Plant garlic in fall, after the weather has cooled but before the ground freezes. In colder climates, a useful rule of thumb is to plant about 1 to 2 weeks after the first killing frost, giving the cloves time to develop roots before winter.

Garlic needs a period of cold temperatures for good bulb development. Fall-planted garlic receives this chilling naturally over winter. If you plant garlic in spring, chill the cloves in the refrigerator for about 8 weeks beforehand, then plant as soon as the soil can be worked.

In many areas, garlic goes into the ground around the same time as spring-flowering bulbs, generally from September through November. Gardeners in mild-winter climates may plant later, but spring-planted garlic often produces smaller bulbs.

Where to Plant Garlic

Plant garlic in full sun, with at least 6 to 8 hours of direct sunlight per day, and in fertile, well-drained soil. Before planting, work compost or other well-rotted organic matter into the soil to improve its structure and fertility.

Good drainage is especially important. Garlic can rot in soil that stays wet, so if you have heavy clay or poorly drained soil, consider planting in a raised bed.

How to Plant Garlic

Plant garlic as individual cloves, 2 to 3 inches deep and about 4 to 6 inches apart, with the pointed end facing up. Separate the cloves from the bulb just before planting, and leave the papery skins intact.

Start with healthy seed garlic. Choose large, firm, disease-free bulbs from a reputable nursery, garden center, or seed supplier.
Separate the bulb into cloves just before planting. Use the largest healthy cloves and keep their papery skins on. Larger cloves generally produce larger bulbs.
Plant each clove 2 to 3 inches deep, with the pointed end facing up.
Space cloves about 4 to 6 inches apart. If planting in rows, leave enough room between rows for weeding and tending the plants.
Water after planting to settle the soil around the cloves.

Growing

Watering

Keep garlic evenly moist during active spring growth, especially as the bulbs begin to form. Garlic generally needs about 1 inch of water per week from rain or irrigation during dry weather, but avoid keeping the soil soggy.

As the lower leaves begin to yellow and harvest approaches, reduce and then stop watering. Too much moisture late in the season can delay curing and increase the risk of bulb problems.

Fertilizing

Garlic benefits from nitrogen while it is producing vigorous leafy growth in spring. Side-dress plants with a nitrogen-rich fertilizer when active growth resumes. In lower-fertility soils, a second light feeding may be helpful before the bulbs begin to enlarge.

Avoid heavy fertilizing once bulb formation is underway. A soil test is the best guide to whether your soil needs additional nutrients.

Pruning or Maintenance

Keep garlic beds weeded throughout the growing season. Garlic has shallow roots and does not compete well with weeds for water and nutrients.

If you are growing hardneck garlic, cut off the flower stalks, called scapes, after they emerge and begin to curl. Removing scapes helps the plant direct more energy into producing larger bulbs. The tender scapes are edible, too.

Seasonal Care

In cold-winter areas, a layer of straw or chopped leaves helps protect fall-planted garlic from repeated freezing and thawing. As growth resumes in spring, loosen or pull back heavy, matted mulch so the shoots can emerge easily.

A lighter layer of mulch can remain through the growing season to conserve moisture and suppress weeds.

Types

Garlic comes in two main types: hardneck and softneck. The best choice depends largely on your climate and whether you value scapes, large cloves, or longer storage.

Hardneck garlic is generally more winter-hardy and is a good choice for colder climates. It produces a stiff central stalk and edible scapes, with fewer but typically larger cloves. Hardneck garlic does not store as long as softneck types. Popular varieties include ‘Chesnok Red’ and ‘German Red’.
Softneck garlic is well suited to many milder climates and generally stores longer than hardneck garlic. It usually produces more, smaller cloves and has flexible stems that can be braided after curing. Popular varieties include ‘California Early’ and ‘Inchelium Red’.

Harvesting

When to Harvest Garlic

Harvest garlic when about one-third to one-half of the leaves have turned yellow or brown, while several upper leaves are still green. Don’t wait until all the foliage has dried, or the bulbs may begin to split apart and won’t store as well.

Garlic planted in fall is typically ready to harvest the following summer, usually from June through August depending on your climate and the variety. If you’re unsure, carefully dig up one bulb to check it. Mature bulbs should have plump, well-defined cloves covered by several layers of papery skin.

If you’re growing hardneck garlic for scapes, harvest the scapes earlier in the season when they begin to curl.

How to Harvest Garlic

Loosen the soil around each bulb with a garden fork or shovel, taking care not to pierce or bruise it. Lift the whole plant from the soil rather than pulling hard on the stem.

Gently brush away large clumps of soil, but leave the leaves and roots attached while the garlic cures.

Storage

Garlic can be used fresh from the garden, but bulbs intended for storage should be cured first.

Place freshly harvested garlic in a warm, dry, shady location with good air circulation for about 2 to 4 weeks. Garlic is fully cured when the outer skins are papery, the neck and roots are dry, and the cloves feel firm.

After curing, gently brush away loose soil. Trim the roots and cut the stems to about 1 to 2 inches above the bulb, unless you’re growing softneck garlic and want to braid the tops.

Store cured garlic in a cool, dry, dark place with good air circulation. Softneck garlic generally stores longer than hardneck garlic.

Save a few of your largest, healthiest bulbs if you’d like to plant your own garlic again in fall.

Pests and Problems

Common Problems

Bulbs are small or undersized: Crowding, low fertility, dry soil during active growth, planting too late, or leaving scapes on hardneck garlic can all limit bulb size. Give plants adequate space, steady moisture, and nutrients while they are actively growing.
Bulbs are splitting apart: Garlic may begin to separate into individual cloves when it is left in the ground too long. Harvest when the lower leaves have browned but several upper leaves are still green.
Leaves are turning yellow: Some yellowing is normal as garlic approaches harvest. If leaves yellow or wilt earlier in the season, check soil moisture and look closely for pest or disease symptoms before adding fertilizer.

Common Pests

Plants suddenly yellow or wilt, and bulbs have holes: Onion maggots may be feeding on the roots and bulbs. You may find small, cream-colored, legless maggots inside damaged bulbs. Remove badly affected plants, rotate garlic and other alliums to a different part of the garden, and use floating row covers where onion maggots have been a recurring problem.
Leaves develop whitish or silvery streaks and may become distorted: Check between the leaves for tiny onion thrips. Small infestations usually cause little damage in home gardens. Keep weeds under control, use mulch, and knock thrips from the foliage with a strong spray of water if needed.

Plant Diseases

Leaves yellow and wilt, and the base of the bulb develops fluffy white growth: These are signs of white rot. Small black, poppy-seed-like structures may also appear around the bulb. Remove infected plants and avoid moving contaminated soil or bulbs to other parts of the garden. Plant only clean, disease-free garlic in unaffected soil. White rot can survive in soil for more than 20 years, so crop rotation alone will not eliminate it.

I didnot plant my garlic yet due to a back problem, my soil is frozen about 2in deep, I put A small clere plastic hoop type cover over the area I wanted to use, is it to late to go and plant when soil is workable? should I keep hoop on or remove it once I plant the garlic? is this better than puting garlic in my refrigator for the winter?

You should plant it to get the winter chilling it needs to grow well. I had the same problem in 2010 with a head of garlic I had ordered that arrived while I was recovering from an accident. What I did was to start the cloves in peat pots in my garage. Then I covered the planting bed with black plastic to gain solar heat to keep it from freezing. About the time the cloves broke the soil in the peat pots I planted them and watered them in on a fairly warm 38 degree day. Then I mulched the bed with straw and crossed my fingers. In the spring it all came up and grew just fine.

It is now end of May here in NC..Just got a bunch of garlic to plant. How do I store them till Sept. Looks like it is to late to plant now. Or is it? Trying for first time I guess I order to late

Using Garlic from groceries for planting is the only option i have left. I want to plant garlic for home consumption and sale on the local market but i have failed to find farmers in Uganda that have big and healthy bulbs apart from that imported and sold in groceries. the local available bulbs are too small. Am also afraid that the grocery big bulbs-cloves will not yeild any bulbs because they are from groceries just like i read somewhere in the posts/comments. How true is this and can i go ahead to plant grocery garlic and follow all growing instructions?

I have 'California White' soft neck and 'Music' hard neck that came from grocery stores more than 20 years ago. They took a few years to develop, but they eventually adapted and have grown well for me in different parts of the US. The concern of store bought garlic is that it is not seed grade and may be carrying some sort of pathogen, If I was you, I'd try all varieties available and test grow them in plots that are separated just in case there's a problem with one type. It will take a few years to determine how well each will perform in your garden. Your locally available garlic that is small may be due to planting time or from not having enough time to develop.

Thanks Jbush for your reply and advice. Am encouraged by your trials and hope to keep in touch for more advice.

I grow several types of garlic in my Zone 5 garden in Northern Nevada. My best luck has been planting from mid October until just before the ground freezes. I can usually harvest the early varieties in mid June. I harvest when 3 or 4 leaves turn brown, About half of it is left in the ground until I need it. This year I dug 'Inchelium Red' after 2 years and the heads were huge!

Maurine Spinato Tue, 11/12/2013 - 11:41

I want to plant my garlic in a pot and leave it on my deck. How big a pot do I need, this is the first time I have tried planting garlic. I live in the Hartford conn. Area

Osu Beaver Tue, 12/03/2013 - 13:27

I plant mine in a six gallon bucket. One in the center and five or six around the edge about two inches from the side. The roots grow all the way to the bottom of the bucket but they do real well.

Rita Ladany Fri, 11/01/2013 - 18:13

I planted my garlic the beginning of Oct and it is now sprouting. Should I trim the greens or just let them freeze and die out? Live, Love, & Laugh, Rita
