How to Plant Garlic in the Fall: Planting, Care & Harvest Guide

There’s something deeply satisfying about breaking open a head of homegrown garlic—the pungent aroma that fills your kitchen, the firm cloves that snap crisply when separated, and the incomparable flavor that store-bought varieties simply can’t match.

As an avid gardener who’s been growing garlic for over a decade, I can attest that this miraculous bulb is one of the most rewarding crops you can cultivate. Fall is the perfect time to plant garlic, setting the stage for a bountiful harvest next summer.

Whether you’re a novice gardener looking for an easy first crop or a seasoned grower aiming to expand your garlic repertoire, this comprehensive guide will walk you through everything you need to know about planting, growing, and harvesting exceptional garlic.

The Rich History of the “Stinking Rose”

Before we dig into the soil, let’s appreciate garlic’s remarkable journey through human history. Garlic has been used as both food and medicine since at least the 25th century BCE—around the time the pyramids were being constructed at Giza, Egypt.

Ancient Greek and Roman soldiers consumed garlic regularly, and by the mid-16th century, it was being grown in England.

Interestingly, modern English attitudes toward garlic were once quite cautious. As late as 1997, Dr. D.G. Hessayon warned in his bestselling book, The Vegetable & Herb Expert: “If you are a beginner with garlic, you must use it very sparingly or you will be put off forever.” How times have changed!

Today, garlic is one of the most universally accepted culinary ingredients, appreciated worldwide for its pungent flavor and incredible versatility.

My Garlic Growing Journey

I’ll never forget my first garlic harvest. After months of anticipation, I gently loosened the soil around those mysterious bulbs and pulled up my very first head of homegrown garlic.

The soil fell away to reveal a perfect white bulb with streaks of purple—so different from the uniform grocery store variety I was accustomed to. That evening, I roasted a few cloves with olive oil and spread them on crusty bread. The flavor was revelatory—sweeter, more complex, and infinitely more satisfying than any garlic I’d tasted before.

That first successful crop sparked what has become an annual tradition in my garden. Each year, I experiment with new varieties and techniques, expanding both my garden space and my knowledge.

The beauty of garlic is that each season teaches you something new, and the plant seems to adapt and improve over time when grown in the same garden—as if it’s learning alongside you.

Understanding Garlic Varieties

One of the first decisions you’ll need to make is which type of garlic to grow. There are hundreds of varieties worldwide, but they fall into two main categories: hardneck and softneck.

Hardneck Varieties

Hardneck garlic (Allium sativum var. ophioscorodon) is named for the rigid flowering stalk (or “scape”) that grows from the center of the plant. This stalk hardens as the plant matures, hence the name.

Advantages of hardneck garlic:

• More complex, robust flavor profiles
• Larger cloves that are easier to peel and prepare
• Better adaptation to cold climates (ideal for northern regions)
• Produces edible scapes in late spring, giving you an early garlic harvest
• Often contains more beneficial compounds than softneck varieties

Popular hardneck family groups:

• Rocambole: Easy to peel with excellent flavor, but shorter storage life
• Purple Stripe: Excellent for baking and roasting with a sweet, complex flavor
• Porcelain: Large cloves with strong flavor and good storage potential
• Marbled Purple Stripe: Beautiful streaked bulbs with rich flavor

Popular hardneck varieties:

• Music (a Porcelain type, excellent for northern climates)
• Spanish Roja (a Rocambole type, known for exceptional flavor)
• Chesnok Red (a Purple Stripe, perfect for roasting)
• German Extra Hardy (a Porcelain type with excellent cold tolerance)

The main drawback of hardneck varieties is their shorter storage life—typically 4-6 months under optimal conditions.

Softneck Varieties

Softneck garlic (Allium sativum var. sativum) is what you typically find in grocery stores. These varieties don’t produce a flowering stalk, resulting in soft, pliable stems that can be braided for storage.

Advantages of softneck garlic:

• Longer storage life (8-10 months when properly cured)
• Generally produces more cloves per bulb
• Better adapted to milder climates
• Can be beautifully braided for storage and display

Popular softneck family groups:

• Artichoke: Adaptable and productive with multiple layers of cloves
• Silverskin: Excellent storage capabilities and mild flavor

Popular softneck varieties:

• Inchelium Red (an Artichoke type, award-winning flavor)
• California Early (a reliable producer with good disease resistance)
• Silver White (a Silverskin type, excellent for braiding)
• Italian Loiacono (an Artichoke type with rich flavor)

Elephant Garlic

Despite its name and appearance, elephant garlic (Allium ampeloprasum) is not true garlic but rather a type of leek. It produces massive bulbs with a milder, sweeter flavor than true garlic. It’s grown in the same manner as regular garlic and makes an impressive addition to the garden, but don’t expect the same intensity of flavor.

Choosing the Right Variety for Your Garden

When selecting garlic for planting, consider:

1. Your climate: Hardneck varieties perform better in colder regions (Zones 3-6), while softneck varieties are better suited to milder climates (Zones 5-9).
2. Your culinary preferences: If you love roasting garlic or using it in robust dishes, hardneck varieties offer superior flavor. If you primarily use garlic in lighter dishes or want longer storage, softneck might be preferable.
3. Local adaptation: Whenever possible, source garlic that has been grown successfully in your region. Garlic adapts to local conditions over time, developing traits that help it thrive in your specific microclimate.
4. Source quality: Purchase seed garlic from reputable suppliers, local farmers, or garlic festivals rather than using supermarket garlic, which may have been treated to prevent sprouting and is likely not suited to your growing region.

Timing Your Fall Garlic Planting

Timing is crucial for successful garlic planting. The goal is to give garlic enough time to establish roots before winter without allowing it to produce significant top growth that could be damaged by severe cold.

Optimal Planting Windows

As a general rule, plant garlic 4-6 weeks before the ground freezes in your area. This typically translates to:

• Northern/colder regions (Zones 3-5): Plant between late September and late October
• Moderate climates (Zones 6-7): Plant in mid-October to early November
• Southern/milder regions (Zones 8-9): Plant in late October through November

A good rule of thumb is to plant about 2 weeks after the first fall frost but before the ground freezes solid. In most regions, this coincides with the time when the leaves of deciduous trees are changing color or falling.

What If You Miss the Optimal Window?

If you’ve missed the fall planting window, you have several options:

1. Plant anyway, if possible: As long as the ground isn’t frozen solid, you can still plant garlic. The bulbs might be smaller at harvest, but you’ll still get a crop.
2. Cold frame or container planting: Plant cloves in containers that can be kept in a protected area (like a cold frame or unheated garage) until spring.
3. Spring planting: While fall planting is ideal, you can plant garlic in early spring as soon as the ground is workable. Spring-planted garlic will produce smaller bulbs but still provides a harvest.
4. Refrigerate until spring: Store your seed garlic in the refrigerator (not the freezer) until earliest spring planting time. This provides the cold period (vernalization) that garlic needs for proper bulb development.

Preparing Your Garden Bed

Garlic thrives in well-prepared soil, and taking the time to create optimal growing conditions will significantly improve your harvest.

Soil Requirements

The ideal soil for growing garlic is:

• Well-draining: Garlic roots can rot in waterlogged soil
• Rich in organic matter: Provides nutrients and improves soil structure
• Slightly acidic to neutral pH: Aim for 6.0-7.0
• Loose and friable: Allows bulbs to expand easily

Step-by-Step Soil Preparation

1. Select the right location: Choose a sunny spot that receives at least 6-8 hours of direct sunlight daily. Garlic can tolerate partial shade but produces best in full sun.
2. Clear the area: Remove all weeds, rocks, and plant debris from your garden bed. Garlic doesn’t compete well with weeds, especially during its early growth stages.
3. Loosen the soil: Use a garden fork or broadfork to loosen the soil to a depth of 8-12 inches without turning it over (no-till method). This improves drainage and allows roots to penetrate easily.
4. Add organic matter: Incorporate 2-4 inches of well-rotted compost, aged manure, or leaf mold into the top 6 inches of soil. This adds nutrients and improves soil structure.
5. Adjust soil pH if necessary: Based on soil test results, add lime to raise pH or sulfur to lower it, aiming for the 6.0-7.0 range.
6. Add balanced fertilizer: Garlic is a heavy feeder. Work in a balanced organic fertilizer according to package directions. Some growers prefer to add:
   • Bone meal or rock phosphate for phosphorus (supports root development)
   • Crushed eggshells or gypsum for calcium
   • Wood ash (if soil is acidic) for potassium and trace minerals
7. Level the bed: Rake the surface smooth and remove any remaining debris.

Bed Layout Options

You can plant garlic in several configurations:

Traditional Rows:

• Space rows 12-24 inches apart
• Plant cloves 4-8 inches apart within rows
• Pros: Easier to weed and harvest, especially in larger gardens
• Cons: Less efficient use of space

Offset Grid Pattern:

• Plant cloves in a staggered grid, 6-8 inches apart in all directions
• Pros: Maximizes space utilization, good for small gardens
• Cons: Can be more difficult to weed between plants

Raised Beds:

• Especially beneficial in areas with heavy clay soil or poor drainage
• Create beds 6-8 inches high and 2-4 feet wide
• Plant in offset grid pattern for maximum efficiency
• Pros: Superior drainage, soil warms earlier in spring
• Cons: Requires more initial work to set up

The Planting Process

With your bed prepared and your garlic varieties selected, it’s time for the most enjoyable part—getting those cloves in the ground!

Selecting and Preparing Cloves

1. Break apart bulbs: Carefully separate the bulbs into individual cloves 1-2 days before planting. Keeping the paper husk intact protects the clove from disease and pests.
2. Select the best cloves: Choose the largest, firmest cloves for planting. Larger cloves generally produce larger bulbs. Set aside small or damaged cloves for kitchen use.
3. Optional soaking step: Some gardeners soak cloves in a solution of seaweed extract, compost tea, or a mixture of baking soda (1 tablespoon per gallon) and fish emulsion for 12-24 hours before planting. This can help with initial growth and disease prevention, but it’s not necessary for success.
4. Keep varieties separated and labeled: If you’re planting multiple varieties, keep them clearly labeled to avoid mixing them up.

Planting Tutorial

1. Make planting holes or furrows: Use your finger, a dibber, or a garden trowel to create holes approximately 2-3 inches deep (deeper in sandy soils, shallower in clay soils).
2. Place cloves properly: Set each clove in its hole with the pointed end up and the flat root end down. The tip of the clove should be 1-2 inches below the soil surface.
3. Space appropriately: Leave 4-8 inches between cloves, depending on variety and soil quality. Larger varieties and richer soil can accommodate wider spacing.
4. Cover carefully: Gently fill in the holes with soil and firm lightly. Avoid compacting the soil too much.
5. Mark rows and varieties: Use permanent markers to identify different varieties, particularly if you’re growing multiple types.
6. Water thoroughly: Give the newly planted garlic a good soaking to help settle the soil around the cloves and initiate root growth.

Mulching Your Garlic Bed

Mulching is especially important for fall-planted garlic. A good layer of mulch:

• Protects cloves from extreme temperature fluctuations
• Prevents frost heaving in winter
• Conserves moisture in spring and summer
• Suppresses weeds
• Adds organic matter to the soil as it breaks down

Recommended Mulching Materials:

• Straw (not hay, which contains seeds)
• Shredded leaves
• Pine needles
• Shredded bark
• Grass clippings (dried and seed-free)

Mulching Process:

1. Wait until after watering to apply mulch
2. Apply a 4-6 inch layer of mulch over the entire bed
3. In very cold regions, you may want to add additional mulch after the ground freezes
4. In spring, you can either:
   • Remove mulch entirely to allow soil to warm more quickly
   • Pull mulch away from emerging shoots but leave it between rows
   • Thin the mulch layer to 2-3 inches

Year-Round Garlic Care

Once your garlic is planted, most of the hard work is done. However, some regular maintenance throughout the growing season will ensure the best possible harvest.

Winter Care

In most regions, garlic needs little attention during winter. The mulch you applied at planting time provides all the protection it needs. If you live in an area with severe winters (Zone 3-4), you might consider adding another layer of mulch after the ground freezes for extra insulation.

Some garlic will send up shoots before winter arrives. Don’t worry if these get frost-killed—the plant will send up new shoots in spring. The important growth during fall and early winter is happening underground as the cloves develop strong root systems.

Spring Maintenance

As temperatures warm in spring, your garlic will begin active growth. Here’s how to care for it:

1. Adjust mulch: When shoots emerge, ensure they’re not struggling to push through thick mulch. Thin or redistribute mulch as needed.
2. Early fertilization: When plants reach about 6 inches tall, apply a nitrogen-rich fertilizer. Options include:
   • Diluted fish emulsion (following package directions)
   • Compost tea
   • Balanced organic fertilizer
   • A side dressing of composted manure
3. Weed control: Keep the garlic bed meticulously weeded, especially in early spring. Garlic doesn’t compete well with weeds.
4. Monitor for pests and disease: Check plants regularly for signs of yellowing, spots, or insect damage. Early intervention is crucial for managing problems.

Summer Care

As summer approaches, your garlic care routine shifts:

1. Manage scapes: Hardneck varieties will produce curly flower stalks (scapes) in late spring or early summer. Remove these when they form a complete curl but before they straighten out. This directs the plant’s energy to bulb development rather than seed production. Bonus: scapes are delicious in stir-fries, pesto, and many other dishes!
2. Watering schedule: Continue regular watering (about 1 inch per week) until about 2-3 weeks before harvest. Reduce watering at this point to allow bulbs to begin drying and to prevent disease.
3. Final fertilization: Apply a potassium-rich fertilizer in early summer to support bulb development. Avoid nitrogen-heavy fertilizers after early June, as they can delay bulb formation.
4. Pest management: Continue monitoring for pests and diseases. Common issues include:
   • Onion thrips (tiny insects that cause silvery streaking on leaves)
   • Leek moth (caterpillars that mine leaves and bulbs)
   • Garlic rust (orange pustules on leaves)
   • White rot (fungal disease affecting roots and bulbs)

Harvesting, Curing, and Storage

After months of anticipation, harvest time finally arrives, typically in late June to late July, depending on your climate and garlic variety.

When and How to Harvest

Signs that garlic is ready to harvest:

• The lower third to half of the leaves have turned yellow or brown
• Upper leaves are still green
• For hardneck varieties, scapes have straightened
• If you dig up a test bulb, the cloves fill out the skins and the wrappers have visible markings

Harvesting process:

1. Choose a dry day when soil is relatively dry
2. Loosen soil with a garden fork, starting several inches away from the plant
3. Gently lift bulbs from the soil without pulling on the stalk
4. Brush off excess soil but don’t wash the bulbs
5. Keep roots and leaves attached during the curing process
6. Handle bulbs gently to avoid bruising

The Curing Process

Proper curing is essential for flavor development and long-term storage:

1. Place harvested garlic in a single layer in a warm, dry, well-ventilated location out of direct sunlight. Good options include:
   • A covered porch
   • A garage with good airflow
   • A barn or shed
   • Hanging in bundles from rafters
   • Laid out on screens or mesh racks
2. Ensure good air circulation around all bulbs
3. Allow garlic to cure for 2-4 weeks, until:
   • The roots have dried and feel stiff
   • The outer wrappers are papery and dry
   • The necks have dried down completely
   • Leaves are completely dry
4. After curing, trim roots to ¼ inch from the bulb
5. For hardneck varieties, cut the stalks about 1-2 inches above the bulb
6. For softneck varieties, either trim the stalks or braid them for storage
7. Gently clean off any remaining soil by brushing with a soft cloth

Storage Methods for Longevity

The key to garlic storage is providing the right conditions: cool, dry, dark, and well-ventilated.

Optimal storage conditions:

• Temperature: 55-65°F (13-18°C)
• Humidity: 45-50%
• Good air circulation
• No direct sunlight

Storage methods:

1. Mesh bags: Allow airflow while protecting bulbs
2. Paper bags: Good option for smaller quantities
3. Braids (softneck only): Decorative and practical
4. Clay garlic keepers: Help maintain ideal humidity
5. Hanging baskets: Provide excellent ventilation

Avoid storing garlic:

• In the refrigerator (promotes sprouting)
• In plastic containers (traps moisture)
• Near apples or potatoes (ethylene gas can cause sprouting)

Saving Seed Stock for Next Season

To maintain or expand your garlic crop year after year:

1. Select the largest, most perfect bulbs during harvest
2. Cure these bulbs with extra care
3. Store them separately from your culinary garlic
4. Check periodically for any signs of sprouting or mold
5. Reserve about 1/4 of your harvest for replanting (depending on how much you want to grow next year)
