Published: April 24, 2026
Alabama gardeners in Zone 7b have a 38-week growing season for cabbage (March 1 to November 22). Alabama's spring and fall windows both work well for cabbage — some gardeners plant both successions for a long harvest. This guide gives exact dates for Alabama based on your local frost calendar.
Cabbage Planting Dates for Alabama
| Start seeds indoors | January 11–18 |
| Last frost (average) | March 1 |
| Transplant outdoors | February 8–18 |

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.
⚠ Start cabbage indoors 6–8 weeks before last frost. Transplant 2–4 weeks before last frost. Very frost tolerant — withstands temperatures as low as 20°F. Also plant in late summer for fall harvest.
Growing Cabbage in Alabama's Climate
Alabama's moderate Zone 7b climate is well-suited to cabbage 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 cabbage 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 cabbage pests to watch for in Alabama include Cabbage Worm and Cabbage Looper. The first line of defense is companion planting: Onion and Dill 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.

Cabbage Growing Tips for Alabama Gardeners
- •Space plants 18 inches apart — crowding reduces head size and promotes fungal disease.
- •Side-dress with nitrogen 3–4 weeks after transplanting to support rapid leaf formation.
- •Alabama's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
- •Harvest when heads feel firm; leave the root ball in the ground and small secondary heads may form.
