When to plant peas in Alabama — sow, transplant & harvest dates

Alabama is mostly USDA zone 8a (range 7a-9a). Dates below are derived from peas's frost tolerance and Alabama's frost window — not generic national averages.

Peas planting timetable for Alabama

Stage	When in Alabama	Anchor
Direct-sow outside	mid-February (February 18)	35 days before the last frost (late March)
First harvest (estimate)	late April (April 24)	~65 days from direct sow

Dates are state-wide averages for the dominant zone. Local microclimates — elevation, urban heat, coastal moderation — can shift the window by 1-2 weeks. Use the frost-date calculator for a date tuned to your town.

Why Alabama's climate shifts the peas dates

Alabama's last spring frost averages late March and first fall frost early November, which sets the whole planting clock. Alabama has a long, hot, humid growing season with mild winters. Heat and humidity, not cold, are the main limits for most of the state. Sow early — peas bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Peas are the classic early-spring crop — direct-sow 4-6 weeks before the last spring frost, as soon as soil can be worked. They quit producing once daytime temperatures consistently hit 24 °C, so the sooner they go in, the longer the harvest window.

Frost-risk note

Don't plant before late March — a hard freeze can still set young plants back. In the northern Appalachian foothills (zone 7a) the safe date runs a week or two later.

Regional variation within Alabama

the northern Appalachian foothills (zone 7a) runs roughly 1-2 weeks behind the state average; the Gulf Coast around Mobile (zone 9a) can plant 1-2 weeks earlier.

Birmingham — USDA zone 8a
Montgomery — USDA zone 8b
Mobile — USDA zone 9a
Huntsville — USDA zone 7b
Tuscaloosa — USDA zone 8a

Frequently asked questions

When is the best time to plant peas in Alabama?

In Alabama (mostly USDA zone 8a), direct-sow peas mid-February (before the last frost, late March), and harvest from late April. Peas are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

What USDA zone is Alabama?

Most of Alabama sits in USDA hardiness zone 8a, with the state spanning roughly 7a-9a from the northern Appalachian foothills (zone 7a) to the Gulf Coast around Mobile (zone 9a). The last spring frost averages late March and the first fall frost early November.

Can you grow peas in Alabama?

Yes. Alabama's dominant zone 8a supports peas — the key is timing. Peas are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

Does the planting date change across Alabama?

the northern Appalachian foothills (zone 7a) runs roughly 1-2 weeks behind the state average; the Gulf Coast around Mobile (zone 9a) can plant 1-2 weeks earlier.

What else can I plant in Alabama around the same time?

The same early window suits peas, lettuce, spinach, and onion sets.
