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 garlic 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.

When to Plant Garlic 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.
When to start the seed
Garlic is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Georgia's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
Establishment timing
As a long-lived plant, garlic isn't racing the calendar to a harvest date. Plant it in spring once the last hard-freeze window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
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 garlic survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Garlic wants 90+ frost-free days; a typical Georgia site sees ~275 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Garlic needs ~1200 GDD (base 50°F) to ripen. The state median runs ~5616 GDD (from PRISM 1991-2020 climate normals), so Georgia's typical season clears that easily.
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
Garlic tolerates a wide pH range (pH 5-8.5) — 3.5 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 6.6 — 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.

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.
Before you plant garlic for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before garlic goes in. What follows is Georgia’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Georgia — and how to grow with it.
We checked the federal record across Georgia — 37,000 documented sites across 8 of the 9 source types we track.
The most significant on record: 521 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Georgia carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

Highest-Severity Sites
A note from Gnorman
What an experienced grower watches for around here
In and around Georgia, two things run higher than the national average across Georgia — Superfund (521 sites) and Underground Storage Tanks (24,572 sites). That's not a problem with your land — it's information about it.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Garlic 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 garlic — is covered on the Georgia growing guide.
Timing shifts within Georgia
Garlic needs about 90 days of frost-free season to complete its cycle. Even Towns County — Georgia’s shortest season at 204 frost-free days — clears that by 114 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 garlic about 185 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"). Garlic's 90-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
Garlic draws honeybees, native bees, and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, garlic 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. Deer pressure is meaningful across much of Georgia; garlic is listed as deer-resistant (USDA PLANTS Database), which makes it a safer pick for unfenced sites. Our deer & wildlife guide carries the full deer-resistant list and how to protect the rest.
Georgia Cooperative Extension
For Georgia-specific cultivar recommendations, planting calendars, and pest pressure for garlic, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Garlic native to Georgia?
No — the USDA PLANTS Database lists Garlic as introduced rather than native in the Lower 48, so it is not part of Georgia's native flora. It grows here as a garden plant; pairing it with a few Georgia natives keeps local pollinators fed too.

Common Questions About Growing Garlic in Georgia
When can I plant Garlic 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). Garlic is a long-lived planting, so target spring just after your local last hard freeze — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Garlic grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Garlic carries a range of zones 2-10, 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). Garlic needs 90+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Garlic native to Georgia?
No — the USDA PLANTS Database lists Garlic as introduced rather than native in the Lower 48, so it is not part of Georgia's native flora. It grows here as a garden plant; pairing it with a few Georgia natives keeps local pollinators fed too.
How should I amend the soil for Garlic in Georgia?
Garlic tolerates pH 5-8.5 and well (dry spells) drainage (FAO ECOCROP). That is a 3.5-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.
