Georgia is not one climate
Georgia’s winter-low ladder runs across 159 counties, from zone 7.5 in Fannin County to zone 9 in Worth County. That is 15°F between the two counties’ average coldest night — the difference between upland cotton overwintering in the ground and coming under cover.
The middle half of 159 counties runs 8–9 zones, with a median of 8.5 zones — a 1.5-zone span end to end.
Measured across 159 Georgia counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Georgia Fits Best
Upland Cotton is rated for zones 8–11 — a cold floor USDA puts at 10 to 20°F. Against Georgia’s 159 counties that band holds in 152 of them, and the line runs at Banks County (zone 8a), the coldest county still inside it.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Georgia's zones 7a-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for upland cotton (USDA PHZM 2023):

When to Plant Upland Cotton in Georgia
The frost window
Across Georgia, the last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 259-day window you can count on — up to 290 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Georgia runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for upland cotton, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether upland cotton is a permanent planting or a replant-every-spring crop for you turns on your own zone within Georgia; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says upland cotton survives winter in part of Georgia, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Upland Cotton wants 150+ frost-free days; a typical Georgia site sees ~275 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Chill hours
Upland Cotton has no winter-chill requirement — its listed minimum is 0 hours (Growable Ground Plant Database). Georgia typically banks ~1015 chill hours per winter (from PRISM 1991-2020 climate normals), so chill is not a constraint on this plant here — and not evidence in its favour either. Winter survival and season length are what decide it.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Upland Cotton tolerates a wide pH range (pH 5-9.5) — 4.5 units, acid ground through alkaline — so soil acidity is rarely what limits it in Georgia. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 6 and 7.5 — worth knowing before you decide whether a Georgia soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Georgia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Plant pH requirements: FAO ECOCROP and USDA PLANTS, with the remaining rows from other published sources or Growable Ground compilation. Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Georgia soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.
What Else to Consider for Upland Cotton in Georgia
Zone compatibility tells you about winter cold survival — but Georgia growers also need to think about:
Heavy red Piedmont clay is difficult to work and drains poorly
High humidity drives fungal diseases in summer
Fire ants are a persistent pest in gardens across the state
Summer heat (90-100F) can stress cool-season crops by May
What to actually do about these — and the constraints that apply to every Georgia grower, not just upland cotton — is covered on the Georgia growing guide.
Timing shifts within Georgia
Upland Cotton needs about 150 days of frost-free season to complete its cycle. Even Towns County — Georgia’s shortest season at 204 frost-free days — clears that by 54 days, so season length isn’t the constraint anywhere in Georgia. What varies is your own parcel.
Across Georgia’s 159 counties the frost-free season runs from 204 days in Towns County to 305 days in Colquitt County — a spread of 101 days, which is why a single statewide planting date misleads. The median Georgia county sees 275 frost-free days, leaving upland cotton about 125 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Upland Cotton's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Upland Cotton draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, upland cotton can only work that bloom inside Georgia's frost window — roughly 275 days, opening after the last 28°F freeze (Feb 17 - Mar 10) and closing at the first (Nov 24 - Dec 4), per NOAA Regional Climate Centers ACIS, 1991-2020.

Is Upland Cotton native to Georgia?
Upland Cotton is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Georgia. It can still earn a place in a Georgia garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Upland Cotton in Georgia
When can I plant Upland Cotton in Georgia?
Georgia's last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Upland Cotton, so this page does not state whether it overwinters in Georgia and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Upland Cotton grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Upland Cotton carries a range of zones 8-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Georgia site have?
A typical Georgia site sees ~275 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Upland Cotton needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Upland Cotton native to Georgia?
Upland Cotton is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Georgia. It can still earn a place in a Georgia garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Upland Cotton in Georgia?
Upland Cotton tolerates pH 5-9.5 and well (dry spells) drainage (FAO ECOCROP). That is a 4.5-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Georgia site — amend for drainage and organic matter first.
