Garlic is an essential kitchen staple, adding bold flavor to countless dishes—and the best part is, it’s incredibly easy to grow, even in small spaces. You don’t need a large garden to enjoy a bountiful garlic harvest. With just a pot, some good soil, and a bit of patience, you can grow fresh garlic right on your balcony, patio, or windowsill.
In this guide, you’ll learn everything you need to know about growing garlic in containers—from selecting the right garlic cloves to harvesting your own homegrown bulbs.
Why Grow Garlic in Containers?
Growing garlic in containers is perfect for gardeners with limited space or poor garden soil. It allows you to control the growing environment, helps manage pests, and makes it easy to move the plants for optimal sunlight exposure. It’s also surprisingly low-maintenance and rewarding.
Best Garlic Type for Containers
There are two main types of garlic:
-
- Softneck (Allium sativum): Better for milder climates, stores longer, and often produces more cloves per bulb. Great for container growing.
- Hardneck (Allium ophioscorodon): Best for colder climates, with fewer but larger cloves and a stronger flavor.
Choose garlic bulbs from a reputable seed supplier or garden center. Avoid grocery store garlic, which is often treated to prevent sprouting.
When to Plant Garlic
Garlic is typically planted in the fall (4–6 weeks before the first frost) to allow roots to develop before winter dormancy. However, in warmer climates or indoor setups, you can plant garlic in late winter or early spring and still get a decent harvest.
What You’ll Need
-
- Garlic bulbs (softneck or hardneck)
-
- Container or grow bag (at least 10–12 inches deep)
- Quality potting mix with compost
- Organic fertilizer (optional)
- Watering can
- Sunny location (6–8 hours of sunlight daily)
Step-by-Step Guide to Growing Garlic in Containers
1. Prepare the Container
Choose a container with good drainage holes. A depth of at least 10 inches is ideal to support proper bulb development. You can use terracotta pots, grow bags, or plastic containers, as long as they drain well.
Fill the container with a mix of well-draining potting soil and compost. Garlic prefers loose, fertile soil rich in organic matter.
2. Prepare the Garlic Cloves
Separate the garlic bulb into individual cloves, keeping the papery skin intact. Select the largest, healthiest cloves—these will produce the best bulbs. Discard any that are soft, damaged, or moldy.
3. Plant the Cloves
Plant each clove with the pointed end facing up and the flat end (root side) down. Push each clove about 2–3 inches deep into the soil and space them 4–6 inches apart. If you’re planting in rows within a container, leave about 6 inches between rows.
Gently firm the soil around each clove and water lightly.
Garlic Growing Care
Sunlight
Garlic needs full sun—at least 6 to 8 hours a day. Place your container in a bright, sunny spot. If growing indoors, consider using a grow light during winter months.
Watering
Keep the soil evenly moist, especially during the early growing stages. Don’t let the soil become soggy, as garlic dislikes sitting in water. Reduce watering in the last few weeks before harvest to help the bulbs mature and dry out.
Fertilizing
If your soil mix is rich in compost, additional feeding may not be necessary. However, a light feeding with an all-purpose organic fertilizer or liquid seaweed every few weeks during the growing season can support healthy development.
Growth Stages and Scapes
If growing hardneck garlic, you may notice long, curly stalks called scapes growing in late spring or early summer. These are edible and should be cut off to redirect the plant’s energy into developing the bulb.
Scapes have a mild garlic flavor and are delicious in stir-fries, pesto, and soups.
Harvesting Garlic
Garlic is usually ready for harvest 7–9 months after planting. In general:
- Fall-planted garlic is ready by late spring or early summer.
- Spring-planted garlic will be ready by late summer.
You’ll know it’s time to harvest when the lower leaves start to turn yellow and dry while the upper leaves remain green. Carefully loosen the soil and gently lift the bulbs out. Don’t pull the stalks—they can snap.
Curing and Storing
After harvesting, brush off excess soil (don’t wash) and allow the garlic to cure in a dry, well-ventilated, shaded area for 2–3 weeks. Hang them in bunches or spread them out on racks. Once the outer layers are dry and papery, trim the roots and stems.
Store cured garlic in a cool, dry place. Properly cured garlic can last several months.
Final Tips
-
- Rotate containers or change soil if replanting garlic in the same pot each year to avoid disease buildup.
- Keep weeds and competing plants out of the container.
- Save a few of your largest cloves for replanting next season.
Conclusion
Growing garlic in containers is an easy and satisfying way to bring fresh, flavorful cloves to your kitchen. With a bit of preparation and care, you can enjoy a hands-off, space-saving harvest whether you garden on a balcony, patio, or windowsill. Start with quality cloves, give them light and water, and let time work its magic—soon you’ll be pulling up your very own garlic bulbs, grown entirely at home.
