Learn how to grow garlic at home — from choosing hardneck vs. softneck varieties and planting cloves in fall to harvesting, curing, and storing for months of homegrown flavor.
Homegrown garlic is in a completely different class from anything you’ll find in a grocery store. Fresh-cured hardneck garlic — rich, complex, and pungent in ways that commercially grown softneck varieties rarely match — is one of the most rewarding harvests in the entire vegetable garden. And growing it is remarkably simple: plant cloves in fall, mulch them for winter, and harvest in summer. That’s the essential arc of garlic growing.
Garlic is one of the few vegetables that is planted in fall rather than spring — a characteristic that makes it a perfect use of garden space after summer crops are cleared and beds would otherwise sit empty through winter. The long, cold winter actually works for you: garlic needs cold temperatures to develop properly, and the extended growing period produces the large, flavorful bulbs that make homegrown garlic so exceptional.
At Outz News Garden, Maria Walker walks you through the complete garlic growing guide — hardneck vs. softneck selection, fall planting technique, spring care, scape removal, harvesting at exactly the right stage, and curing for maximum flavor and long storage.

Hardneck vs. Softneck Garlic: The Most Important Choice
According to the University of Minnesota Extension, garlic (Allium sativum) is a close relative of onions and chives — a medicinal and culinary herb that forms bulbs separating into many cloves, each covered with a white, purplish, or pinkish papery sheath. The most important variety decision is between hardneck and softneck types.
Hardneck Garlic — Best Flavor, Shorter Storage
Hardneck garlic produces a stiff central flower stalk (the “neck”) and is the type preferred by most home gardeners and culinary enthusiasts for its superior flavor complexity. Hardneck cloves are larger, easier to peel, and offer a broader range of flavor profiles than softneck types — from mild and buttery to hot and complex.
Hardneck types include:
- Rocambole: considered the finest-flavored hardneck type — rich, complex, earthy flavor. Produces 8 to 12 cloves per bulb. Stores only 3 to 6 months. Best for fresh use and short-term storage.
- Porcelain: fewer but very large cloves (4 to 6 per bulb); strong, hot flavor; stores 6 to 8 months — longer than rocambole. Excellent varieties: Music, Georgian Fire.
- Purple Stripe: vivid purple-striped wrappers; excellent roasted flavor; good storage. Considered the most ancestral hardneck type.
Hardneck advantage: produces edible garlic scapes in late spring — a delicious bonus harvest before the main bulb harvest.
Softneck Garlic — Longer Storage, Milder Flavor
Softneck garlic lacks the central stalk of hardneck types and is the variety sold in most grocery stores. It produces more cloves per bulb (12 to 20), stores significantly longer (9 to 12 months), and adapts better to warmer climates where winters are mild.
Softneck types:
- Artichoke: the most widely grown commercial type; numerous overlapping cloves; milder flavor; stores exceptionally well
- Silverskin: the longest-storing type (up to 12 months); smallest cloves; the traditional type used for garlic braids
Choose hardneck if you’re in Zone 5 or colder, prioritize flavor, and plan to use garlic within 6 months. Choose softneck if you’re in Zone 7 or warmer or want the longest possible storage life.
Where to Buy Garlic for Planting
Always purchase garlic seed stock from garden centers, seed catalogs, or farmers’ markets — never from grocery store garlic, which is often treated with anti-sprouting compounds and may carry diseases not present in your garden soil. Certified disease-free seed garlic ensures the best possible start for your planting.
Order seed garlic early — quality varieties sell out quickly, often by September. Popular sources include local farmers’ markets (where you can taste varieties before buying), specialty seed companies, and online garlic farms that offer dozens of varieties unavailable anywhere else.
Site Selection and Soil Preparation
According to the University of Maryland Extension, garlic requires full sun of at least 6 hours per day (prefers 8 to 10 hours) and does not grow well in soils that are high in clay or compacted. It takes 250 to 270 days from fall planting to summer harvest — meaning the quality of the growing environment has a long time to affect the final bulb size and flavor.
Site Requirements
- Full sun — 6 to 8 hours minimum: garlic in shade produces small bulbs and is more susceptible to disease
- Well-draining soil: garlic bulbs sitting in waterlogged soil rot. If drainage is poor, plant in raised beds — they are ideal for garlic.
- Loose, fertile soil: University of Minnesota Extension specifies that garlic grows best in well-drained, moisture-retentive soil with pH between 6.0 and 7.0. Loosen soil to 12 inches deep and incorporate 3 to 4 inches of compost before planting.
- Avoid fresh manure: apply only well-composted organic matter — fresh manure promotes excessive leafy growth and can introduce pathogens
- Crop rotation: do not plant garlic (or other alliums — onions, leeks, chives) in the same bed two consecutive years to prevent disease and pest buildup
When and How to Plant Garlic
Timing — Fall Planting Is Essential
Garlic must be planted in fall — this is one of the few non-negotiable rules in vegetable gardening. University of Minnesota Extension explains that garlic is a slow-growing crop, and planting in fall allows it substantially more time to mature. The ideal planting window is within 2 weeks of the first fall frost — garlic needs time to develop a root system and begin to form a shoot before winter, but should not emerge significantly above soil before hard freezes arrive.
According to University of Minnesota Extension, garlic planted in September produces the biggest bulbs the following July. In most of the US, this means planting from mid-September through October — earlier in the North, later in the South.
Step-by-Step Planting
- Step 1 — Break bulbs into cloves: separate bulbs into individual cloves the day you plant. Do not separate earlier, as exposed cloves dry out and lose viability quickly. Keep the papery skin intact on each clove — never plant bare cloves.
- Step 2 — Select the largest cloves: large cloves produce large bulbs. Plant the biggest, most vigorous cloves from each bulb; save smaller cloves for cooking.
- Step 3 — Plant pointed end up: the pointed tip of each clove is the shoot end — it must point upward. Plant 1 to 2 inches deep in loose soil, 2 inches deep in sandy soil.
- Step 4 — Space correctly: space cloves 4 to 6 inches apart within rows; rows 12 to 18 inches apart. University of Maryland Extension specifies 6 inch spacing for hardneck types that produce larger bulbs.
- Step 5 — Cover and firm: cover with soil and firm gently to eliminate air pockets around the clove
- Step 6 — Water well: water thoroughly after planting to settle soil and initiate root development
- Step 7 — Mulch immediately: apply 3 to 4 inches of straw mulch over the entire planted area. University of Minnesota Extension specifically recommends giving recently planted garlic a warm blanket of straw to prevent damage from the cold and moderate soil temperature through winter.
Spring Care: From Emergence to Scape Removal
Spring Emergence
Garlic shoots typically emerge in early spring — sometimes even in late winter during mild spells. The green shoots are frost-hardy and can tolerate temperatures into the mid-20s°F without damage. Pull back the straw mulch gradually as shoots emerge; keep mulch between rows to conserve moisture and suppress the weeds that are garlic’s most significant competition.
Weed Control — Critical
University of Minnesota Extension is emphatic: unless you control weeds early, they can easily overtake young garlic plants. Garlic grows slowly and cannot compete well with aggressive weeds — particularly in spring when growth is just resuming. Keep beds meticulously weeded through spring, and apply mulch between rows immediately after any cultivation to suppress subsequent weed germination.
Fertilizing
Garlic is a moderate feeder that responds well to nitrogen in spring when active growth resumes:
- Side-dress with a balanced fertilizer or apply fish emulsion when shoots are 3 to 4 inches tall
- A second application 3 to 4 weeks later supports continued bulb development
- Stop all fertilizing by June 1 — late nitrogen fertilizing delays bulbing and reduces storage quality
Watering
Garlic needs consistent moisture from spring through early June, then relatively dry conditions as bulbs mature:
- Water to maintain consistent soil moisture through spring — approximately 1 inch per week
- Reduce watering in late June as foliage begins to yellow — this drying-down period is essential for bulb quality and storage life
- Stop watering completely 2 to 3 weeks before harvest
Garlic Scapes — Remove Them
Hardneck garlic produces a curling flower stalk called a scape in late spring or early summer. According to Penn State Extension, if the scape is allowed to develop, it will compete with the bulb for nutrients, resulting in a reduction in bulb size and quality. Remove scapes when they have completed one full curl — cut or snap them off at the base of the stalk.
Do not discard scapes — they are a genuine culinary delicacy. With a mild garlic flavor and crisp texture, garlic scapes are excellent sautéed, grilled, made into pesto, or used anywhere you would use green onions. They represent a bonus harvest several weeks before the main bulb harvest.
Harvesting Garlic at the Right Stage
Harvesting at exactly the right stage is critical for both flavor quality and storage life. Harvested too early, bulbs are underdeveloped; too late, and the wrappers split, dramatically shortening shelf life.
When to Harvest
University of Minnesota Extension specifies that depending on variety and climate zone, harvest garlic between late June and late July. The reliable indicators:
- Lower leaves have yellowed and browned; upper leaves are still green
- Roughly one-half of the total leaves have died back
- Dig a test bulb — it should be full-size with distinct, well-defined cloves separated by papery wrappers
A reliable rule of thumb: count the green leaves remaining on the plant. Each green leaf corresponds to a wrapper layer protecting the bulb. Harvesting when 5 to 6 leaves remain green means 5 to 6 wrapper layers — enough for good storage. Waiting until most leaves die back leaves too few wrappers and the bulb will not store well.
Harvesting Technique
- Loosen soil with a garden fork 4 to 6 inches from the base of the plant before lifting — never pull garlic straight up by its tops
- Lift gently to avoid bruising; every bruise becomes a potential rot entry point during curing
- Handle freshly harvested bulbs with care — the wrappers are still soft and damage easily
- Leave tops and roots intact at harvest — do not trim until after curing is complete
Curing and Storing Garlic
Curing is what transforms fresh-harvested garlic into the firm, dry, long-storing ingredient you use in the kitchen all year. University of Maryland Extension specifies that garlic should be cured by hanging in a warm (80°F), well-ventilated area for 3 to 8 weeks — the wide range depending on variety and conditions.
Curing Process
- Tie bulbs in bundles of 10 to 15 by their tops and hang in a warm, dry, well-ventilated location — a covered porch, shed, or garage works well
- Alternatively, lay bulbs in a single layer on wire mesh or screens in a shaded, airy location
- Keep out of direct sun — sunlight bleaches wrappers and can cause off-flavors
- Ensure excellent air circulation — poor airflow during curing causes mold
- Curing is complete when the necks are completely dry and the outer wrappers feel papery and crackle when touched
Trimming and Storing After Curing
- Trim roots close to the bulb base and cut tops ½ to 1 inch above the bulb neck
- Gently rub off the outermost wrapper layer to remove any remaining soil
- Store in mesh bags, paper bags, or open baskets in a cool (50 to 60°F), dry, dark, well-ventilated location
- Never refrigerate garlic — cold and moisture cause premature sprouting and flavor loss
- Storage life: rocambole 3 to 6 months; porcelain and purple stripe 6 to 8 months; softneck artichoke 9 to 12 months
- Save your best bulbs for replanting: University of Minnesota Extension notes that you can save garlic cloves from one crop to the next — keep the biggest cloves for planting the following fall
Quick-Reference Garlic Growing Tips
- Plant in fall, within 2 weeks of first frost — the most important timing rule
- Use certified seed garlic, not grocery store garlic
- Plant pointed end up, 1 to 2 inches deep
- Mulch immediately with 3 to 4 inches of straw
- Weed early and consistently — garlic cannot compete with weeds
- Remove hardneck scapes when fully curled — improves bulb size
- Harvest when half the leaves have died back
- Cure 3 to 8 weeks before trimming and storing
- Save your largest bulbs for next year’s seed stock
Learning how to grow garlic adds a genuinely exceptional ingredient to your kitchen that no store can match — richly flavored hardneck varieties with complexity and depth that commercial garlic simply doesn’t possess. The process is unhurried and satisfying: plant in the quiet of fall, tend through the long spring growing season, harvest in summer, and enjoy the fruits of your patience all year long.
Start with one variety of hardneck garlic — Music or Chesnok Red are excellent first choices — and a single 4×8 raised bed or a well-prepared row. The first summer you pull your own garlic from the garden, brush off the soil, and smell that unmistakable aroma, you’ll understand why serious cooks and gardeners consider homegrown garlic one of the most worthwhile projects in the entire vegetable garden.
