Garlic (Allium sativum) is one of the easiest crops to grow in a garden. It requires minimal space, is low-maintenance, and rewards you with a flavorful harvest that can last for months. Whether you’re a beginner or an experienced gardener, growing garlic can be a fulfilling experience. With a few key steps, you can plant, nurture, and harvest your own garlic bulbs right from your garden.
This guide will take you through the process of growing garlic step by step, from planting the cloves to harvesting the mature bulbs.
Step 1: Choose the Right Garlic Variety
There are mainly two kinds of garlic: hardneck and softneck. Each variety has unique characteristics, and choosing the right one for your climate and needs is the first step toward success.Hardneck Garlic:
• Best for cold climates: Hardneck garlic thrives in regions with cold winters. It requires a period of cold dormancy (vernalization) to develop properly.
• Produces garlic scapes: These are edible flowering stalks that grow from the plant and can be harvested for additional use.
• Fewer, larger cloves: Hardneck garlic typically produces fewer cloves per bulb, but the cloves are larger and easier to peel.
• Popular varieties: ‘Rocambole,’ ‘Purple Stripe,’ and ‘Porcelain.’
Softneck Garlic:
• Best for warmer climates: Softneck garlic is more tolerant of mild winters and doesn’t require cold dormancy.
• Longer shelf life: Softneck varieties store longer, making them ideal for extended use.
• More cloves per bulb: These bulbs produce more, smaller cloves, which can be a bit more difficult to peel but offer more yield.
• Popular varieties: ‘Silverskin’ and ‘Artichoke.’
Choose a variety based on your climate and how you plan to use the garlic.
Step 2: Prepare the Garden Bed
Garlic needs loose, well-drained soil to grow properly. Preparing your garden bed ensures that the garlic bulbs will develop well and avoid issues like waterlogging or rot.
Soil Requirements:
• Well-draining, loamy soil: Garlic prefers slightly sandy or loamy soil that drains well. Heavy clay soils can be improved by adding organic matter like compost or aged manure.
• pH level: Garlic grows best in soil with a pH of 6.0 to 7.0. Test your soil and amend it if necessary with lime (to raise pH) or sulfur (to lower pH).
• Amend the soil: Before planting, enrich the soil with compost, well-rotted manure, or a balanced organic fertilizer. Garlic is a heavy feeder, so nutrient-rich soil is key to large, healthy bulbs.
Bed Preparation:
• Location: Choose a sunny spot that gets at least 6-8 hours of sunlight daily. Garlic needs a lot of sunlight to thrive.
• Raised beds (optional): If your garden soil doesn’t drain well, consider planting garlic in raised beds to improve drainage.
Step 3: Break Apart the Garlic Bulbs
Garlic is grown by planting individual cloves rather than seeds. To get started, you’ll need to break apart your garlic bulbs into individual cloves.
How to Separate Garlic Cloves:
1. Select healthy bulbs: Choose large, firm bulbs that are free from blemishes, mold, or disease.
2. Gently separate the cloves: A few days before planting, break the garlic bulb apart into individual cloves. Leave the papery skin on each clove intact to protect it during planting.
3. Use the largest cloves: Save the smaller cloves for cooking, and plant only the largest cloves, as these will yield the biggest and healthiest bulbs.
Step 4: Plant the Garlic Cloves
Garlic is usually planted in the fall, a few weeks before the first frost, to allow it to establish roots before winter. This timing varies depending on your climate, but generally, plant garlic 6-8 weeks before the ground freezes.
How to Plant Garlic:
1. Spacing and depth: Plant each clove pointed side up, about 2-3 inches deep in the soil. Space cloves 6 inches apart, and leave about 12 inches between rows to allow for growth and airflow.
2. Mulch after planting: After planting the cloves, cover the bed with 3-4 inches of mulch (straw, leaves, or grass clippings). Mulching helps to control soil temperature, retain moisture, and suppress weeds.
3. Mark the rows: Use markers to label the variety and the date planted. This will help you keep track of the garlic’s growth and harvest time.
Step 5: Watering and Fertilizing
Garlic requires consistent moisture but doesn’t like soggy soil. Proper watering and fertilizing will promote healthy growth.
Watering:
• Water regularly: After planting, water the garlic bed thoroughly. Garlic needs about 1 inch of water per week, especially during its active growth phase in the spring.
• Reduce watering in late spring: Once the tops start to yellow and die back in late spring or early summer, reduce watering. Overwatering at this stage can lead to rotting.
Fertilizing:
• Early growth: In the spring, when green shoots emerge, fertilize the garlic bed with a high-nitrogen fertilizer, such as fish emulsion or blood meal, to promote healthy leaf growth.
• Mid-season feeding: Side-dress with a balanced fertilizer in mid-spring when the garlic begins to form bulbs. This provides the necessary nutrients for bulb development.
Step 6: Managing Pests and Diseases
Garlic is relatively resistant to most pests and diseases due to its natural sulfur compounds, which act as repellents. However, you still need to watch for certain issues.
Common Pests:
1. Onion Thrips: These small, sucking insects can damage garlic leaves. Try to use insecticidal soap or neem oil to prevent infestations.
2. Nematodes: These microscopic worms can damage garlic bulbs. Rotate crops yearly and avoid planting garlic in the same spot for consecutive seasons to prevent nematode build-up.
3. Aphids: Occasionally, aphids may feed on garlic leaves. Utilize a strong water current or insecticidal soap to get rid of them.
Common Diseases:
1. White Rot: This fungal disease causes yellowing and wilting of leaves, followed by bulb rot. Prevent it by practicing crop rotation and ensuring good soil drainage.
2. Rust: Rust appears as orange spots on garlic leaves. Removing affected leaves and applying organic fungicides can help control the spread.
Step 7: Harvesting Garlic
Garlic is ready to harvest when the lower leaves turn yellow and begin to dry, but the upper leaves are still green. This typically occurs in mid to late summer, depending on the variety and climate.
How to Harvest Garlic:
1. Stop watering: About two weeks before harvesting, stop watering the garlic to allow the bulbs to dry in the soil.
2. Loosen the soil: Use a garden fork to gently loosen the soil around the garlic bulbs. Avoid pulling them out by the leaves, as this can damage the bulbs.
3. Lift the bulbs: Carefully lift the bulbs out of the ground. Brush off excess soil, but do not wash the bulbs as they need to dry before storage.
Step 8: Curing and Storing Garlic
Curing garlic is essential for long-term storage. Well-preserved garlic has a shelf life of several months.
How to Cure Garlic:
1. Dry the bulbs: Lay the garlic bulbs in a single layer in a well-ventilated, shady area. You can also dry them by hanging them in groups. Leave the garlic to cure for 2-3 weeks.
2. Trim and clean: Once the garlic has cured, trim the roots and cut the stems, leaving about an inch above the bulb. Brush off any remaining dirt, but avoid removing too many layers of skin.
3. Store in a cool, dry place: Store the cured garlic bulbs in a cool, dry, and well-ventilated space. Softneck garlic varieties can be braided for easy storage.
Storing Conditions:
• Garlic stores best at temperatures between 50°F and 60°F with low humidity.
• Do not store garlic in the refrigerator, as this can trigger sprouting.
Step 9: Save Garlic for Replanting
After a successful harvest, consider saving some of your largest and healthiest garlic bulbs for replanting next season.
Saving Garlic for Planting:
• Choose the largest and best-formed bulbs from your harvest.
• Store them in a cool, arid location until planting time arrives in the fall.
Conclusion
Growing garlic in your garden is a simple and rewarding experience. By choosing the right variety, preparing the soil properly, and following a consistent care routine, you can enjoy a bountiful harvest of garlic with minimal effort. With the right steps, you’ll have a steady supply of flavorful garlic for cooking, medicinal use, or even replanting year after year. Happy gardening!
