Growing Garlic in Containers: A Step-By-Step Guide

Growing garlic in containers offers so many benefits, particularly for those with limited garden space or challenging soil conditions.

Containers allow better control over soil quality, ensuring optimal drainage and nutrient levels, which can lead to healthier garlic bulbs. This method also reduces the risk of pests and diseases, as the isolated environment is easier to manage.

Additionally, container gardening makes garlic more accessible, especially for urban gardeners, and allows for easy mobility, so you can place the containers in the best sun-exposed spots. It’s a convenient way to enjoy fresh garlic with less space and maintenance.

How to Grow Garlic in Containers

Garlic is one of the easiest crops to grow, and if you don’t have a lot of space, growing garlic in containers is a great option. Container gardening is perfect for small spaces like balconies, patios, or even windowsills, and garlic thrives just as well in containers as it does in traditional garden beds.

This guide will walk you through everything you need to know about growing garlic in containers successfully.

Why Grow Garlic in Containers?

Growing garlic in containers offers several benefits:

• Space efficiency: Even if you lack garden space, you can still grow garlic.
• Control over soil quality: You can customize the soil mixture to ensure optimal growing conditions.
• Mobility: Containers can be moved to take advantage of sunlight and protect plants from harsh weather.
• Pest management: Growing in containers can reduce the likelihood of pests that typically affect garden-grown garlic.

Choosing the Right Garlic Variety

Garlic comes in two main types: hardneck and softneck.

• Hardneck garlic is more suited to cooler climates and produces larger cloves with more complex flavors. It also produces a central stalk called a scape, which is edible.
• Softneck garlic grows better in milder climates and typically stores for longer periods after harvesting.

Choose the variety based on your climate and storage needs. If you’re new to garlic growing, softneck varieties are a good starting point.

Selecting the Container

Garlic has deep roots, so you’ll need a container that is at least 12 inches deep and 12-18 inches wide. This depth ensures that the roots have enough room to grow, and the width allows you to plant multiple cloves.

Ensure that the container has good drainage holes to prevent waterlogged soil, which can rot the garlic.

Best Soil for Garlic

Garlic grows best in loose, well-draining soil. Use a high-quality potting mix and amend it with organic matter like compost or well-rotted manure.

Garlic prefers soil with a pH between 6.0 and 7.0, so it’s a good idea to test your soil and adjust it with lime if necessary.

You can create a suitable potting mix by combining:

• 2 parts potting soil
• 1 part compost or well-rotted manure
• 1 part perlite or sand (for better drainage)

Planting Garlic in Containers

1. Break apart the bulb: Separate the garlic bulb into individual cloves, but leave the papery husk on each clove. Choose the largest and healthiest cloves for planting, as these will produce the best bulbs.
2. Plant the cloves: Make holes about 2-3 inches deep in the soil, spacing each clove about 4-6 inches apart. Ensure that the pointed end is facing up and the flat end is down. Cover the cloves with soil, leaving about 1 inch of space at the top of the container.
3. Water the garlic: After planting, water the container thoroughly until the soil is evenly moist. Garlic does not like to sit in water, so make sure the excess water drains out of the bottom.
4. Mulch: To help retain moisture and keep the soil temperature consistent, add a layer of organic mulch such as straw, shredded leaves, or grass clippings on top of the soil.

Watering and Care

Garlic needs consistent moisture but does not like to be waterlogged. Water the container when the top inch of soil feels dry. During the growing season, aim to keep the soil evenly moist but never soggy.

Place the container in a spot that receives full sunlight—garlic needs at least 6-8 hours of sunlight a day. If you’re growing indoors, ensure the container is placed near a sunny window, or use grow lights.

Fertilizing Garlic

Garlic is a heavy feeder and will benefit from regular feeding throughout its growing cycle. Use a balanced organic fertilizer or compost tea every 4-6 weeks to provide essential nutrients.

Nitrogen-rich fertilizers are particularly beneficial during the early stages of growth to promote healthy green leaves.

Managing Pests and Diseases

Growing garlic in containers reduces the risk of soil-borne pests and diseases, but it’s still important to keep an eye on your plants. The most common issues are:

• Aphids: These tiny insects can be managed with neem oil or insecticidal soap.
• Fungal diseases: Ensure good air circulation around the plants and avoid overwatering to prevent fungal infections.

Harvesting Garlic

Garlic is typically ready for harvest in 8-9 months, depending on the variety. You’ll know it’s time to harvest when the leaves turn yellow and begin to dry out. Here’s how to harvest garlic:

1. Stop watering: About 2-3 weeks before harvesting, stop watering the garlic to allow the bulbs to dry out.
2. Loosen the soil: Use a small garden fork to gently loosen the soil around the garlic bulb, taking care not to damage it.
3. Pull the bulbs: Carefully pull the garlic out of the soil by its leaves.
4. Cure the garlic: Lay the harvested garlic in a well-ventilated, dry area to cure for 2-3 weeks. This allows the skins to harden and helps the garlic store better.

Growing Garlic Greens

If you’re looking for a faster crop, you can also grow garlic greens in containers. Plant the cloves more densely, about 2 inches apart, and harvest the green shoots when they reach about 8 inches tall.

Garlic greens are a delicious addition to salads, stir-fries, and soups.
