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 concord grape 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
Concord Grape is rated for zones 4–8 — a cold floor USDA puts at -30 to -20°F. Against Georgia’s 159 counties that band holds in 44 of them, and the line runs at Fannin County (zone 7b), the coldest county still inside it.

Too little winter chill rather than too much cold — a low-chill selection is what changes 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 concord grape (USDA PHZM 2023):

When to Plant Concord Grape 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 concord grape, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether concord grape 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.
Timing tuned to sub-state frost dates — Towns County, not the statewide average.
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 concord grape 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
Concord Grape 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.
Growing degree days
Concord Grape needs ~2200 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.
Chill hours
Concord Grape requires ~600 chill hours (32-45°F dormancy window). Georgia typically banks ~1015 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
Concord Grape likes near-neutral soil (pH 4.9-7.5). That's the common-ground band across Georgia's red clay (piedmont) and sandy loam (coastal plain) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 6.5 — 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.
Your land, not the state average
SSURGO maps about 20.4% of Georgia as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Concord Grape sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

Before you plant concord grape 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 concord grape 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.

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 Concord Grape 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
Growing concord grape here specifically
Concord Grape rates to USDA zones 4–8 and takes frost damage on growing tissue around 32°F (FAO ECOCROP), but cold isn't the risk in Georgia — wet is: with roughly 20.4% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give concord grape a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Georgia grower, not just concord grape — is covered on the Georgia growing guide.
Timing shifts within Georgia
Georgia isn't one climate. In Towns County, the last hard freeze (28°F) holds until about Apr 7 — roughly 39 days later than the recorded state median — so plant concord grape to your county's window, not the statewide date.
Concord Grape 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 concord grape 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"). Concord Grape's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Good to Know Before You Plant Concord Grape
Concord Grape is listed as toxic to dogs (fruit) at a severe level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.
Georgia Cooperative Extension
For Georgia-specific cultivar recommendations, planting calendars, and pest pressure for concord grape, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Concord Grape native to Georgia?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Concord Grape as native to Georgia. Planting it supports the pollinators and wildlife that evolved alongside it.

What pests threaten concord grape in Georgia?
Spotted lanternfly and Japanese beetle are documented in Georgia, and they hit concord grape where it counts. Here is what each one actually does — and the move that beats it.
Spotted lanternfly
Act on thisGrapevines are one of only three plants spotted lanternfly is known to kill — Penn State Extension reports that scientists have seen it kill only grapevines, tree-of-heaven and black walnut saplings. On a vine, the sap feeding itself is the damage.
What to do: Scrape or smash every egg mass you can reach between September and June — Penn State found that more effective than the oil ovicides sold for the job. Scout your own vines through the season and treat only where high populations persist, and never spray a vine that is in bloom.
Documented range: states with established spotted lanternfly populations · Penn State Extension
Japanese beetle
Worth watchingThis is on the University of Minnesota's list of Japanese beetle preferred plants — but their read is that fruits, vegetables and herbs tolerate limited leaf feeding, and that in most cases the damage is cosmetic and will not kill the plant.
What to do: Protect it only through the few peak weeks: handpick into soapy water in the cool of morning, harvest regularly through July and August to take the feeding pressure off the edible parts, and keep the plant well watered — a vigorous plant outgrows feeding that looks worse than it is. Do not hang a beetle trap.

Common Questions About Growing Concord Grape in Georgia
When can I plant Concord Grape 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 Concord Grape, 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 Concord Grape grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Concord Grape carries a range of zones 4-8, 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). Concord Grape needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Towns, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Concord Grape native to Georgia?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Concord Grape as native to Georgia. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Concord Grape in Georgia?
Concord Grape prefers pH 4.9-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Georgia soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
