How to Grow Garlic in a Pot: The Complete Beginner’s Guide
Learning how to grow garlic in a pot is one of the most rewarding projects in apartment gardening — and one of the most overlooked. Most people assume garlic needs a vegetable bed and a full garden to produce well. It does not.
A single terracotta pot on a sunny balcony or windowsill produces fresh garlic greens within weeks and full bulbs within months. Growing garlic in pots gives you complete control over soil quality, drainage, and position — advantages that in-ground gardeners simply do not have.
This guide covers everything: the right pot, the right variety, planting depth, watering, feeding, and exactly when to harvest — whether you are growing for greens, scapes, or full bulbs.
What you can harvest from pot-grown garlic
Garlic greens — snip from shoots 6 to 8 inches tall. Ready in 3 to 4 weeks. Use like chives in any recipe.
Garlic scapes — the curling flower stems hardneck varieties produce in late spring. Harvest when curled, use like mild garlic in cooking.
Garlic bulbs — the full harvest. Takes 6 to 9 months from planting. Smaller than garden-grown but equally flavourful.
What You Need to Grow Garlic in a Pot
🪴 The pot
Minimum 6 to 8 inches deep with drainage holes. Deeper is better — 10 to 12 inches produces larger bulbs. Terracotta or plastic both work.
🧄 The garlic
Use seed garlic from a garden centre or nursery, not supermarket bulbs — most are treated to prevent sprouting. Break into individual cloves, keep papery skin on.
🌱 The soil
Well-draining potting mix enriched with compost. Add a handful of perlite or coarse sand per pot for extra drainage — garlic rots in waterlogged soil.
☀️ The light
At least 6 hours of direct sunlight per day. A south-facing windowsill or balcony is ideal. If light is limited, garlic greens still grow but bulbs will be small.
Hardneck vs Softneck — Which Variety to Grow in Pots
This is the first decision to make when growing garlic in a pot, and it depends almost entirely on your climate.
| Type | Best Climate | Bonus Harvest | Bulb Size | Storage |
|---|---|---|---|---|
| Hardneck | Cold winters (Zone 7 and below) | ✅ Garlic scapes in spring | Large cloves, fewer per bulb | 3–6 months |
| Softneck | Mild winters (Zone 8 and above) | ❌ No scapes | Smaller cloves, more per bulb | 6–12 months |
If you want to grow garlic indoors at any time of year, softneck varieties are your best bet — they grow well in mild, stable conditions. Hardneck garlic prefers a colder environment to form cloves properly. If your climate is cold, give cloves a simulated winter before planting — place them in the refrigerator (not freezer) for 2 to 4 weeks to trigger proper bulb development.
How to Grow Garlic in a Pot — Step by Step
Prepare your pot and soil
Fill your pot with well-draining potting mix mixed with a handful of perlite or coarse sand for extra drainage. Leave 2 to 3 inches of space below the rim. If you have homemade compost from your worm bin, mix a small amount into the top layer — apartment compost is particularly well-suited to container garlic.
Separate and prepare the cloves
Break your garlic bulb into individual cloves. Keep the papery skin on each clove — it protects against infection. Discard any cloves that are soft, damaged, or significantly smaller than the rest. The largest cloves produce the largest bulbs.
Plant the cloves
Dig small holes just about the same depth as each clove is long — approximately 1 to 2 inches deep — spaced four inches apart. Place one clove inside each hole with the pointed side facing upwards. Roots will grow out of the bottom of the clove, so make sure the flat end goes down and the pointed tip faces up. Cover loosely with soil and water thoroughly.
Position in full sun
Place your pots in a south-facing window where they will receive at least 6 hours of sunlight daily. If natural light is insufficient, supplement with a grow light for vegetables positioned 6 to 12 inches above the plants for 12 to 14 hours per day. Rotate your pots a quarter turn every few days to prevent the shoots from leaning toward the light source.
Water correctly
Garlic wants consistent moisture but does not like wet feet. Check your pots often and water when the top couple of inches of soil feels dry. Good drainage is key — your container should never hold water in the bottom. In winter, reduce watering significantly as the plant is dormant.
Harvest garlic greens as they grow
For garlic greens, you can start snipping once the shoots are about 6 to 8 inches tall. These tender greens are flavourful and perfect for tossing into salads, stir-fries, or scrambled eggs. Just be sure not to cut more than a third of the greens at once so the plant can continue to grow. This harvest starts within 3 to 4 weeks of planting.
Snap off garlic scapes (hardneck only)
In early summer, hardneck garlic varieties will produce a scape — a curly flower stalk. Snap the scape off to divert the plant's energy into growing a bigger bulb. Do not discard the scapes — they taste like mild garlic and work beautifully in stir-fries, pesto, and pasta.
Harvest the bulbs
Let the plants grow until the foliage is about 50% yellow — at which point it is time to harvest. Dump out the pot and unearth the heads of garlic. Cure the bulbs in a dry, well-ventilated spot for 2 to 3 weeks before storing. Softneck varieties store for up to 12 months. Hardneck varieties store for 3 to 6 months.
When to Plant Garlic in a Pot
Timing depends on whether you are growing for greens or bulbs.
- For full bulbs — plant in autumn. Plant your garlic in the fall after the first frost — the soil is cooled but nothing is frozen. Depending on where you live, that means planting between September and November. The bulbs develop roots in autumn, go dormant in winter, and grow vigorously through spring for a summer harvest.
- For garlic greens only — plant any time. If you only want snippable green shoots rather than full bulbs, you can plant cloves indoors at any time of year. Greens appear in 3 to 4 weeks regardless of season as long as you have adequate light.
- For spring planting of bulbs — softneck varieties planted in spring will produce smaller bulbs in about 90 days. Chill the cloves in the fridge for 2 to 4 weeks before spring planting to simulate the cold period they need.
How Many Cloves Fit in a Pot?
| Pot Size | Depth | Cloves per Pot | Best For |
|---|---|---|---|
| 6 inch pot | 6–8 inches | 1–2 cloves | Greens only |
| 8–10 inch pot | 8–10 inches | 3–4 cloves | Greens and small bulbs |
| 12 inch pot | 10–12 inches | 6–8 cloves | Full bulbs Recommended |
| 5 gallon bucket | 12+ inches | 8–12 cloves | Maximum yield |
Common Problems When Growing Garlic in Pots
Yellowing leaves early in the season. Almost always overwatering or poor drainage. Check that water is flowing freely from the drainage holes and reduce watering frequency before assuming a nutrient problem.
No shoots after 3 weeks. Either the cloves were planted flat-end up rather than pointed-end up, or the garlic was treated and will not sprout. Dig one clove carefully to check — a healthy clove will show a small white root tip forming at the base.
Small or undeveloped bulbs at harvest. Most commonly caused by insufficient pot depth, too much heat during bulb development, or harvesting too early. The plant will start to form bulbs underground once the soil starts to warm up in spring, but if the soil gets too hot, bulbs can stop growing before their time, leaving you with small or underdeveloped bulbs. Move pots to a slightly cooler position in late spring if temperatures are spiking.
Bulbs not forming separate cloves. This happens when hardneck varieties do not get enough cold exposure during winter. Next season, refrigerate cloves for 2 to 4 weeks before planting, or plant earlier in autumn to ensure adequate cold time before spring growth begins.
Frequently Asked Questions
Can I grow garlic in a pot indoors all year round?
Yes — for garlic greens. If you only want the fresh green shoots to use like chives, you can plant cloves indoors at any time of year with no cold period required. For full bulbs, you need either a natural cold season outdoors or a 2 to 4 week refrigerator chill before planting.
Can I use garlic from the supermarket to grow in a pot?
Sometimes, but it is unreliable. Most supermarket garlic is treated with a sprout inhibitor to extend shelf life. Some cloves will still sprout but many will not. For reliable results when growing garlic in pots, buy seed garlic from a garden centre or nursery — it is untreated and bred for growing.
How long does it take to grow garlic in a pot?
Garlic greens are ready to snip in 3 to 4 weeks. Garlic scapes appear in late spring (hardneck varieties only). Full bulbs take 6 to 9 months from autumn planting to summer harvest. If you want faster results, grow for greens first while your bulbs develop underground.
Do I need to water garlic in a pot differently from herbs?
Yes. Garlic is more sensitive to overwatering than most herbs. Water only when the top 2 inches of soil feel dry — not on a fixed schedule. In winter when the plant is dormant, reduce watering to once every 2 to 3 weeks. Garlic rots quickly in waterlogged soil, so drainage is more important than water frequency. Our windowsill herb garden guide covers general watering principles for container growing that apply here too.
What is a garlic scape and what do I do with it?
A garlic scape is the curling green flower stem that hardneck garlic varieties produce in late spring. Snap it off when it curls — this redirects the plant's energy into bulb growth rather than flowering, which produces a larger harvest. The scape itself tastes like mild fresh garlic and can be used in stir-fries, pesto, pasta, and roasted vegetable dishes. It is one of the bonus harvests you only get from growing garlic in pots rather than buying it.
Can I grow other things alongside garlic in the same pot?
Yes — with the right companions. Garlic grows well alongside most herbs and acts as a natural pest deterrent for nearby plants. Avoid planting garlic near beans or peas in the same container — garlic releases compounds that inhibit their growth.
