How to Plant Garlic in the Fall: A Comprehensive Guide to Bumper Crops
Planting garlic in the fall involves strategically timing your planting before the ground freezes, ensuring the cloves develop strong roots over the winter, which leads to robust growth and significantly larger bulbs the following summer. It’s essential to choose the right variety for your region and prepare your soil properly for optimal results.
Why Fall Planting is Key for Garlic Success
Garlic isn’t just another spring planting. While spring-planted garlic can technically grow, fall planting leverages the cooler months to allow cloves to establish strong root systems. This robust root development is crucial for maximizing bulb size and overall yield the following summer. Imagine a plant already well-rooted and ready to explode with growth when the weather warms!
Understanding Garlic Varieties
Garlic comes in two main types: hardneck and softneck.
- Hardneck: These varieties are more cold-hardy and generally perform better in regions with colder winters. They produce a flower stalk called a “scape” which should be removed to direct energy towards bulb development. Hardneck garlic also tends to have a more complex and intense flavor.
- Softneck: These are more adaptable to warmer climates and are often the type you see braided. Softneck garlic generally stores longer than hardneck varieties.
Choosing the right variety for your climate is critical. Local nurseries and agricultural extension offices can provide recommendations tailored to your specific region.
Preparing the Soil
Garlic thrives in well-drained soil that is rich in organic matter. Prepare the soil several weeks before planting to allow amendments to incorporate fully.
- Amendments: Incorporate compost, well-rotted manure, or other organic matter to improve soil fertility and drainage.
- pH: Garlic prefers a slightly acidic to neutral soil pH (around 6.0-7.0). A soil test can help determine if you need to adjust the pH.
- Drainage: Ensure the soil drains well. Raised beds or amending with coarse sand can improve drainage in heavy clay soils.
The Planting Process: Step-by-Step
Planting garlic is relatively straightforward but following these steps carefully will ensure success.
- Choose Your Planting Time: Plant garlic 4-6 weeks before the ground freezes in your area. This typically falls between late September and early November for most regions.
- Select Your Cloves: Use the largest and healthiest cloves from your seed garlic bulbs. These will produce the largest bulbs.
- Spacing: Plant cloves 6-8 inches apart within rows, with rows spaced 10-12 inches apart.
- Depth: Plant cloves 2-3 inches deep, with the pointed end facing up.
- Cover with Soil: Cover the cloves with soil and gently firm the soil surface.
- Mulch: Apply a 4-6 inch layer of mulch, such as straw, shredded leaves, or wood chips. This helps insulate the soil, retain moisture, and suppress weeds.
Fertilizing Your Garlic
Garlic is a heavy feeder. Side-dress with a balanced organic fertilizer in the spring when new growth emerges. A second feeding can be applied a few weeks later. Avoid excessive nitrogen, which can promote leafy growth at the expense of bulb development.
Pest and Disease Management
Garlic is generally pest-resistant, but some common issues include:
- Onion Thrips: Tiny insects that can damage leaves. Control with insecticidal soap or neem oil.
- Garlic Mites: Microscopic mites that can cause stunted growth. Use certified disease-free seed garlic.
- White Rot: A fungal disease that can cause bulbs to rot. Ensure good soil drainage and avoid planting garlic in areas with a history of white rot.
Harvesting and Curing
Harvest garlic when the bottom leaves begin to turn brown and die back. This is usually in mid-summer.
- Harvesting: Gently dig up the bulbs, being careful not to damage them.
- Curing: Cure garlic in a well-ventilated area for 2-3 weeks. Hang the bulbs or spread them out on screens. Once cured, the outer skins will be dry and papery.
Common Mistakes to Avoid
- Planting too late in the fall.
- Using small or unhealthy cloves.
- Planting in poorly drained soil.
- Failing to mulch.
- Over-fertilizing.
- Harvesting too early or too late.

Frequently Asked Questions (FAQs)
What is the best type of garlic to plant?
The best type of garlic to plant depends on your climate. Hardneck varieties are generally recommended for colder climates, while softneck varieties are better suited for warmer regions. Consult with your local nursery or agricultural extension office for recommendations specific to your area.
Can I plant garlic from the grocery store?
While technically possible, it’s not recommended to plant garlic from the grocery store. Grocery store garlic is often treated to prevent sprouting and may not be adapted to your local climate. It also carries the risk of introducing diseases. It’s always best to use seed garlic from a reputable source.
How deep should I plant garlic cloves?
Garlic cloves should be planted approximately 2-3 inches deep. This depth provides adequate protection from freezing temperatures and ensures good root development. Deeper planting can delay emergence, while shallower planting can make the cloves susceptible to frost heave.
How much space should I leave between garlic plants?
Leave approximately 6-8 inches between garlic plants within rows and 10-12 inches between rows. This spacing allows for adequate air circulation and room for bulb development. Denser planting can lead to smaller bulbs and increased disease risk.
Do I need to fertilize my garlic plants?
Yes, garlic is a heavy feeder and benefits from regular fertilization. Side-dress with a balanced organic fertilizer in the spring when new growth emerges. A second feeding can be applied a few weeks later. Avoid over-fertilizing with nitrogen, which can promote leafy growth at the expense of bulb development.
When should I harvest my garlic?
Harvest garlic when the bottom leaves begin to turn brown and die back. This is usually in mid-summer. Harvesting too early can result in smaller bulbs, while harvesting too late can cause the bulbs to split and deteriorate. A gentle “test dig” of a bulb or two can help determine if they are ready.
How do I cure garlic?
Curing garlic is essential for long-term storage. After harvesting, hang the bulbs or spread them out on screens in a well-ventilated area for 2-3 weeks. Once cured, the outer skins will be dry and papery, and the necks will be tight. Proper curing prevents mold and spoilage.
What is a garlic scape, and should I remove it?
A garlic scape is the flower stalk produced by hardneck garlic varieties. Removing the scape allows the plant to direct more energy towards bulb development, resulting in larger bulbs. Cut the scape off when it curls around once or twice. Scapes are also edible and can be used in cooking.
How do I store garlic after it’s cured?
Store cured garlic in a cool, dry, and well-ventilated place. Braiding softneck garlic varieties is a traditional storage method. Hardneck varieties can be stored loose in mesh bags or baskets. Avoid storing garlic in the refrigerator, as this can cause it to sprout.
My garlic plants have yellow leaves. What’s wrong?
Yellow leaves can indicate several problems, including nutrient deficiencies, pests, or diseases. Check the soil pH, fertilize appropriately, and inspect the plants for signs of pests or diseases. Early detection and treatment are crucial for preventing further damage.
Can I plant garlic in containers?
Yes, garlic can be grown in containers, but it requires a large container (at least 12 inches in diameter) and well-drained potting mix. Container-grown garlic may not produce bulbs as large as those grown in the ground, but it can still be a rewarding experience. Ensure proper drainage to avoid root rot.
How do I know if my soil is draining well enough for garlic?
A simple drainage test can help determine if your soil is draining well enough. Dig a hole about 12 inches deep and fill it with water. If the water drains away within a few hours, the soil is likely draining well. If the water remains for longer than 24 hours, the soil may need to be amended to improve drainage. Poorly draining soil can lead to bulb rot.
