When to Plant Garlic in Alabama
Published: April 21, 2026
Alabama gardeners in Zone 7b grow garlic on the opposite calendar from most vegetables: plant cloves in October or November and harvest the following summer. This guide provides Alabama-specific planting and harvest dates and the state's specific cold-hardening needs.
Garlic Planting Dates for Alabama
| Last frost (average) | March 1 |
| Direct sow outdoors | October–November (plant cloves) |
| Expect first harvest | June (following year) – July (following year) |
| First fall frost (average) | November 22 |
Dates above assume Zone 7b, the most common zone in Alabama. Gardeners in cooler Birmingham (Zone 7b) plant 1–2 weeks later; warmer Montgomery (Zone 8a) can plant 1–2 weeks earlier.
⚠ PLANTING SEASON IS OPPOSITE: Plant garlic cloves in fall (October–November) for harvest the following summer (June–July). This is unlike any other common vegetable.
Growing Garlic in Alabama's Climate
Alabama's moderate Zone 7b climate is well-suited to garlic with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your garlic harvest significantly in Alabama. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common garlic pests to watch for in Alabama include Thrips and White Rot. The first line of defense is companion planting: Tomato and Rose planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.

Garlic Growing Tips for Alabama Gardeners
- •Plant individual cloves in October–November, pointed end up, 2 inches deep, 6 inches apart.
- •Mulch with 3–4 inches of straw after the first hard freeze to insulate through winter.
- •Alabama's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
- •Remove garlic scapes (the curling flower stalks) in June from hardneck varieties to redirect energy to the bulb.

In Alabama's moderate climate, planting garlic with Tomato and Rose helps deter pests and improve soil. Avoid planting near Bean and Pea, which inhibit garlic growth through root chemistry or shared pest pressure. See the full garlic companion planting guide for the complete list.
