How to Plant Garlic Cloves in a Pot?
Planting garlic cloves in a pot is a straightforward process involving selecting suitable cloves, preparing a well-draining potting mix, planting them at the correct depth, and providing adequate sunlight and water. This method allows you to enjoy fresh garlic even with limited garden space, and produces delicious, home-grown garlic in a relatively short time!
Why Grow Garlic in a Pot?
Growing garlic in pots offers several advantages, particularly for urban dwellers or those with limited outdoor space.
- Space Efficiency: Pots allow you to grow garlic on balconies, patios, or even indoors near a sunny window.
- Controlled Environment: You can easily control the soil quality, moisture levels, and sunlight exposure, leading to healthier and more productive plants.
- Mobility: Pots can be moved to optimize sunlight exposure or protect plants from harsh weather.
- Pest and Disease Control: Potted garlic is less susceptible to soil-borne pests and diseases compared to in-ground planting.
Choosing the Right Garlic and Pot
Selecting the right garlic variety and pot is crucial for success.
Garlic Variety: Hardneck varieties, which produce scapes (flower stalks), are generally more suitable for colder climates. Softneck varieties, which are typically what you see in the grocery store, are better for warmer climates and are easier to braid. However, either type can be grown in a pot.
- Hardneck Varieties Examples: ‘German Extra Hardy’, ‘Spanish Roja’, ‘Chesnok Red’
- Softneck Varieties Examples: ‘California Early’, ‘Silverskin’, ‘Artichoke’
Pot Size: Choose a pot that is at least 8 inches deep and 6 inches in diameter per clove. A larger pot is preferable, especially if you plan to plant multiple cloves. A good rule of thumb is a minimum of 12 inches deep and 12 inches in diameter for multiple cloves.
Material: Terracotta or plastic pots are both suitable. Terracotta pots offer better drainage, while plastic pots retain moisture better. Ensure the pot has adequate drainage holes to prevent waterlogging.
Preparing the Potting Mix
The right potting mix is essential for healthy garlic growth. Garlic needs well-draining soil to thrive.
Ingredients: Combine equal parts of the following:
- Potting Soil: Provides essential nutrients and structure.
- Compost: Adds organic matter and improves soil fertility.
- Perlite or Vermiculite: Enhances drainage and aeration.
pH Level: Aim for a soil pH of 6.0 to 7.0. You can test the soil pH using a home testing kit or by sending a sample to a local agricultural extension office.
Planting the Garlic Cloves
Follow these steps for planting your garlic cloves:
Select healthy cloves: Choose large, firm cloves from a healthy bulb. Avoid using cloves from grocery store garlic, as they may be treated to prevent sprouting or may not be suitable for your local climate.
Prepare the cloves: Separate the cloves from the bulb just before planting. Leave the papery skin intact.
Planting depth: Plant the cloves pointed end up, about 2 inches deep and 4 inches apart.
Cover with soil: Gently cover the cloves with the prepared potting mix.
Water thoroughly: Water the pot well after planting, ensuring the soil is evenly moist but not waterlogged.
Caring for Potted Garlic
Proper care is crucial for successful garlic growth.
Sunlight: Garlic needs at least 6 hours of direct sunlight per day. Place the pot in a sunny location, such as a south-facing balcony or patio.
Watering: Water regularly, especially during dry periods. Allow the top inch of soil to dry out between waterings. Avoid overwatering, which can lead to rot.
Fertilizing: Fertilize every 2-3 weeks with a balanced liquid fertilizer (e.g., 10-10-10) diluted to half strength. Stop fertilizing about a month before harvest.
Mulching: Add a layer of mulch, such as straw or wood chips, to help retain moisture and suppress weeds.
Scape Removal (Hardneck Varieties): If you are growing a hardneck variety, remove the scapes when they start to curl. Removing the scapes encourages the bulb to grow larger. Scapes are also edible and can be used in cooking.
Harvesting and Curing
Knowing when and how to harvest and cure your garlic is key.
Harvest Time: Garlic is typically ready to harvest in late spring or early summer when the lower leaves start to turn yellow and brown.
Harvesting: Gently loosen the soil around the bulb and carefully lift it out of the pot. Avoid pulling on the stalk, which can damage the bulb.
Curing: Cure the harvested garlic by hanging it in a dry, well-ventilated place for 2-3 weeks. This process allows the bulbs to dry out and develop their full flavor. After curing, trim the roots and stalks, leaving about an inch of stalk above the bulb. Store the cured garlic in a cool, dry place.
Common Mistakes
Avoid these common pitfalls when growing garlic in pots:
- Using supermarket garlic: As mentioned, these may not sprout or grow well.
- Planting too shallow or too deep: Plant at the recommended depth of 2 inches.
- Overwatering: Ensure proper drainage and avoid waterlogging.
- Insufficient sunlight: Provide at least 6 hours of direct sunlight per day.
- Neglecting fertilization: Fertilize regularly with a balanced fertilizer.

Frequently Asked Questions (FAQs)
Can I plant garlic in the spring instead of the fall?
Yes, you can plant garlic in the spring, but you likely won’t get the same size bulbs as you would from fall planting. Garlic needs a period of cold dormancy (vernalization) to develop properly. If planting in the spring, choose a variety known to tolerate warmer temperatures and consider refrigerating the cloves for a few weeks before planting to simulate cold stratification. Expect smaller bulbs and potentially less robust flavor.
How often should I water my potted garlic?
Watering frequency depends on several factors, including climate, pot size, and soil type. As a general rule, water when the top inch of soil feels dry to the touch. Avoid overwatering, which can lead to bulb rot. During hot, dry periods, you may need to water more frequently.
What type of fertilizer is best for potted garlic?
A balanced liquid fertilizer, such as a 10-10-10 or 20-20-20, diluted to half strength, is suitable for potted garlic. Fertilize every 2-3 weeks during the growing season. You can also use organic fertilizers, such as compost tea or fish emulsion. Avoid fertilizers that are high in nitrogen, as they can promote leaf growth at the expense of bulb development.
How do I protect my potted garlic from frost?
If you live in an area with harsh winters, you can protect your potted garlic from frost by moving it to a sheltered location, such as a garage or shed. You can also cover the pot with burlap or a blanket. Alternatively, bury the pot in the ground for insulation. Once the threat of frost has passed, you can move the pot back to its sunny location.
Can I grow garlic indoors?
Yes, you can grow garlic indoors, but it requires a sunny location and adequate light. Place the pot near a south-facing window or use grow lights to provide sufficient light. Indoor-grown garlic may not produce as large bulbs as outdoor-grown garlic, but you can still harvest and use the green shoots (garlic greens) in cooking.
What are garlic scapes, and what do I do with them?
Garlic scapes are the flower stalks that grow from hardneck garlic varieties. They are typically removed to encourage the bulb to grow larger. Scapes are edible and have a mild garlic flavor. They can be used in stir-fries, pesto, or grilled.
Why are my garlic leaves turning yellow?
Yellowing garlic leaves can be caused by several factors, including overwatering, nutrient deficiency, disease, or pests. Check the soil moisture and adjust watering accordingly. Fertilize with a balanced fertilizer. Inspect the leaves for signs of disease or pests and treat as needed. Natural yellowing occurs as harvest time approaches.
What pests or diseases commonly affect potted garlic?
Common pests that can affect potted garlic include aphids, thrips, and spider mites. Diseases include bulb rot, white rot, and downy mildew. Regularly inspect your plants for signs of pests or diseases and treat them promptly with appropriate insecticides or fungicides. Proper watering and good air circulation can help prevent disease.
How long does it take to grow garlic in a pot?
Garlic typically takes 6-9 months to mature, depending on the variety and climate. Fall-planted garlic is usually ready to harvest in late spring or early summer. Spring-planted garlic will take longer and may not produce as large bulbs.
Can I reuse the potting mix after harvesting garlic?
It’s generally recommended to use fresh potting mix each year to avoid the buildup of pests and diseases. However, if you want to reuse the potting mix, you can amend it with compost and fertilizer to replenish nutrients. Sterilize the soil by baking it in the oven at 180°F (82°C) for 30 minutes to kill any pathogens.
How do I store garlic after harvesting?
After curing the garlic for 2-3 weeks, trim the roots and stalks, leaving about an inch of stalk above the bulb. Store the cured garlic in a cool, dry, well-ventilated place. A temperature of 60-70°F (15-21°C) is ideal. Avoid storing garlic in the refrigerator, as this can cause it to sprout or become moldy.
Can I plant garlic in the same pot as other herbs or vegetables?
Garlic can be planted alongside certain companion plants, such as chamomile, dill, and marigolds, which can help deter pests. Avoid planting garlic near beans or peas, as they can inhibit each other’s growth. Ensure that both plants have adequate space and resources. Consider the watering needs of each plant to avoid overwatering or underwatering.
