches of straw or shredded-leaf mulch. It buffers soil temperature swings and prevents freeze-thaw heaving that can push cloves out of the ground over winter.
p
plant
Feed your garlic in spring Feed garlic as spring shoots resume
When green shoots start growing in early spring, feed your garlic a nitrogen fertilizer to grow lots of leaves, and feed again a couple of weeks later. Stop feeding by early May. As shoots resume growth in early spring, side-dress nitrogen to drive the leaf growth that sets bulb size, and repeat in two to three weeks. Stop nitrogen by early May; late feeding delays bulbing and worsens storage.
