Garlic, with its pungent aroma and robust flavor, has been a kitchen staple for centuries. Cultivating this versatile herb in your own garden not only ensures a fresh and abundant supply but also offers a rewarding gardening experience.

As a bonus, garlic repels a variety of pests, so it is a good crop to place in the garden as a companion plant. In this guide, we'll take you through the step-by-step process of growing garlic successfully, from selecting the right varieties to harvesting and storing your flavorful bulbs.

Choosing the Right Garlic Varieties

Before you get your hands dirty, it's crucial to choose the right garlic varieties for your climate and preferences. There are two main types of garlic: hardneck and softneck.

  • Hardneck Garlic: Ideal for colder climates, hardneck varieties produce a central stalk or scape. Common types include Rocambole, Porcelain, and Purple Stripe.
  • Softneck Garlic: Well-suited for milder climates, softneck varieties lack a central stalk and have a softer, braided stem. Artichoke and Silverskin are popular softneck varieties.

Planting Time and Location

Garlic is typically planted in the fall, allowing it to establish roots before winter. Select a sunny location with well-draining soil. Prepare the soil by adding organic matter and ensuring a slightly acidic to neutral pH.

Planting Garlic Bulbs

  1. Separate Bulbs into Cloves: Before planting, break apart the garlic bulb into individual cloves. Choose the largest, healthiest cloves for planting.
  2. Planting Depth and Spacing: Plant each clove about 2 inches deep with the pointed end facing up. Space them 4-6 inches apart, leaving 12-18 inches between rows.
  3. Mulching: Cover the planted cloves with a layer of straw or mulch to insulate them during winter and suppress weeds.

Caring for Your Garlic

  • Watering: Garlic prefers consistent moisture, especially during its early growth stages. Water regularly but avoid waterlogged conditions.
  • Fertilizing: Apply a balanced fertilizer in the spring, and side-dress with nitrogen when the plants start growing vigorously.
  • Scaping: If you're growing hardneck garlic, remove the scapes (flower stalks) when they appear. This encourages bulb development and produces a tasty bonus harvest.


Knowing when to harvest garlic is crucial for optimal flavor and storage. Harvest when the lower leaves turn brown, typically in late spring or early summer. Carefully dig up the bulbs, keeping the foliage intact. Allow the bulbs to cure in a warm, dry place for 2-3 weeks.

Storing Your Garlic Harvest

After curing, trim the roots and cut off the tops. Store garlic bulbs in a cool, dark, and well-ventilated place. Braiding softneck varieties is a traditional and space-efficient storage method.

Troubleshooting Common Issues

  • Pests: Keep an eye out for pests like aphids and onion maggots. Neem oil or insecticidal soap can help control infestations.
  • Diseases: Garlic is susceptible to fungal diseases. Practice crop rotation and avoid planting in waterlogged soil to minimize disease risk.
  • Soil Conditions: Garlic prefers well-draining soil. If the soil is too compact or waterlogged, it can lead to issues such as root rot. Ensure proper drainage and consider adding organic matter to improve soil structure.

  • Overcrowding: Planting cloves too close together can result in overcrowded conditions, limiting bulb development and airflow. Proper spacing is essential to prevent diseases and promote healthy growth.

  • Inadequate Sunlight: Garlic thrives in full sunlight. If your garden location doesn't receive at least six hours of direct sunlight, the plants may become leggy, and bulb development may be compromised. Consider choosing a sunnier spot for planting.

  • Inconsistent Watering: Fluctuating soil moisture levels can cause irregular bulb development and affect flavor. Be consistent with your watering schedule, aiming for about 1 inch of water per week, either through rainfall or irrigation.

  • Late Harvesting: Harvesting garlic too late can result in over-mature bulbs that are difficult to peel and have a reduced shelf life. Monitor the foliage, and once about half of the leaves have turned brown, it's time to harvest for optimal flavor and storage.

  • Storage Conditions: Improper storage can lead to premature sprouting or mold. Ensure that your storage area maintains cool temperatures (around 60°F or 15°C), low humidity, and good ventilation. Avoid storing garlic in the refrigerator, as it can cause sprouting.

Growing garlic successfully is a gratifying journey that rewards your efforts with a bountiful harvest of flavorful bulbs. With the right varieties, proper planting techniques, and attentive care, you'll soon be enjoying the rich taste and aroma of homegrown garlic in your culinary creations. Happy gardening!
