Garlic is one of the most rewarding crops you can grow at home. It is easy to plant, requires little maintenance, and brings you fresh, flavorful bulbs that taste far better than store-bought garlic. The best part? You don’t need a backyard garden. You can grow garlic in pots right on your balcony, patio, or even a sunny windowsill.
Container gardening makes garlic accessible for everyone, whether you live in an apartment or simply want to maximize space in a small yard. In this guide, you’ll learn step-by-step how to grow garlic in pots, from choosing the right container to harvesting and storing your bulbs. Along the way, we’ll highlight proven gardening tips, science-backed insights, and practical tricks to ensure success.
Short answer: Growing garlic in pots is simple and rewarding—you just need a container at least 8–10 inches deep with good drainage, quality potting soil, and garlic cloves planted about 2 inches deep and 4 inches apart. Keep the pot in a sunny spot, water regularly but avoid waterlogging, and add a little compost or fertilizer as the shoots grow. With patience, you’ll see green shoots within weeks, and after several months the bulbs will be ready to harvest.
Why Grow Garlic in Pots?
Growing garlic in pots offers several unique advantages:
- Space-saving: Ideal for apartments, balconies, or small patios.
- Mobility: Pots can be moved to maximize sun exposure.
- Control: You manage the soil quality, drainage, and watering schedule.
- Pest reduction: Growing in containers helps reduce soil-borne pests and diseases.

Best Varieties of Garlic for Pots
Garlic comes in two main types:
- Hardneck garlic: Produces a flower stalk (scape) and does well in colder climates. It offers large cloves with bold flavor.
- Softneck garlic: More common in supermarkets, stores longer, and suits warmer climates.
Both types can thrive in pots, but hardneck garlic is often preferred for container gardening because it produces fewer but larger cloves. According to research on sustainable food production, choosing the right variety improves yield and quality (source).
Choosing the Right Container
The pot you select has a direct impact on your garlic harvest. Garlic roots grow deep, so shallow containers won’t work.
Container requirements:
- Depth: At least 12 inches deep.
- Width: Wide enough to allow cloves to be spaced 4–6 inches apart.
- Drainage: Must have drainage holes to prevent waterlogging.
For balcony or patio gardening, large terracotta or fabric grow bags are excellent choices. They retain moisture while allowing good airflow to the roots. The Spruce offers practical tips on growing garlic in containers that align with these best practices.
Preparing the Soil
Garlic grows best in well-draining, nutrient-rich soil. Avoid heavy clay or compacted soil, as it holds too much water and causes bulb rot.
Soil mix recipe for pots:
- 50% high-quality potting soil
- 25% compost for nutrients
- 25% sand or perlite for drainage
For an extra boost, mix in a slow-release organic fertilizer high in potassium and phosphorus. According to the Penn State Extension garlic production guide, proper soil preparation is one of the most important steps for a healthy crop.
Selecting Garlic Cloves for Planting
Always start with high-quality seed garlic rather than supermarket bulbs, which are often treated with growth inhibitors.
Tips for selecting cloves:
- Choose firm, plump cloves without blemishes.
- Avoid cloves that are shriveled, soft, or moldy.
- Larger cloves produce larger bulbs.

How to Plant Garlic in Pots
Once your pot and soil are ready, follow these steps:
- Break apart the garlic bulb into individual cloves. Do not remove the papery skin.
- Plant each clove pointed end up, 2–3 inches deep.
- Space cloves 4–6 inches apart.
- Cover with soil and lightly firm the surface.
- Water thoroughly after planting.
For year-round learning, you can also experiment with growing from scraps in pots, which uses leftover kitchen garlic to start new growth.
Watering and Light Requirements
Garlic loves sunlight and consistent moisture.
- Sunlight: Place your pot in a location with at least 6–8 hours of direct sunlight daily.
- Watering: Keep soil evenly moist but not waterlogged. Overwatering leads to bulb rot, while underwatering causes stunted growth.
Research published in Acta Horticulturae highlights that proper irrigation management directly influences garlic bulb development and quality (source).
Fertilizing Garlic in Pots
Garlic is a heavy feeder, especially when grown in containers where nutrients leach out quickly.
Fertilizer schedule:
- Apply a balanced organic fertilizer every 3–4 weeks.
- During the leafy growth stage, nitrogen-rich fertilizer helps develop strong leaves.
- Switch to potassium and phosphorus-rich fertilizer as bulbs begin forming.
A guide from the University of Nebraska Extension emphasizes the importance of balanced nutrition to achieve larger, healthier bulbs.
Managing Garlic Pests and Diseases in Containers
Container-grown garlic has fewer problems than garden-planted garlic, but it’s not immune.
Common issues:
- White rot
- Rust fungus
- Onion thrips
Prevention tips:
- Always use sterile soil and clean containers.
- Rotate crops in pots to avoid repeated soil use.
- Remove diseased leaves promptly.
Growing garlic in pots reduces the risk of soil-borne pathogens, a major benefit for urban gardeners (source).
Caring for Garlic Through the Seasons
Garlic is usually planted in the fall and harvested the following summer, but in pots, you have more flexibility.
Seasonal care:
- Fall: Plant cloves before the first frost for strong root growth.
- Winter: Protect pots with mulch or move them to a sheltered spot.
- Spring: Resume fertilizing as leafy growth increases.
- Summer: Water consistently until leaves begin to yellow, then reduce watering to allow bulbs to cure in the soil.
Harvesting Garlic from Pots
Garlic is ready to harvest when the lower leaves turn yellow while upper leaves remain green. Typically, this occurs 8–10 months after planting.
Steps to harvest:
- Stop watering 1–2 weeks before harvest.
- Loosen the soil gently and pull bulbs out by the base of the stem.
- Avoid bruising bulbs during harvest.
A step-by-step container growing guide from Groeat provides a practical harvest timeline for pot-grown garlic.
Curing and Storing Garlic
Freshly harvested garlic needs curing before storage.
- Lay bulbs out in a shaded, dry, well-ventilated space for 2–3 weeks.
- Once dry, trim roots and cut stems if desired.
- Store in a cool, dark place in mesh bags or baskets.

Companion Planting in Pots
Garlic pairs well with certain herbs and vegetables, even in containers. Basil, mint, and spinach thrive alongside garlic and may even help repel pests. If you’re exploring more ways to use garlic in your kitchen, check out how to cut garlic for cooking tips.
