Published: April 24, 2026

Bean Planting Dates for Alabama
| Start seeds indoors | Year-round |
| Last frost (average) | March 1 |
| Direct sow outdoors | March 8–18 |
| Expect first harvest | April 27 – May 12 |
| Fall crop start | September 13–23 |

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.
⚠ Direct sow beans after last frost when soil reaches 60°F. Never start indoors — beans resent transplanting. Succession plant every 2–3 weeks for continuous harvest.
Growing Beans in Alabama's Climate
Alabama's moderate Zone 7b climate is well-suited to bean 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 bean 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 bean pests to watch for in Alabama include Mexican Bean Beetle and Aphid. The first line of defense is companion planting: Corn and Cucumber 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.

Bean Growing Tips for Alabama Gardeners
- •Inoculate bean seeds with rhizobium bacteria before planting in new garden soil — boosts nitrogen fixation and yields.
- •Plant bush beans every 2–3 weeks through midsummer for a continuous harvest from July to first frost.
