Chickasaw, Alabama, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Well-matched crops include artichoke, fig, california poppy, and cabbage, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Chickasaw, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Chickasaw lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Chickasaw
Each reading below is measured for Chickasaw itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsChickasaw runs about 297 days between hard freezes (read from Mobile County, the closest normal to Chickasaw) — 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.

Winter hardiness
MeasuredChickasaw sits in USDA hardiness zone 9a.
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.

The kind of country Chickasaw is in
Chickasaw sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Chickasaw's own centroid, and it is not what its county reads: Mobile County is mostly Southeastern Plains. The wider page above you is answering a different question about different ground.

Is it too late to plant in Chickasaw?
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 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 3 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

Your land is one point inside Chickasaw
Everything above resolves to Chickasaw as a whole — one PHZM band, read across 3K acres, with hard-freeze dates borrowed from Mobile County’s record because no 30-year normal resolves at this city’s own centroid. 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 city 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 local average.

How we know this about Chickasaw
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Mobile County’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at city grain anywhere on this page — there is no city-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Chickasaw
When does frost risk typically end in Chickasaw?
The last hard freeze (28°F) in Chickasaw typically lands around Feb 9, 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 2.
When is the first frost in Chickasaw?
The first hard freeze (28°F) in Chickasaw typically arrives around Dec 3, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 19, so the watching starts about Nov 3 — about 297 days after the spring freeze cleared.
How long is the growing season in Chickasaw?
Measured between 28°F hard freezes, Chickasaw sees about 297 frost-free days — roughly Feb 9 through Dec 3, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 2 to Nov 19, about 262 days.
Is the soil safe to grow vegetables in Chickasaw?
The federal record around Chickasaw is a meaningful one — 1,318 documented sites, mostly Underground Storage Tanks entries (690), the nearest Brownfields record about 0.2 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.
How do I protect my plants from frost in Chickasaw?
From about Nov 3 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 3 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 3. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
