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

Tennessee is mostly USDA zone 7a (range 6a-8a). Dates below are derived from peas's frost tolerance and Tennessee's frost window — not generic national averages.

Peas planting timetable for Tennessee

Stage	When in Tennessee	Anchor
Direct-sow outside	mid-March (March 11)	35 days before the last frost (mid-April)
First harvest (estimate)	mid-May (May 15)	~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 Tennessee's climate shifts the peas dates

Tennessee's last spring frost averages mid-April and first fall frost late October, which sets the whole planting clock. Tennessee has a long, humid, warm season with mild winters. The eastern mountains run a zone cooler than the western lowlands. 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 mid-April — a hard freeze can still set young plants back. In the eastern Appalachian highlands (zone 6a) the safe date runs a week or two later.

Regional variation within Tennessee

the eastern Appalachian highlands (zone 6a) runs roughly 1-2 weeks behind the state average; the western Mississippi lowlands near Memphis (zone 8a) can plant 1-2 weeks earlier.

Nashville — USDA zone 7b
Memphis — USDA zone 8a
Knoxville — USDA zone 7b
Chattanooga — USDA zone 7b

What else to plant in Tennessee around then

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

Frequently asked questions

When is the best time to plant peas in Tennessee?

In Tennessee (mostly USDA zone 7a), direct-sow peas mid-March (before the last frost, mid-April), and harvest from mid-May. 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 Tennessee?

Most of Tennessee sits in USDA hardiness zone 7a, with the state spanning roughly 6a-8a from the eastern Appalachian highlands (zone 6a) to the western Mississippi lowlands near Memphis (zone 8a). The last spring frost averages mid-April and the first fall frost late October.

Can you grow peas in Tennessee?

Yes. Tennessee's dominant zone 7a 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 Tennessee?

the eastern Appalachian highlands (zone 6a) runs roughly 1-2 weeks behind the state average; the western Mississippi lowlands near Memphis (zone 8a) can plant 1-2 weeks earlier.

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

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