When to plant winter squash in Georgia — sow, transplant & harvest dates

Georgia is mostly USDA zone 8a (range 6b-9a). Dates below are derived from winter squash's frost tolerance and Georgia's frost window — not generic national averages.

Winter squash planting timetable for Georgia

Stage	When in Georgia	Anchor
Start seeds indoors	mid-March (March 15)	3 weeks before the last frost (early April)
Transplant outside	mid-April (April 19)	14 days after the last frost (early April)
First harvest (estimate)	late July (July 23)	~95 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 Georgia's climate shifts the winter squash dates

Georgia's last spring frost averages early April and first fall frost early November, which sets the whole planting clock. Georgia runs from cool mountains to a warm coastal plain, with a long humid season. Most of the state gardens in zone 8. Wait for warm soil — winter squash stall in cold ground even after the air warms, so don't rush them out.

Winter squash (butternut, acorn, delicata, Hubbard) requires 85-110 frost-free days from transplant; plan backward from the first fall frost date before seeding. Minimum soil temperature is 18 °C (65 °F); seeds rot in cold, wet soil. Short-season gardeners in zones 3-4 benefit from a 2-3 week indoor start in biodegradable pots to avoid transplant shock to the taproot. Curing harvested fruit at 27-30 °C for 10-14 days extends storage life.

Frost-risk note

Don't plant before early April — even a light frost will kill seedlings overnight. In the Blue Ridge mountains in the north (zone 6b) the safe date runs a week or two later.

Regional variation within Georgia

the Blue Ridge mountains in the north (zone 6b) runs roughly 1-2 weeks behind the state average; the Atlantic coast around Savannah (zone 9a) can plant 1-2 weeks earlier.

Frequently asked questions

When is the best time to plant winter squash in Georgia?

In Georgia (mostly USDA zone 8a), sow winter squash indoors around mid-March, transplant outdoors mid-April (after the last frost, early April), and harvest from late July. Winter squash are frost-tender — a single light frost kills seedlings, so they only go outside once frost danger has fully passed and the soil is warm.

What USDA zone is Georgia?

Most of Georgia sits in USDA hardiness zone 8a, with the state spanning roughly 6b-9a from the Blue Ridge mountains in the north (zone 6b) to the Atlantic coast around Savannah (zone 9a). The last spring frost averages early April and the first fall frost early November.

Can you grow winter squash in Georgia?

Yes. Georgia's dominant zone 8a supports winter squash — the key is timing. Winter squash are frost-tender — a single light frost kills seedlings, so they only go outside once frost danger has fully passed and the soil is warm.

Does the planting date change across Georgia?

the Blue Ridge mountains in the north (zone 6b) runs roughly 1-2 weeks behind the state average; the Atlantic coast around Savannah (zone 9a) can plant 1-2 weeks earlier.

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

Pair the post-frost slot with other warm-season crops — peppers, beans, squash, and cucumbers.
