How To Grow Garlic At Home: From Planting to Harvest

Growing garlic at home is easy, even if you have a small garden. You do not need a large space or special gardening tools. You can grow garlic in garden beds, pots, or containers on a balcony. With the right soil, enough sunlight, and regular care, you can grow fresh garlic at home.

Garlic is a useful plant for any home garden. Its bulbs add flavor to many dishes, and its green leaves are also used in cooking. You can grow garlic from cloves purchased from a grocery store or saved from your previous harvest. Each clove grows into a new garlic plant.

Garlic grows best when planted during the cooler months. It needs well-drained soil and at least six hours of sunlight each day. Garlic takes 8 to 10 months to reach full maturity from fall planting to summer harvest, although softneck varieties in warmer climates mature in 3 to 5 months. In this guide, you will learn:

Garlic Types

Before you plant, you need to pick a type. There are two main kinds of garlic: hardneck and softneck.

Hardneck Garlic

Grows a stiff stem in the middle of the bulb
Makes a “scape,” a curly flower stem you can cook and eat
Handles cold winters very well
Has a bold, rich flavor
Stores for about 4 to 6 months

Softneck Garlic

Has a soft, bendy stem, which makes it good for braiding
Does not make scapes
Grows best in mild winters
Has a milder flavor
Stores for 8 to 12 months

Comparison

Parameters	Hardneck	Softneck
Best climate	Cold winters	Mild winters
Flavor	Bold and rich	Mild
Scapes	Yes	No
Storage time	4–6 months	8–12 months
Braiding	Not good for it	Great for it

Which One Garlic To Choose?

If your winters are cold, pick hardneck. If your winters are mild, pick softneck.

When to Plant Garlic

Fall Is the Best Time

Plant garlic in fall, about 4 to 6 weeks before the ground freezes. This gives the cloves time to grow roots before winter. They then rest through the cold and start growing again in spring.

If you plant too early, the cloves send up leaves before winter and can get damaged by frost. If you plant too late, the roots won’t have time to settle in.

A good sign is when the soil has cooled down to about 60°F (15°C) or lower.

Planting Garlic Times by USDA Zone

USDA Zone	Best Time to Plant
Zones 3–4	Late September to early October
Zones 5–6	Early October to early November
Zones 7–8	Late October to November
Zones 9–10	November to December

These dates are a guide. Your own local frost date matters, so count back 4 to 6 weeks from it.

Warm climates (zones 9–10): Garlic needs some cold to form good bulbs. Put your seed garlic in the fridge for 4 to 8 weeks before planting, and choose softneck varieties.

Can You Plant Garlic in Spring?

Yes, but the results are not as good. Spring-planted garlic gives smaller bulbs because it gets less time to grow.

Choosing Garlic Cloves

Buy Seed Garlic

For the best results, buy seed garlic from a garden center, farm, or online seed shop. Here’s why:

It is disease-free, so it won’t bring problems into your soil
It is a variety suited to home growing
It sprouts more reliably

Garlic from the grocery store is often treated to stop it sprouting. It can still grow, but the results are less reliable.

What to Look For

Large, firm, plump bulbs
No soft spots, mold, or dark marks
Dry, papery skin that is still on the bulb

Preparing Your Cloves for Planting

Split the bulb into cloves a day or two before planting. Do this by hand, and keep the papery skin on each clove.
Choose the biggest cloves. Large cloves grow into large bulbs. Save the small ones for cooking.
Throw away any damaged cloves. Skip any that are soft, shriveled, or moldy.
Plant the same day you split them, or within a day or two. Don’t leave them out for long.

Optional tip: Some gardeners soak the cloves for a few hours in water mixed with a little liquid seaweed before planting. This isn’t required, but it can help them get started.

Where to Plant Garlic: Sun and Soil

Sunlight

Garlic needs full sun, at least 6 to 8 hours of direct sunlight each day. In shade, the plants grow slowly and the bulbs stay small.

Soil

Garlic likes soil that is loose, rich, and drains well. Heavy, soggy soil makes the cloves rot.

Soil type: Loose and crumbly. Sandy loam is ideal.
Soil pH: Between 6.0 and 7.0 is best.
Before planting: Mix in 2 to 3 inches of compost or well-rotted manure. This feeds the plants through the season.
Drainage: If water sits on your soil after rain, plant in a raised bed or on a small mound.

Tip: Don’t plant garlic where onions, leeks, or garlic grew in the last 2 to 3 years. This helps stop soil diseases from building up.

Growing Garlic in Containers

You can grow garlic in pots. Here’s what to use:

A pot at least 10 to 12 inches deep, with drainage holes
Good quality potting mix with some compost
A sunny spot that gets 6 to 8 hours of light

Containers dry out faster than garden beds, so check the soil often.

How to Plant Garlic

Prepare the bed
Loosen the soil about 8 inches deep. Remove weeds and rocks, then mix in compost.

Make the planting holes.
Each hole should be about 2 inches deep. In colder areas, go a little deeper, about 3 inches, to protect the cloves from frost.

Space the cloves.
Place cloves 4 to 6 inches apart. If you plant in rows, leave 10 to 12 inches between the rows.

Plant with the pointy end up.
The flat, root end goes down. If the clove is planted upside down, the shoot has to twist its way up, and the plant grows weaker.

Cover and press down gently.
Fill the holes with soil, then pat the surface lightly.

Water well.
Give the bed a deep watering to help the roots settle in.

Add mulch.
Spread 4 to 6 inches of straw, shredded leaves, or dry grass clippings over the bed. Mulch protects the cloves from freezing, keeps the soil moist, and stops weeds.

Garlic Care During the Season

Watering

Fall: Water after planting so the roots can settle. After that, rain is usually enough.
Winter: Garlic needs little or no extra water while it rests.
Spring and early summer: This is when the bulbs grow. Give about 1 inch of water per week, including rain. Water deeply instead of a little each day.
Before harvest: Stop watering about 2 to 3 weeks before harvest. Dry soil helps the bulbs mature and store well.

Feeding

Garlic is a hungry plant. Give it a boost in early spring, when the green shoots begin to grow fast.

Use a nitrogen-rich fertilizer, such as blood meal, fish emulsion, or compost tea
Feed again about 3 to 4 weeks later
Stop feeding by late spring (around the end of May in many areas). Feeding too late can lead to small, poorly formed bulbs.

Weeding

Garlic does not compete well with weeds. Keep the bed clear, especially in spring. Pull weeds by hand, or use a shallow hoe, because the roots are close to the surface.

Cutting Scapes (Hardneck Garlic Only)

In late spring or early summer, hardneck garlic sends up a curly flower stem called a scape.

Cut it off when it curls once or twice, before it straightens. This sends the plant’s energy into the bulb instead of the flower, so you get bigger bulbs.
Don’t throw the scapes away. They taste mild and garlicky. Use them in stir-fries, pesto, soups, or grilled on their own.

Common Problems and Fixes

Problem	Likely Cause	What to Do
Yellow leaves in spring	Nitrogen, or soil too wet	Feed with a nitrogen fertilizer, and improve drainage
Yellow tips in early summer	Natural ripening	No action needed. This is normal near harvest.
Small bulbs	Crowding, weeds, little water in spring, or small cloves planted	Space plants properly, weed often, water in spring, plant big cloves
No bulb forming	Planted too late, too little cold, or too much shade	Plant in fall, give it full sun, and chill seed garlic first in warm areas
Rust (orange spots on leaves)	Fungus in cool, damp weather	Remove badly affected leaves, space plants for airflow, and avoid watering from above
White rot (white fuzzy mold on bulbs, yellowing leaves)	Soil fungus that is hard to remove	Pull and throw away affected plants (not in compost), and don’t grow garlic or onions in that spot for several years
Onion maggots or other pests	Flies laying eggs near the plants	Cover plants with row cover, and rotate crops each year
Aphids	Small sap-sucking insects	Spray off with water, or use insecticidal soap

Preventing Most Problems

A few habits stop garlic problems before they start:

Buy disease-free seed garlic
Plant in well-draining soil
Rotate crops. Don’t plant garlic in the same spot two years in a row.
Keep the bed weed-free
Give plants enough space so air can move between them

When and How to Harvest Garlic

When Is Garlic Ready?

Garlic is usually ready in mid-summer, about 8 to 9 months after fall planting. In many areas this falls between late June and August.

Watch the leaves. Harvest when:

The lower 3 to 4 leaves have turned brown and dry
The top 5 to 6 leaves are still green

Each leaf stands for one layer of paper wrapping around the bulb. If you wait until all the leaves are brown, the wrapping splits and the bulb stores poorly. If you pick too early, the bulbs are small and the cloves are not fully formed.

Tip: Dig up one test bulb first. The bulb should be full, with cloves that fill out their papery skins.

How to Harvest

Stop watering 2 to 3 weeks before harvest, and pick a dry day.
Loosen the soil around the plants with a garden fork or spade, a few inches away from the bulbs.
Lift the bulbs gently. Don’t pull them by the stem, because it can snap off.
Brush off loose soil with your hand. Don’t wash the bulbs, and don’t knock them around, because bruised bulbs rot faster.
Keep the leaves and roots on for now. They help the bulbs dry.

Curing and Storing Garlic

Curing

Curing means drying the garlic so it lasts months in storage. It takes 2 to 4 weeks.

Tie the plants in small bunches of 5 to 10, or lay them in a single layer on a rack
Hang or place them in a dry, shaded, airy spot, such as a porch, garage, or shed
Keep them out of direct sun and rain
Garlic is cured when the outer skins feel papery, the roots are dry and stiff, and the stem is dry and hard when you cut it near the bulb

Cleaning and Trimming

Cut the roots to about 1/4 inch
Cut the stems to about 1 inch for hardneck garlic. For softneck garlic, you can leave the stems on and braid them.
Rub off dirt gently, and leave the papery layers on

Storing

The best conditions are cool, dry, and dark with some airflow, around 60–65°F (15–18°C).

Use mesh bags, baskets, or paper bags
Don’t use plastic bags or airtight containers, because they trap moisture
Don’t store in the fridge, as it can make the cloves sprout

Type	How Long It Keeps
Hardneck	About 4–6 months
Softneck	About 8–12 months

Check your stored garlic now and then, and use up any bulbs that go soft or start sprouting.

Save Seed Garlic for Next Year

Set aside your biggest, healthiest bulbs and plant them in fall. Over a few years, your garlic gets better suited to your garden. You don’t need to buy seed garlic again.

FAQs

Can I grow garlic from a grocery-store clove?
Yes, it sprouts. But store-bought garlic may be treated to stop sprouting, and it can carry diseases. For the best results, buy seed garlic.

Can I grow garlic indoors or in pots?
Yes. Use a pot at least 10 to 12 inches deep, in a spot with 6 to 8 hours of sun. Outdoor pots usually work better than indoor ones, since garlic needs a cold rest period.

How long does garlic take to grow?
About 8 to 9 months from fall planting to summer harvest.

Why did my garlic not form bulbs?
Common reasons are planting too late, too little cold, too much shade, too much nitrogen late in the season, or crowded plants.

Is garlic an annual or perennial?
Garlic is a perennial plant, but gardeners grow it as an annual. Plant it, harvest it, and plant again the next fall.

Can I eat garlic leaves and scapes?
Yes. Young green garlic leaves and scapes both taste mild and garlicky, and are good in cooking.

Conclusion

Growing garlic is simple. Plant good cloves in fall, give them sun and loose soil, mulch for winter, feed them in spring, and harvest in summer. After that, dry them well and they last for months.
