One warm-season crop
Plant in spring and leave room for a long finish
The chart supplies a two-month Middle Georgia window and no fall alternative. The crop guide adds the 70°F soil threshold and a 90–120 day harvest horizon.
Supported outdoor window
April 15 – June 15
Middle Georgia range for plants; use slips rather than true seed.Fall planting
Not recommended
The current UGA chart does not provide a second crop window.Soil warmth gives a better regional answer
South can reach 70°F weeks before northern Georgia
The crop guide supplies more useful regional timing than a simple date shift: mid-April can work in South Georgia, while middle and northern areas may not reach the threshold until early May.
North Georgia
Expect the 70°F soil threshold later, often in the first part of May or beyond.
A long-season cultivar still needs time to finish before the first frost.Middle Georgia
Use April 15–June 15, but wait for 70°F soil.
Early May is the crop guide’s general expectation for the middle to northern part of the state.South Georgia
Soil can reach 70°F around mid-April.
Measure the bed rather than treating mid-April as a guaranteed statewide date.Warm soil and a long runway
Confirm the start and the finish
Sweet potatoes need heat at planting and enough warm days to reach harvest before cold soil lowers quality.
- Soil at planting depth has reached 70°F.
- You have healthy slips from a dependable source, not true seed.
- The variety’s 90–120 day timeline fits before the expected first frost.
- The site drains well and receives 8–10 hours of sunlight.
Plant rooted slips
Treat sweet potatoes as plants, not seed potatoes
Choose a cultivar by maturity
UGA examples range from about 90 days to 120 days, which changes the latest sensible date.
Buy healthy slips
Garden-center slips are usually easier to establish and more likely to be disease resistant.
Wait for 70°F soil
Use a soil reading to decide when the regional spring window truly opens.
Leave room for vines
UGA’s home-garden guide uses about 3 feet between slips.
Calendar and maturity must agree
A June date is not equally good for every variety
The chart stays open through June 15, but a 120-day cultivar planted late needs a different frost calculation than a 90-day cultivar.
Window open, soil cold
Wait for 70°F
The crop-specific soil threshold is the deciding condition.Warm soil, 90-day variety
More late-window margin
Confirm that 90 days still finish before the expected frost.Warm soil, 120-day variety
Plant earlier in the window
Longer maturity makes a late June start less forgiving.After June 15
Do not substitute a fall crop
UGA does not recommend a separate fall window for Middle Georgia.Harvest boundary
Finish before frost and cold soil
UGA says to harvest before the first frost; cool soil reduces quality and storage life. This is why the variety timeline belongs in the planting decision.
