Tennessee is one of the best states in the country for growing garlic — and one of the most misunderstood. Spanning USDA zones 5b through 7b, Tennessee offers a wide range of growing conditions depending on where you live. East Tennessee's mountain valleys behave very differently from the warm, humid lowlands of West Tennessee. Get the timing and variety selection right, and you'll pull some of the most beautiful garlic bulbs you've ever seen.
At Garlic Gods, we grow our seed garlic right here in Tennessee. This isn't generic advice — it's what we've learned from years of planting, harvesting, and perfecting our craft in Tennessee soil.
Tennessee's Garlic Growing Zones
- East Tennessee (Knoxville, Chattanooga, Appalachian highlands): Zones 6a–7a. Cooler winters, more reliable cold for hardneck varieties.
- Middle Tennessee (Nashville, Murfreesboro, Columbia): Zone 6b–7a. Excellent all-around garlic country — both hardneck and softneck perform well.
- West Tennessee (Memphis, Jackson): Zone 7a–7b. Warmer winters favor softneck and Creole varieties.
When to Plant Garlic in Tennessee
The ideal planting window for most of Tennessee is mid-October through mid-November. You want soil temperatures between 50–65°F — warm enough for roots to establish, cool enough to begin vernalization.
- East Tennessee (zones 6a–7a): October 10–November 1 — Best Garlic Varieties for Zone 6 · Zone 7
- Middle Tennessee (zones 6b–7a): October 15–November 10 — Best Garlic Varieties for Zone 6 · Zone 7
- West Tennessee (zones 7a–7b): October 20–November 20 — Best Garlic Varieties for Zone 7
A good rule of thumb: plant garlic about 4–6 weeks before your first hard freeze. In Nashville, that's typically around November 15. In Knoxville, closer to November 5. In Memphis, late November.
Tennessee's fall season is prime garlic planting time — raised beds with good drainage are ideal in the state's clay-heavy soils
Hardneck or Softneck? What Grows Best in Tennessee
Tennessee's middle zones make it one of the few states where you can successfully grow both hardneck and softneck varieties — which is great news for garlic lovers.
Hardneck Varieties (Best for East and Middle Tennessee)
If you're in the cooler parts of the state — East Tennessee or the higher elevations of Middle Tennessee — hardneck varieties will reward you with exceptional flavor and the bonus of garlic scapes in late spring.
- Music — Our most popular hardneck. Porcelain type, zones 3–8, jumbo cloves, rich strong flavor. Performs beautifully across all of Tennessee.
- Chesnok Red — Purple Stripe, sweet when roasted, one of the best baking garlics available. Our best-producing hardneck year after year.
- German Red — Rocambole type, bold and spicy, 8–10 large cloves. Excellent in East Tennessee's cooler zones.
- Russian Red — Marbled Purple Stripe, large bulbs, tolerant of moisture — great for Tennessee's sometimes wet springs.
Softneck Varieties (Best for Middle and West Tennessee)
Softnecks are more forgiving of Tennessee's variable winters and store significantly longer than hardnecks — often 9–12 months. If you're in West Tennessee or want maximum storage life, go softneck.
- Inchelium Red — Taste-test champion, zones 5–10, very large bulbs. One of the most adaptable varieties for Tennessee's range of conditions.
- Messidor — French white softneck, mild and balanced flavor, large uniform bulbs. Excellent storage and adaptability — a great all-purpose kitchen garlic for Middle and West Tennessee.
- Castano — Artichoke softneck, bold and savory flavor, reliable producer. Thrives in Tennessee's warmer zones and ideal for braiding.
- Morado — Spanish Creole, intensely flavored, ideal for West Tennessee's warmer winters.
How to Plant Garlic in Tennessee
- Prepare your bed: Garlic loves well-drained soil with plenty of organic matter. Work in compost before planting. Tennessee's clay-heavy soils benefit from raised beds or added grit for drainage.
- Break your bulbs: Separate cloves just before planting — don't do this days in advance. Plant the largest cloves for the largest bulbs.
- Plant depth and spacing: Plant cloves 2 inches deep, pointed end up, 6 inches apart in rows 12 inches apart.
- Mulch immediately: Apply 3–4 inches of straw mulch right after planting. Tennessee winters can swing dramatically — mulch protects roots during cold snaps and retains moisture during dry spells.
- Fertilize in spring: When green shoots emerge (usually February–March in Tennessee), apply a nitrogen-rich fertilizer to support leaf development. Stop fertilizing by May to let the plant focus on bulb development.
Common Garlic Mistakes in Tennessee
- Planting too late: Many Tennessee gardeners wait until December. By then, roots don't have time to establish before the coldest weather hits. Aim for mid-October to mid-November.
- Skipping mulch: Tennessee's freeze-thaw cycles can heave cloves right out of the ground. Mulch is not optional here.
- Choosing the wrong variety: Planting a cold-climate hardneck in West Tennessee often leads to disappointment. Match your variety to your zone.
- Watering in late spring: Stop watering about 2–3 weeks before harvest. Wet soil at harvest time leads to poor curing and shorter storage life.
When to Harvest Garlic in Tennessee
Tennessee garlic typically harvests in late May through late June, depending on your location and variety:
- East Tennessee: Mid-June to late June
- Middle Tennessee: Late May to mid-June
- West Tennessee: Late May to early June
Watch for the lower leaves to begin browning — when about half the leaves are brown and half are still green, it's time to harvest. Don't wait too long or the wrappers will deteriorate in the ground.
Curing and Storing Your Tennessee Garlic

After harvest, hang or lay your garlic in a warm, dry, well-ventilated space for 3–4 weeks. Tennessee's summer humidity can be a challenge — a barn, covered porch, or garage with good airflow works well. Avoid direct sunlight, which can bleach the wrappers and reduce storage life.
Once cured, hardnecks will store 4–8 months. Softnecks will store 9–12 months in a cool, dry location.
