When to plant sweet potatoes in Georgia — sow, transplant & harvest dates

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

Sweet potatoes planting timetable for Georgia

Stage	When in Georgia	Anchor
Start seeds indoors	late February (February 22)	6 weeks before the last frost (early April)
Transplant outside	late April (April 26)	21 days after the last frost (early April)
First harvest (estimate)	early August (August 9)	~105 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 sweet potatoes 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 — sweet potatoes stall in cold ground even after the air warms, so don't rush them out.

Sweet potatoes are extremely frost-tender and demand warm soil — do not transplant slips until soil temperature at 4-inch depth holds at 18 °C (65 °F) or above, typically 3 weeks after the last spring frost. Short-season zones (z5-6) should start slips indoors under lights 5-6 weeks early to ensure 100-120 frost-free days. Avoid zones 3-4 without a floating row cover season-extension strategy; in z9-11 slips can go out as early as late March.

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.

Atlanta — USDA zone 8a

Frequently asked questions

When is the best time to plant sweet potatoes in Georgia?

In Georgia (mostly USDA zone 8a), sow sweet potatoes indoors around late February, transplant outdoors late April (after the last frost, early April), and harvest from early August. Sweet potatoes 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 sweet potatoes in Georgia?

Yes. Georgia's dominant zone 8a supports sweet potatoes — the key is timing. Sweet potatoes 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.
