Garlic is easy to grow and produces numerous bulbs after a long growing season. It is frost tolerant. Beyond its intense flavor and culinary uses, “the stinking rose” is good in the garden as an insect repellent and has been used for centuries as a home remedy.

Planting

  • Garlic can be planted in the spring as soon as the ground can be worked, but fall planting is recommended for most gardeners. Plant in the fall and you'll find that your bulbs are bigger and more flavorful when you harvest the next summer.
  • In areas that get a hard frost, plant garlic 6 to 8 weeks before that frost. In southern areas, February or March is a better time to plant.
  • Break apart cloves from bulb a few days before planting, but keep the papery husk on each individual clove.
  • Plant cloves about one month before the ground freezes. 
  • Do not plant cloves from the grocery store. They may be unsuited varieties for your area, and most are treated to make their shelf life longer, making them harder to grow. Instead, get cloves from a mail order seed company or a local nursery.
  • Ensure soil is well-drained with plenty of organic matter. Select a sunny spot.
  • Place cloves 4 inches apart and 2 inches deep, in their upright position (the wide root side facing down and pointed end facing up).
  • In the spring, as warmer temperatures come, shoots will emerge through the ground.

Care

  • Northern gardeners should mulch heavily with straw for overwintering.
  • Mulch should be removed in the spring after the threat of frost has passed. (Young shoots can't survive in temps below 20°F on their own. Keep them under cover.)
  • Cut off any flower shoots that emerge in spring. These may decrease bulb size.
  • Weeds should not be a problem until the spring. Weed as needed.
  • Garlic requires adequate levels of nitrogen. Fertilize accordingly, especially if you see yellowing leaves.
  • Water every 3 to 5 days during bulbing (mid-May through June).
  • A note on garlic scapes: Some folks love cooking the scapes (the tops of hardneck garlic). Whether you trim the scapes or let them keep growing is your preference. We like to stir fry scapes the way we cook green beans—similar with a spicy kick!

Pests

Garlic has very few problems with pests in the garden (in fact, its a natural pest repellent!), and also very few problems with the diseases that plague other veggies. White Rot is one concern, but you should also keep an eye out for the same pests that plague onions.

  • White Rot is a fungus that may attack garlic in cool weather. Not much can be done to control or prevent that problem except rotating your crops and cleaning up the area after harvesting. The spores can live in the soil for many years. The fungus affects the base of the leaves and roots.

Harvest/Storage

  • Harvest time depends on when you plant, but the clue is to look for yellow tops. Harvest when the tops begin to yellow and fall over, before they are completely dry.
  • In Northern climates, harvesting will probably be in late July or August. In Southern climates, it will depend on your planting date.
  • Check the bulb size and wrapper quality; you don't want the wrapper to disintegrate. Dig too early and the bulb will be immature. Discontinue watering.
  • To harvest, carefully lift the bulbs with a spade or garden fork. Pull the plants, carefully brush off the soil, and let them cure in an airy, shady spot for one to two weeks. We hang them upside down.
  • The bulbs are cured and ready to store when the garlic skins are papery and the roots are dry. The root crown should be hard, and the cloves can be cracked apart easily.
  • Garlic bulbs may be stored individually with the tops removed, or the dried tops may be braided together to make a garlic braid to hang in the kitchen or storage room.
  • Bulbs should be stored in a cool (40 degrees F), dark, dry place, and can be kept in the same way for several months. Don't store in your basement if it's moist!
  • The flavor will increase as the bulbs are dried.
  • If you plan on planting garlic again next season, save some of your largest, best-formed bulbs to plant again in the fall.

Recommended Varieties

There are three types of varieties of garlic: Softneck, Stiffneck, and Great-headed (Elephant). Most types are about 90 days to harvest.

  • Softneck varieties, like their name suggests, have necks that stay soft after harvest, and therefore are the types that you see braided. Especially recommended for those in warmer climes, as it is less winter-hardy than other types. Strong, intense flavor. Recommended varieties: 'Persian Star', 'Mother of Pearl'
  • Stiffneck varieties grow one ring of cloves around a stem, there is not a layer of cloves as there are in softneck varieties. They are extremely cold hardy, but do not store as well or long as other varieties. Flavor is more mild than softnecks. Recommended Variety: 'Carpathian'
  • Great-headed varieties are not recommended. They are less hardy, and more closely related to leeks than other varieties. Their flavor is more like onion than traditional garlic. Bulbs and cloves are large, with about 4 cloves to a bulb.

Thank you for an interesting

By L. Thielen on June 18

Thank you for an interesting site. When we harvest our garlic the dense dirt insists on clinging to the sides and they never look clean like store-bought garlic. It seems that washing the dirt off would be a mistake. What do you advise? Thanks.

You have the right instincts.

By Almanac Staff on June 18

You have the right instincts. Homegrown garlic will still be on the dirty side compared to store-bought. After harvesting, you want to "cure" the garlic by letting it dry in a protected place out of the sun that's warm but not hot nor moist. When the outer skin gets papery, brush off as much dirt as you can and cut the roots. We do not wash it prior to storage. Further cleanup or washing the garlic may shorten its lifespan. If the dirt is bothersome to you, remove the outer layer of wrapper. We hope this advice helps.

By Almanac Staff on June 10

Yes, you can grow garlic in a container. We really think it's best if they grow outside. They root in the cold of winter. The warm indoor temperatures won't allow them to grow properly.

I planted garlic last spring

By Gail Batten on June 1

I planted garlic last spring and it never came up but I never dug up the "lost" garlic and to my suprise when I uncovered the bed this spring there it was up 6 inches. Is there anything I need to worry about since it has been in the ground so long? The stem are large and seem to be hardy. I have never growen it before but buying localy grown garlic and because they longer compared to the store bought bulbs made me want to grow it. I know the one is Elephant garlic and I can't remember the other. Any insight you can give me would be helpful on my first garlic grow.

Your garlic should be

By Almanac Staff on June 11

Your garlic should be suitable for consumption. The heads may be on the small side, but still delicious. When the leaves start to decline, stop watering. Harvest when several of the lower leaves go brown, but five or six on top are still green.

My question is concerning the

By lrobinson2011 on May 27

My question is concerning the flowering portion of the garlic. I planted garlic for the first time in the fall of 2012. But, due to my lack of knowledge and research I allowed the garlic to stay in the ground too long and it is now flowering. Can I cut off the flower end if it bulbs and plant it? I don't have much knowledge about garlic but someone was telling me that I could cut off the ends and plant them. Any advice or know anyone is willing to share would be great thanks.

Yes, you can plant the small

By Almanac Staff on May 30

Yes, you can plant the small bulbils that are found inside the flower. Cut off the stalks with the flower heads attached. Tie the stalks together in bunches and hang them upside down in a ventilated area to dry. When dry plant the individual small bulbils in the fall and add mulch if you have severe winters. Next spring dig the small bulbs, dry and replant the tiny cloves in the fall. It takes several years to grow full-size bulbs.

I'm enthralled with "A Garlic Testament" by Stanley Crawford....seasons and growing garlic on a small New Mexico farm....a great mixture of gardening tips and philosophy ...Aldo Leopold on garlic. This is not a commercial...just wanted to share this title.

garlic scapes/sticky cloves

By Anonymous

Maybe it's the variety, but I missed a few scapes last summer and did not notice a difference in bulb size...for what it's worth.

My question, it's Sept 29 and I'm planting my cloves. One variety I bought from a local farmer the cloves are almost stuck together, a little sticky/funky...should I NOT plant them? Just that one variety, from that one farm. (I've others from other seed places, and some from my garden from last year, planting about 6 varieties this year) I planted them anyway, but am worried about bringing rot or fungus into my garden.

Seeds from scapes?

By Anonymous

I let one of my scapes grow longer just to see what happens and it made a bunch of little seeds in the scape. Are these plantable?

garlic 'scape' seeds.

By Anonymous

It is my understanding that YES the 'seeds' from the scape are plantable...however you need to give them 2 years to mature...I've read that you plant them year 1, dig them out, and replant year 2 for bigger heads. I've planted 2 rows this year for the first time...we'll see.

can you plant the seeds from

By Anonymous

can you plant the seeds from the flower head and get more garlic or will they just die?

Garlic doesn’t produce

By Almanac Staff

Garlic doesn’t produce flowers or seeds. The individual cloves from heads of garlic are separated and planted. Do not plant grocery store garlic. Find garlic from a gardener friend or local farmer. Individual cloves should be planted, pointed-side up, 2 to 3 inches deep. Each clove will become an entire head of garlic!

correction

By Anonymous

garlic does produce both flowers and seeds, but it is much easier to clone the bulbs, so seed isn't commonly sold. the seeds look just like onion seeds, and the scape will grow a flower head if left to do so.

Store bought garlic

By Anonymous

I just wanted to letyou know that I planted store bought garlic and I have had good results in their production. The stalks are large,no fungus,green scapes and they are not yellowing as yet.I plan to leave them till June or July before I harvest them .I did ammend the soil before planting and gave them some 10=10=10 in the winter well covered with compost and straw mulch.I paid 79 cents for a large head and planted the large outer cloves in October. Hope to share my crop with my friends who have seen my good results to my sixty to seventy heads growing until harvest.

First time planting

By Anonymous

I haven't planted garlic before, and I planted some in May when I planted the rest of my vegetable garden in southeast Michigan. I am now learning that garlic is to be planted in the Fall. However, I have garlic plants that are about 5 inches tall now. Should they be harvested this year or should I let them stay in ground over winter?

Since it is OK to plant

By Almanac Staff

Since it is OK to plant garlic in the Spring, you can safely harvest them when they are ready. Generally, garlic planted in Spring should be ready for harvest by late-July or early August. You'll want to pay attention to when the tops yellow and begin to fall over.

If you'd like, you can plant again in the Fall! It's been noted that planting in the Fall MAY produce bigger and better bulbs. Read above for more info on Fall planting.

Thank you for your interest in the Old Farmer's Almanac and our Web site.

If scapes don't appear?

By Anonymous

If scapes are not showing up, is there a problem, or do you just wait longer?

garlic scapes

By Almanac Staff

The scape appear a month or so after the first leaves so maybe it's a waiting game. Also, not all garlic varieties have scapes. Scapes form only on Hardneck varieties.

Don't pitch the scapes!

By JBL55

The first time I planted garlic, I cut off the scapes (what this article calls "flower shoots") when they appeared and threw them on the compost heap. A few weeks later I learned they can be used in cooking. Auggghhh! After I dried my tears, I began to look for garlic scape recipes and in the years since have had great fun with scapes (e.g. pesto).

If left to mature, the scapes will make the plant think it's successfully reproduced so, as the article states, the bulb will not be as robust as it might. However, it's fun to let one or two mature so you can see the teeny tiny "head" of garlic seeds that will develop.
