When to plant lettuce in Mississippi — sow, transplant & harvest dates

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

Lettuce planting timetable for Mississippi

Stage	When in Mississippi	Anchor
Start seeds indoors	late February (February 25)	4 weeks before the last frost (late March)
Transplant outside	early March (March 4)	21 days before the last frost (late March)
First harvest (estimate)	late April (April 23)	~50 days from transplant

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 Mississippi's climate shifts the lettuce dates

Mississippi's last spring frost averages late March and first fall frost early November, which sets the whole planting clock. Mississippi has a hot, humid, long season with mild winters. The Gulf Coast is nearly frost-free; the north sees a short cold spell. Sow early — lettuce bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Lettuce is genuinely cold-hardy — direct-sow as soon as soil can be worked, 2-4 weeks before the last spring frost. It bolts and turns bitter in summer heat above 24 °C, so southern zones grow it as a winter and shoulder-season crop instead of in midsummer.

Frost-risk note

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

Regional variation within Mississippi

the northern hill country near Tupelo (zone 7b) runs roughly 1-2 weeks behind the state average; the Gulf Coast around Gulfport (zone 9a) can plant 1-2 weeks earlier.

Jackson — USDA zone 8b
Gulfport — USDA zone 9a
Hattiesburg — USDA zone 8b
Tupelo — USDA zone 8a

What else to plant in Mississippi around then

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

Frequently asked questions

When is the best time to plant lettuce in Mississippi?

In Mississippi (mostly USDA zone 8b), sow lettuce indoors around late February, transplant outdoors early March (before the last frost, late March), and harvest from late April. Lettuce 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 Mississippi?

Most of Mississippi sits in USDA hardiness zone 8b, with the state spanning roughly 7b-9a from the northern hill country near Tupelo (zone 7b) to the Gulf Coast around Gulfport (zone 9a). The last spring frost averages late March and the first fall frost early November.

Can you grow lettuce in Mississippi?

Yes. Mississippi's dominant zone 8b supports lettuce — the key is timing. Lettuce 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 Mississippi?

the northern hill country near Tupelo (zone 7b) runs roughly 1-2 weeks behind the state average; the Gulf Coast around Gulfport (zone 9a) can plant 1-2 weeks earlier.

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

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