Alabama is not one climate
Alabama’s winter-low ladder runs across 67 counties, from zone 7.5 in Jackson County to zone 9 in Mobile County. That is 15°F between the two counties’ average coldest night — the difference between blueberry overwintering in the ground and coming under cover.
The middle half of 67 counties runs 8–8.5 zones, with a median of 8.5 zones — a 1.5-zone span end to end.
Measured across 67 Alabama 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 Alabama Fits Best
Blueberry is rated for zones 3–8 — a cold floor USDA puts at -40 to -30°F. Against Alabama’s 67 counties that band holds in 33 of them, and the line runs at Jackson County (zone 7b), 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 Alabama's zones 7b-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for blueberry (USDA PHZM 2023):

When to Plant Blueberry in Alabama
The frost window
Across Alabama, the last spring hard freeze (28°F) clears between Feb 24 and Mar 16, and the first fall hard freeze lands between Nov 15 and Nov 28 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 244-day window you can count on — up to 277 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
Alabama runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for blueberry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether blueberry is a permanent planting or a replant-every-spring crop for you turns on your own zone within Alabama; 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 blueberry survives winter in part of Alabama, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Growing degree days
Blueberry needs ~1500 GDD (base 50°F) to ripen. We haven't confirmed this against a published source yet. The state median runs ~5383 GDD (from PRISM 1991-2020 climate normals), so Alabama's typical season clears that easily.
Chill hours
Blueberry requires ~800 chill hours (32-45°F dormancy window). Alabama typically banks ~1226 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
Blueberry prefers acidic soil (pH 3-5.5). Alabama's red clay can run on the acidic side, which often aligns well — confirm with a soil test before planting. It will grow across that whole span, but it does best between pH 4 and 5.5 — worth knowing before you decide whether a Alabama soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Alabama site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. Preferred pH: We haven't confirmed this against a published source yet.

Before you plant blueberry 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 blueberry goes in. What follows is Alabama’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 Alabama — and how to grow with it.
We checked the federal record across Alabama — 20,346 documented sites across 7 of the 8 source types we track.
The most significant on record: 327 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Alabama 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 of imported, lab-tested soil grow well almost anywhere in the meantime.

What Else to Consider for Blueberry in Alabama
Zone compatibility tells you about winter cold survival — but Alabama growers also need to think about:
Heavy clay soils in the Piedmont region
High humidity promotes fungal diseases
Fire ants are a persistent garden pest
What to actually do about these — and the constraints that apply to every Alabama grower, not just blueberry — is covered on the Alabama growing guide.
Where in Alabama Blueberry Is Zone-Hardy
Blueberry is rated for USDA zones 3–8. 33 of Alabama’s 67 counties fall inside that band. The coldest that does is Jackson County at zone 7b. 34 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Alabama decides this one.
Across those 67 counties Alabama’s winter-low ladder runs from zone 7b in Jackson County to zone 9a in Mobile County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Marion County holds its last hard freeze (28°F) until about Mar 28, while Mobile County is clear by Feb 9 — 47 days apart. Set blueberry out on your county’s date, not the state’s.

Pollinator + Wildlife Value
Blueberry draws honeybees and native bees (high value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, blueberry can only work that bloom inside Alabama's frost window — roughly 266 days, opening after the last 28°F freeze (Feb 24 - Mar 16) and closing at the first (Nov 15 - Nov 28), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Common Questions About Growing Blueberry in Alabama
When can I plant Blueberry in Alabama?
Alabama's last spring hard freeze (28°F) clears between Feb 24 and Mar 16, and the first fall hard freeze lands between Nov 15 and Nov 28 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Blueberry, so this page does not state whether it overwinters in Alabama 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 Blueberry grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Blueberry carries a range of zones 3-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Alabama site have?
A typical Alabama site sees ~266 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Blueberry needs 160+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Blueberry native to Alabama?
Yes — the USDA PLANTS Database (accessed 2026-10-19) records Blueberry in Alabama, and Kew's Plants of the World Online (WCVP) lists Alabama in its native range. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Blueberry in Alabama?
Blueberry prefers pH 3-5.5 and well (dry spells) drainage (FAO ECOCROP). Most Alabama soils run mildly acidic to neutral; many sites land near this band naturally, and a soil test plus targeted sulfur or organic amendment closes any gap.
Will Blueberry actually grow on my specific land in Alabama?
