Unlikely — Zone Mismatch
mamey (zones 11-12) does not overlap with Alabama's zone range (7b-9b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Mamey is hardy to zone 11, and the warmest ground in Alabama is zone 9 — 2 zones short. Planted in open ground it will not survive a Alabama winter. To grow it here, grow mamey in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

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 mamey 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.

Where Mamey Stands in Alabama
Mamey is rated for zones 11–12 — a cold floor USDA puts at 40 to 50°F. No Alabama county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Alabama winters, not about mamey.

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.

When to Plant Mamey 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 mamey, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether mamey 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.
Timing tuned to sub-state frost dates — Marion 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.
Soil + Drainage Fit
Mamey likes near-neutral soil (pH 5.5-8). That's the common-ground band across Alabama's red clay and sandy loam — 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 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.
Your land, not the state average
SSURGO maps about 14.1% of Alabama as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Mamey tolerates drought well, so wet feet — not dry spells — is its real risk here — your soil map unit, not the state average, is the real answer.

Before you plant mamey 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 mamey 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 Mamey 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
Growing mamey here specifically
Mamey likes pH 5.5–8.0 and its growing tissue burns around 32°F (FAO ECOCROP), yet neither saves it from wet feet — SSURGO maps about 14.1% of Alabama poorly-drained, where its crown sit and rot.
Set mamey high on bermed, grit-amended ground so winter and storm water drain away from the crown. How to handle it →
What to actually do about these — and the constraints that apply to every Alabama grower, not just mamey — is covered on the Alabama growing guide.
Timing shifts within Alabama
Alabama isn't one climate. In Marion County, the last hard freeze (28°F) holds until about Mar 28 — roughly 26 days later than the recorded state median — so plant mamey to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in Alabama Mamey Is Zone-Hardy
Mamey is rated for USDA zones 11–12. No Alabama county reaches it. Even Mobile County, the state’s mildest winter at zone 9a, sits below the plant’s zone 11 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
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. None of that range reaches the band mamey needs, so here the statewide answer really is the answer.

Ceiling: our plant database.. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Mamey draws honeybees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, mamey 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.
Alabama Cooperative Extension
For Alabama-specific cultivar recommendations, planting calendars, and pest pressure for mamey, the canonical source is Alabama Cooperative Extension System. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Mamey native to Alabama?
No — the USDA PLANTS Database lists Mamey as introduced rather than native in the Lower 48, so it is not part of Alabama's native flora. It grows here as a garden plant; pairing it with a few Alabama natives keeps local pollinators fed too.
Looking for plants that belong here? The Alabama growing guide lists plants that USDA PLANTS records growing in Alabama and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.

Common Questions About Growing Mamey in Alabama
When can I plant Mamey 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 Mamey, 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 Mamey grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Mamey is listed for zones 11-12, which do not overlap them, so there is no zone in Alabama where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.
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). Mamey 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 Marion, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Mamey native to Alabama?
No — the USDA PLANTS Database lists Mamey as introduced rather than native in the Lower 48, so it is not part of Alabama's native flora. It grows here as a garden plant; pairing it with a few Alabama natives keeps local pollinators fed too.
How should I amend the soil for Mamey in Alabama?
Mamey prefers pH 5.5-8 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Alabama soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Mamey actually grow on my specific land in Alabama?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores mamey against your address's mapped soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
