Can You Grow Garlic from Garlic?

Yes, you can absolutely grow garlic from a garlic bulb you already have. A single clove, when planted in the right soil and season, will grow into a full new head of garlic. However, not every grocery-store bulb works well – choosing the right garlic and planting it correctly makes the difference between a tiny bulb and a big, flavorful harvest.

What kind of garlic should you plant?

There are two main types of garlic: softneck and hardneck. Softneck garlic is the common type found in most supermarkets. It has a soft, pliable stem, stores for many months, and produces many small cloves per head. Hardneck garlic has a stiff central stalk (called a scape), fewer but larger cloves, and a richer, more complex flavor. Hardneck varieties are often better for colder climates.

For the best results, buy seed garlic from a garden center or a trusted online farm. Seed garlic is certified disease-free and grown specifically for planting. It costs more than grocery garlic but gives you a much higher success rate and bigger bulbs.

If you want to experiment, you can still use garlic from the store – just understand you might get smaller or fewer bulbs.

Can you use garlic from the grocery store?

Technically, yes, you can plant cloves from a grocery-store garlic bulb. But there are risks. Many store-bought bulbs are treated with growth inhibitors or even bleach to prevent sprouting during shipping and storage. These treatments can stop the clove from growing at all, or produce very weak plants.

Also, grocery garlic is often grown in a different region or even another country. It may carry soil-borne diseases like white rot or nematodes that can infect your garden soil for years. And many store bulbs are softneck varieties that perform poorly in cold winters.

If you decide to try grocery garlic anyway, choose bulbs that are organic (less likely to be treated), firm, and already starting to sprout a tiny green tip. The ones that are already sprouting have a higher chance of growing.

When is the best time to plant garlic?

Garlic is a cool-season crop. In most climates, the best planting time is fall, about 4–6 weeks before the ground freezes. This gives the clove time to grow roots but not shoots. The clove lies dormant over winter and then starts growing early in spring.

For warmer climates (zones 7–9), you can plant garlic in late fall or early winter. For very cold areas, you may need to plant in early fall and mulch heavily. Some gardeners in mild winter areas plant garlic in late winter for a summer harvest, but fall planting usually produces the biggest bulbs.

A simple rule: plant garlic after the first frost but before the ground becomes hard to dig.

How do you prepare garlic cloves for planting?

Start by carefully breaking apart the garlic head into individual cloves. Do not peel the papery skin off each clove – that skin protects the clove from rot and pests. Choose the largest cloves from each head for planting; small cloves produce small bulbs.

If you are using seed garlic, it’s ready to plant as is. If you are using grocery garlic, you can soak the cloves in a solution of baking soda and water (1 tablespoon per quart) for 2 hours to help reduce the risk of fungal disease. Rinse, then plant immediately.

Do not refrigerate garlic before planting – it needs a period of cold naturally from the soil, not the fridge.

What is the best soil and location for growing garlic?

Garlic needs full sun – at least 6–8 hours of direct sunlight each day. The soil should be loose, well-draining, and rich in organic matter. Heavy clay or compacted soil will cause bulbs to rot or grow misshapen.

Before planting, mix in a 2-inch layer of compost or well-rotted manure. You can also add a balanced organic fertilizer (such as 10-10-10) according to package directions. A soil test can tell you if you need extra phosphorus or potassium – garlic is a heavy feeder.

If you are growing in containers, choose a pot at least 12 inches deep and wide. Fill with high-quality potting mix blended with compost.

A simple soil test kit can tell you exactly what your soil needs.

How deep and far apart should you plant garlic?

Plant each clove 2 inches deep (measure from the tip of the clove to the soil surface) in northern climates, or 1 inch deep in warmer areas where the ground stays warmer. The pointed end should face up, and the flat root end should face down.

Space the cloves 6 inches apart in rows that are 12 inches apart. This gives each plant enough room to develop a full bulb. If you plant too close, the bulbs will be small.

After placing the clove in the hole, cover with soil and water thoroughly once. Then spread a layer of mulch (straw, chopped leaves, or grass clippings) about 3–4 inches deep. Mulch keeps the soil moist, suppresses weeds, and protects the cloves over winter.

How do you care for garlic as it grows?

In spring, when you see green shoots emerging, remove some of the mulch so the shoots can reach sunlight. Keep the soil consistently moist but not soggy. Garlic needs about 1 inch of water per week during spring and early summer. Stop watering completely once the leaves start to yellow in mid-summer – that signals the bulb is finishing growth.

Weed carefully – garlic does not compete well with weeds. Hand-pull or very shallowly hoe weeds to avoid damaging the shallow roots.

If you grow hardneck garlic, it will produce a curly green flower stalk called a garlic scape in early summer. Cut off the scape as soon as it curls – this directs all the plant’s energy into making a bigger bulb. You can eat the scapes (they taste like mild garlic) or compost them.

For softneck varieties, you can leave the flower stalk; it won’t affect the bulb much, but it will make braiding later easier.

Fertilize once more in early spring with a balanced fertilizer or fish emulsion to support leaf growth. Stop fertilizing after the scape appears.

When and how do you harvest garlic?

Garlic is usually ready to harvest in mid- to late summer, depending on when you planted. Look for these signs:

• The lower leaves turn brown and dry.
• About half of the leaves are still green.
• The bulb feels firm and the skin is papery.

Do not wait until all leaves are dead – overripe garlic will split open and rot in storage. Gently dig up one test bulb to check if the cloves are fully separated and the skin is tight.

To harvest, use a garden fork or trowel to loosen the soil around the bulb, then pull the whole plant by the stem. Do not yank the stem or it may break off from the bulb.

A sturdy garden trowel makes it much easier to lift bulbs without damage.

How do you cure and store homegrown garlic?

After harvesting, garlic needs to cure (dry) so it can last for months. Do not wash the bulbs – just brush off loose soil. Leave the stems and roots attached.

Bundle 6–8 plants together and hang them upside down in a warm, dry, well-ventilated place out of direct sunlight. A garage, shed, or covered porch works well. Let them cure for 2–4 weeks, until the neck (where the leaves meet the bulb) is completely dry and papery.

Once cured, cut off the stems leaving about 1–2 inches of stem above the bulb. Trim the roots to about ¼ inch. Store the bulbs in a cool, dark, dry place (60–70°F / 15–21°C) with good air circulation. Mesh bags, paper bags, or open baskets all work. Do not store in plastic – it traps moisture and causes rot.

Softneck garlic stores for 6–8 months. Hardneck garlic stores for 3–5 months. Save your biggest, best-looking bulbs to replant next season.

What are common problems when growing garlic from garlic?

Here are the most frequent issues and simple solutions:

If you see rust-colored spots on leaves (garlic rust), remove affected leaves and improve air circulation. Avoid overhead watering. For nematodes (tiny worms that stunt growth), you may need to stop planting alliums in that spot for several years and consider solarizing the soil.

The best way to avoid most diseases is to start with certified disease-free seed garlic and practice crop rotation – don’t plant garlic where onions, leeks, or other alliums grew the previous year.

If you want to take your garlic growing to the next level, consider a garlic planter dibber tool to get perfect depth and spacing every time – it saves your back and speeds up planting a big patch.

Growing garlic from a clove is one of the most rewarding garden projects. With the right timing, soil, and care, a single clove can give you a whole head of fresh, flavorful garlic that tastes far better than anything from the store. Whether you start with grocery-store bulbs or high-quality seed garlic, the process is simple and the payoff is delicious. Plant some this fall and you will be pulling up your own garlic next summer.
