Autauga County, in Alabama, sits in USDA hardiness zone 8b — a zone band wide enough that plant choice, not possibility, is the interesting question.
A short list that earns its place here — cabbage, fig, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.

Heat and winter chill in Autauga County
Across a year, Autauga County accumulates about 5,462 growing degree days above 50°F, about 178 more than the middle Alabama county — ahead of 41 of Alabama’s 67 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 1,031 hours below 45°F, 217 fewer than the Alabama middle of 1,248. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Autauga County
Across Autauga County, the ground is predominantly Ultisols, where Smithdale, Heidel, and Luverne are the most extensive named soil series. The soil is generally well drained with a fine sandy loam surface. Topsoil pH runs about 5.0–5.3, strongly acidic. Rainfall drains through hydrologic group A soils.

How the ground varies across Autauga County
The USDA soil survey maps 76% of Autauga County as well drained — but another 22% drains differently: 10% poorly drained, 8% somewhat excessively drained.
Smithdale is the most extensive named soil at 16% of mapped acres, then Heidel (10%) and Luverne (9%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Autauga County
Each reading below is measured for Autauga County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Autauga County are well drained, in hydrologic group A — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Autauga County runs about pH 5.0–5.3, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredAutauga County runs about 278 days between hard freezes — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredAutauga County sits in USDA hardiness zone 8b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

What Grows in Autauga County
We scored all 1,086 plants against Autauga County's own USDA zone 8b and its own 278-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Alabama profile.
Is it too late to plant in Autauga County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 23 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 28 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

What the federal record shows across Autauga County — and how to grow with it.
We checked the federal record across Autauga County — 199 documented sites across 7 of the 9 source types we track.
The most significant on record: 1 Superfund site (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Autauga County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

What an experienced grower watches for around here
In and around Autauga County, two things run higher than the national average across Autauga County — PFAS (3 sites) and Underground Storage Tanks (125 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Autauga County
Everything above resolves to Autauga County as a whole — one PHZM band and one county frost record, read across 380K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at county scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better county average.

How we know this about Autauga County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Autauga County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Autauga County
When does frost risk typically end in Autauga County?
The last hard freeze (28°F) in Autauga County typically lands around Feb 23, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Mar 16.
How long is the growing season in Autauga County?
Measured between 28°F hard freezes, Autauga County sees about 278 frost-free days — roughly Feb 23 through Nov 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 16 to Nov 14, about 243 days.
Is the soil safe to grow vegetables in Autauga County?
The federal record around Autauga County is a meaningful one — 199 documented sites, mostly Underground Storage Tanks entries (125), the nearest Underground Storage Tanks record about 2.1 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
Everything above is measured at Autauga County's scale — its 8b band and its 278-day season. Your yard writes its own version of Autauga County's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
