What sets planting dates in Alabama
Planting dates across Alabama anchor to two dates. Most of the state sits in climate zone 3, where the average last spring frost lands around Mar 10 and the first fall frost around Nov 25 — a growing season of roughly 260 days. Every crop in the calendar counts forward or backward from those two frosts.
Hardy crops shrug off a light freeze, so they go in weeks before the last frost; tender crops wait until after it, once the soil warms. In Alabama's zone 3, that's why peas can go out around Feb 3 while tomatoes wait until about Mar 24.
Alabama isn't a single climate — it spans zones 2, 3, so higher-elevation and northern areas run later than these zone-3 dates. Use this as the state midpoint, then enter your ZIP for frost dates tuned to your exact area.
What sets your dates
| Factor | Effect on timing |
|---|---|
| Last spring frost | Tender crops can't go out until it passes — around Mar 10 in Alabama's zone 3 |
| First fall frost | Sets the harvest deadline — around Nov 25 — for anything still in the ground |
| Climate zone | Alabama spans zones 2, 3; colder (higher-number) areas run later |
| Crop hardiness | Hardy crops plant before the last frost; tender crops wait until after it |
| Indoor head start | Warm-season crops (tomatoes, peppers, basil) need 6–10 weeks started indoors first |
| Microclimate & elevation | Cold pockets, slopes, and higher ground run later than the state average |

Alabama planting tips
- Don't rush tender crops out before Alabama's last frost (around Mar 10) — a single late freeze can wipe out tomatoes and peppers.
- Start cool-season crops (peas, spinach, lettuce) early; they handle Alabama's spring chill and bolt once summer heat arrives.
- Count backward from Mar 10 to time indoor seed-starting — 6–10 weeks for warm crops that need a head start.
- For a fall harvest, work back from the first frost (around Nov 25) using each crop's days-to-harvest so it matures in time.
