Did you know you can grow garlic in pots and enjoy fresh bulbs right from your balcony or patio? It’s easier than you think, and the rewards are worth it. With just a bit of planning and care, you can harvest flavorful, homegrown garlic even without a backyard garden. Let’s dive in.
Why Grow Garlic in Pots?
Growing garlic in containers has several advantages. First, it gives you control over soil quality, which is crucial for healthy garlic. Containers also offer better drainage, which garlic loves. Plus, if you live in a colder area, you can move pots indoors or into a sheltered spot to protect your plants during harsh weather. Finally, container garlic growing is perfect for people with limited space — urban gardeners, apartment dwellers, or anyone with a small patio.
Choosing the Right Garlic
Start with good seed garlic. This is garlic sold specifically for planting, not eating. Grocery store garlic is often treated to prevent sprouting, so it’s not a reliable choice.
There are two main types of garlic:
- Hardneck Garlic: Best for colder climates. Produces fewer but larger cloves and grows scapes (flowering stalks) you can also eat.
- Softneck Garlic: Thrives in milder areas. Produces more cloves per bulb and stores longer after harvest.
Pick the type suited to your climate. If you’re unsure, hardneck is a safe bet for most first-time growers because it’s hardy and forgiving.
Picking the Right Pot
Garlic needs space for its roots to spread and the bulb to grow. Choose a pot that is at least 8–12 inches deep and wide enough to allow spacing of about 4–6 inches between cloves. A wider pot lets you plant multiple cloves, creating a mini garlic garden.
Make sure your pot has good drainage holes. Garlic hates soggy roots. If necessary, drill a few extra holes at the bottom.
Materials like terracotta, fabric grow bags, or plastic all work, but terracotta tends to breathe better and prevents overwatering.
The Right Soil Mix
Garlic needs loose, nutrient-rich soil. Compacted or heavy soil leads to stunted bulbs. Use a high-quality potting mix blended with some compost. You want a mix that’s light and drains well but can still hold some moisture.
A good soil mix looks like this:
- 2 parts potting soil
- 1 part compost
- 1 part perlite or sand for drainage
Avoid garden soil from your yard—it’s often too dense for container growing and may bring pests or diseases.
Planting Garlic in Pots
Here’s how you plant garlic step-by-step:
- Break the bulb into individual cloves. Keep the papery skin on each clove.
- Plant each clove with the pointed end up and the flat end down. Plant them about 2–3 inches deep into the soil.
- Space the cloves about 4–6 inches apart.
- Cover the cloves with soil and gently firm it down.
- Water the soil until it’s evenly moist but not soaked.
Timing is important. Plant in fall if possible (September–November depending on your region). Garlic needs a cold period to form good bulbs. If fall planting isn’t an option, you can plant in very early spring, but your bulbs may be smaller.
Watering Needs
Garlic likes consistent moisture but not waterlogged conditions. Aim to keep the soil evenly moist like a wrung-out sponge. Overwatering can cause the cloves to rot, especially in the cool months.
During the winter, if you planted in the fall, you might not need to water much at all unless the weather is very dry. Once spring hits and growth resumes, you’ll need to water regularly, usually once or twice a week depending on your climate.
Always check the top inch of soil: if it feels dry, it’s time to water.
Fertilizing Garlic in Pots
Container plants lose nutrients faster than those in the ground, so a little fertilization helps. Start by mixing compost into your soil at planting time.
Once shoots appear:
- Feed with a balanced fertilizer (like a 10-10-10) every 3–4 weeks.
- When bulbs start to form (around late spring), switch to a fertilizer higher in potassium to boost bulb development.
Avoid over-fertilizing. Too much nitrogen can cause lush leafy growth at the expense of the bulbs.
Sunlight Requirements
Garlic needs full sun, meaning at least 6–8 hours of direct sunlight daily. Place your pots in the sunniest spot available.
If you live in a hot area, afternoon shade can actually help during the peak of summer heat, especially if the garlic is still maturing.
Rotate the pots occasionally to make sure all sides of the plants get even sun exposure.
Managing Temperature
Garlic likes cool roots and moderate air temperatures. If you’re planting in fall, your garlic will overwinter just fine in most areas.
If hard frosts are expected, you can:
- Move pots closer to the house for warmth.
- Mulch heavily with straw or shredded leaves to insulate the soil.
- Wrap pots in burlap if extreme cold hits.
In summer, avoid letting pots dry out or overheat. Watering regularly and shading roots helps.
Mulching for Better Growth
Mulching helps garlic stay cool, retains moisture, and suppresses weeds. In pots, use a thin layer of straw, shredded leaves, or even pine needles.
Don’t pile mulch too high. About 1–2 inches is enough. Make sure to pull the mulch back a bit from the stems in the spring as growth speeds up.
Common Problems and How to Fix Them
Yellowing Leaves: Often a sign of overwatering or poor drainage. Let the soil dry slightly between watering.
Small Bulbs: Can happen if garlic didn’t get enough cold exposure, was planted too late, or had too much nitrogen during growth.
Pests: Aphids might show up. A strong water spray or insecticidal soap usually handles them.
Diseases: Root rot and fungal diseases can occur if pots stay too wet. Good drainage and proper spacing help prevent this.
Stay observant. Catching issues early gives you time to fix them before they ruin your harvest.
What Are Garlic Scapes?
If you’re growing hardneck garlic, you’ll see curly green stalks emerging in late spring or early summer. These are called garlic scapes.
Garlic scapes are the flower stalks of the garlic plant. If left alone, they would eventually produce tiny bulbils (mini garlic bulbs). However, letting scapes mature can reduce the size of your garlic bulbs because the plant focuses energy on the flower instead of the bulb.
Here’s what to do:
- Cut scapes once they curl but before they straighten.
- Use clean, sharp scissors or pruners.
- Cut the stalk about 1/4 inch above the top leaf.
Bonus: Scapes are edible! They taste like mild, fresh garlic and are amazing in stir-fries, pesto, or even grilled.
Removing scapes encourages bigger bulbs. It’s a win-win.
Harvesting Garlic in Pots
Patience is key with garlic. It’s a long-growing crop, often taking 8–9 months to mature.
You’ll know it’s harvest time when:
- The bottom 3–4 leaves turn brown and dry.
- The top leaves are still green.
If you wait too long, bulbs can split, making them harder to store.
How to harvest:
- Stop watering about 1–2 weeks before harvest to let the soil dry slightly.
- Gently loosen the soil with your hands or a small fork.
- Grasp the base of the plant and pull carefully.
- Shake off excess soil but don’t wash the bulbs yet.
Be gentle. Bruising the garlic can lead to rot during storage.
Curing Your Garlic
Curing is essential for storing garlic. Freshly harvested bulbs are too moist and can mold if stored immediately.
Steps for curing:
- Bundle garlic in small groups (4–6 plants).
- Hang them in a well-ventilated, dry, shaded area.
- Alternatively, lay them out on racks or screens.
- Cure for 2–4 weeks until the skins are papery and the necks are fully dry.
Ideal conditions: temperatures around 70°F and humidity below 50%.
Once cured:
- Cut off the roots with scissors.
- Trim the stems if you like (unless you’re braiding them).
- Brush off any loose dirt. Do not peel the cloves!
Properly cured garlic will store for months.
Storing Garlic
Garlic stores best in a cool, dry, dark place. Ideal storage conditions are 60°F with low humidity.
Good storage options:
- Mesh bags
- Paper bags
- Open baskets
Avoid plastic bags—they trap moisture and encourage mold.
Softneck varieties can store for 6–9 months. Hardneck types usually last 4–6 months.
Check your garlic regularly. If you see sprouting, use those bulbs first.
Tips for Growing Big, Healthy Garlic in Pots
Want bigger bulbs and better yields? Here are some key success tips:
- Use Big Pots: More soil volume means more root space and less temperature fluctuation.
- Choose Large Cloves: Big cloves often produce big bulbs.
- Give Them a Chill: Garlic needs a cold spell. In warm climates, refrigerate cloves for 6–8 weeks before planting.
- Feed Regularly: Container garlic needs periodic feeding. Compost tea works well too.
- Don’t Rush Harvest: Waiting for the right time maximizes bulb size.
- Watch the Water: Consistent, moderate watering is vital. Wet feet or dry spells both harm growth.
- Rotate Containers: Move your pots to prevent disease buildup and avoid soil fatigue.
Troubleshooting Advanced Problems
Bulbs Are Tiny
Possible causes:
- Planted too late.
- Not enough sun.
- Soil was too compacted.
- Garlic didn’t get a cold period.
Fix by adjusting your planting time and conditions next season.
Garlic Plants Fell Over Early
If garlic plants collapse before harvest, it’s usually from:
- Root rot (overwatering).
- Severe nutrient deficiencies.
- Pests like onion maggots.
Review your watering habits. Make sure your pots drain fast enough. Inspect roots for signs of rot.
Leaves Turn Brown Too Soon
Brown leaves in early spring often signal a problem. Check for:
- Overfertilization (burns roots).
- Underwatering.
- Disease like rust fungus.
Trim affected leaves, ease up on feeding, and improve airflow around your pots.
Can You Grow Garlic Indoors Year-Round?
Short answer: sort of, but it’s tricky.
Garlic needs a cold period to form bulbs. Without a chill (vernalization), you’ll mainly get garlic greens, not full bulbs.
If you just want garlic greens:
- Plant cloves shallowly in a small pot.
- Place under a bright grow light.
- Harvest the greens like chives.
For bulb production indoors, you must simulate winter by refrigerating cloves first and using strong grow lights. Even then, bulbs may be smaller than outdoor-grown garlic.
It’s doable but takes effort. Easier to grow outside in pots unless you love a challenge.
Bonus: Fun Garlic Varieties to Try
Garlic comes in many varieties. If you want to experiment, here are a few exciting options:
- Music (Hardneck): Big cloves, rich flavor.
- Chesnok Red (Hardneck): Sweet when roasted.
- Inchelium Red (Softneck): Mild and great for braiding.
- California Early (Softneck): Easy to grow, good for beginners.
Trying different types lets you find your favorite and improves your skills.
How Many Garlic Bulbs Can You Grow in One Pot?
Depends on the pot size. Here’s a rough guide:
- 10-inch pot: 3–4 cloves
- 14-inch pot: 6–8 cloves
- 20-inch pot: 10–12 cloves
Remember to keep 4–6 inches of space between each clove. Crowding them reduces bulb size and increases disease risk.
If you have several pots, you can stagger planting times for a longer harvest window.
Growing Garlic in Pots: A Season-by-Season Guide
Understanding what your garlic needs throughout the year helps you avoid mistakes and boost your success. Here’s how to manage your garlic pot by season:
Fall: Planting and Prepping
Fall is the prime time for planting garlic. Garlic needs a period of cold to trigger bulb formation. Here’s what you do:
- Choose your cloves: Pick the biggest, healthiest cloves from your seed garlic.
- Prepare your pots: Fill with fresh, light soil mixed with compost.
- Plant before frost: Ideally, 2–4 weeks before your first hard freeze.
- Water once: Give a deep watering right after planting.
- Mulch: Add a thin layer of straw or leaves to insulate the soil.
In fall, garlic focuses on root development. You may see small green shoots before winter, but that’s normal and no problem.
Winter: Rest and Protection
Garlic is dormant during winter. It’s tough and can survive cold snaps, especially if mulched.
- Minimal watering: Only water if the soil becomes bone dry.
- Monitor mulch: If heavy rains flatten your mulch, fluff it up to protect the cloves.
- Move if needed: In extreme freezes, shift pots against a wall or into a garage temporarily.
Garlic needs this cold period to produce big, strong bulbs later.
Spring: Growth and Feeding
As days lengthen and temperatures rise, garlic wakes up.
- Remove heavy mulch: In early spring, pull back most of the mulch to let soil warm faster.
- Feed: Give a light balanced fertilizer every 3–4 weeks.
- Water consistently: Keep soil moist but not soggy.
- Watch for scapes: In hardneck varieties, scapes appear in late spring — harvest them to boost bulb size.
Spring is a critical time. Strong green growth now means bigger bulbs later.
Summer: Maturity and Harvest
Summer is harvest time.
- Reduce watering: About 2–3 weeks before harvest, let the soil dry out a bit. This improves bulb curing.
- Harvest smart: Don’t wait until all the leaves die — 4–5 green leaves mean it’s harvest time.
- Cure garlic: Hang your bulbs in a shaded, dry spot for a few weeks.
In pots, summer heat can dry out soil fast. Keep a close eye and adjust watering if needed, especially during heat waves.
DIY Garlic Growing Projects for Home Gardeners
Growing garlic in pots can be as simple or creative as you want. Here are a few easy DIY project ideas to make it fun:
1. Garlic in Wooden Crates
Old wooden crates (like wine boxes) make great shallow garlic containers. Drill drainage holes, fill with light soil, and plant cloves 4–6 inches apart. These crates look rustic and beautiful on balconies or patios.
2. Vertical Garlic Towers
Use a fabric grow tower (normally used for strawberries) to plant garlic vertically. Each pocket holds a clove. This maximizes space, looks cool, and produces a ton of garlic in a small footprint.
3. Repurposed Buckets
Five-gallon buckets are perfect for garlic. Drill holes in the bottom, fill with soil, and plant 3–4 cloves per bucket. Buckets are cheap, easy to move, and great for beginners.
4. Themed Garlic Herb Planters
Plant garlic alongside herbs like thyme, rosemary, or sage in a wide container. These herbs are garlic-friendly and will thrive with the same sunlight and watering needs.
Common Mistakes Beginners Make (And How to Avoid Them)
Growing garlic in pots isn’t hard, but beginners sometimes trip up. Here’s what to watch out for:
Mistake 1: Using Grocery Store Garlic
- Problem: It may be treated not to sprout.
- Solution: Always use certified seed garlic from a reputable supplier.
Mistake 2: Planting Cloves Too Shallow
- Problem: Cloves dry out or get pushed out by frost.
- Solution: Plant cloves 2–3 inches deep.
Mistake 3: Overwatering
- Problem: Leads to rot and fungal diseases.
- Solution: Water deeply but let the top inch dry before watering again.
Mistake 4: Poor Soil Choice
- Problem: Heavy soil stunts root growth.
- Solution: Use loose, well-draining potting mix with compost.
Mistake 5: Skipping the Cold Period
- Problem: Bulbs fail to form.
- Solution: Plant in fall, or simulate winter by refrigerating cloves if necessary.
Recognizing these pitfalls early means a better, bigger garlic harvest.
Best Companion Plants for Garlic in Pots
Garlic doesn’t just grow well alone. It also plays nicely with some other plants. Here’s who makes a good neighbor in your pots:
- Lettuce: Fast-growing and shallow-rooted, perfect for early-season interplanting.
- Strawberries: Garlic can help repel pests that love strawberries.
- Spinach: Another quick crop that fits between garlic stems.
- Herbs (thyme, rosemary, sage): Compatible watering and sunlight needs.
Avoid planting garlic with:
- Beans
- Peas
- Asparagus
These crops don’t get along well with garlic because it can stunt their growth.
Smart companion planting maximizes your space and boosts plant health.

Garlic Growing Myths — Busted
There’s a lot of misinformation about growing garlic, especially in containers. Let’s clear a few things up.
Myth 1: Garlic Needs Tons of Space
Truth: Garlic needs about 4–6 inches between cloves, but it thrives in containers if you space them properly. You don’t need a backyard — a few pots will do.
Myth 2: You Must Fertilize Constantly
Truth: Over-fertilizing does more harm than good. A light feeding every 3–4 weeks is enough, especially if you started with rich soil.
Myth 3: You Can Only Grow Garlic Outdoors
Truth: While outdoor conditions are ideal, you can grow garlic indoors if you chill the cloves first and provide strong light. It’s harder, but it’s possible.
Myth 4: You Can Plant Grocery Store Garlic
Truth: Grocery store garlic might not sprout or could carry diseases. Always plant seed garlic unless you’re experimenting.
Myth 5: Garlic Is a “Plant and Forget” Crop
Truth: Garlic is low maintenance, but it still needs consistent watering, feeding, and disease monitoring to reach its full potential.
Knowing fact from fiction sets you up for a harvest you can actually brag about.
