Yes — Strong Match
stock is grown as an annual, so season length decides it here, not a winter zone — and Georgia's typical season runs ~275 frost-free days against the ~50 stock needs.
Sow by about Sep 16
Stock is grown as an annual, so what decides it here is season length, not a winter zone. It needs about 50 frost-free days and a typical Georgia season runs ~275 frost-free days, leaving 225 days of slack. That is room to sow as late as about Sep 16 and still finish before the usual first freeze (Nov 30), or to run a second succession.

Your yard isn't the whole zone.
Stock is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical Georgia site runs ~275 frost-free days, but that is a state median, not your yard: slope, trees, and low spots move the last-frost date across a single parcel. Enter your address and we'll score stock against your land's actual frost dates, sun, and soil.

When to Plant Stock 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
Those dates are when stock goes out, not when it starts. It is sown under cover about 6 weeks ahead, so counting back from Georgia's late-side last freeze of Mar 10 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Days to maturity vs. the window
At 75 days to maturity (USDA PLANTS Database), counting from the last hard freeze it ripens with 184 days to spare even in Georgia's tightest freeze scenario — room for a later start or a second sowing.
Timing tuned to sub-state frost dates — Towns County, not the statewide average.

Growing Season Fit
Frost-free days
Stock wants 50+ 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
Stock needs ~600 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
Stock likes near-neutral soil (pH 6-7.5). 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 6.5 and 7 — 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
Georgia's soils run mostly loamy sand, but SSURGO maps the series, texture, and drainage under your exact parcel. What matters for stock is the horizon its roots actually work, not the surface. That map unit, not the state average, decides how stock performs.

What Else to Consider for Stock 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 stock here specifically
Stock needs pH 6.0–7.5; Georgia's dominant loamy sand soils may or may not deliver that, so your parcel's SSURGO map unit is the real test.
Start with a soil test on your own ground and adjust pH and texture to fit stock's 6.0–7.5 range. How to handle it →
What to actually do about these — and the constraints that apply to every Georgia grower, not just stock — 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 stock to your county's window, not the statewide date.
Stock needs about 50 days of frost-free season to complete its cycle. Even Towns County — Georgia’s shortest season at 204 frost-free days — clears that by 154 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 stock about 225 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"). Stock's 50-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
Stock draws honeybees, butterflies, and moths (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, stock 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.
Recommended Stock Varieties for Georgia
Georgia publishes no state variety trial for stock, so we won't invent a "best for Georgia" list. Choose types rated to your USDA hardiness zone (7a-9b), and confirm winter survival and drainage against your own parcel.
Georgia Cooperative Extension
For Georgia-specific cultivar recommendations, planting calendars, and pest pressure for stock, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Stock native to Georgia?
No — the USDA PLANTS Database lists Stock 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 Stock in Georgia
When can I plant Stock 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). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
Can Stock mature before first frost in Georgia?
Yes — Stock matures in 75 days (USDA PLANTS Database), and Georgia's dependable hard-freeze-free window runs 259 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 184 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Stock grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Stock carries a range of zones Data pending, 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). Stock needs 50+ 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 Stock native to Georgia?
No — the USDA PLANTS Database lists Stock 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 Stock in Georgia?
Stock prefers pH 6-7.5 and well (dry spells) drainage (Growable Ground Plant Database). 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.
Will Stock actually grow on my specific land in Georgia?
