Pelham, Alabama, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
Growers here do well with artichoke, fig, california poppy, and cabbage — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Pelham, 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 Pelham 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 Pelham
Each reading below is measured for Pelham itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsPelham runs about 281 days between hard freezes (read from Shelby County, the closest normal to Pelham) — 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
MeasuredPelham 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 Pelham is in
Pelham sits in the Ridge and Valley — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Pelham's own centroid rather than borrowed from Shelby County.

Is it too late to plant in Pelham?
For most of the year, no — what changes is which crops still fit the days remaining. 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 Dec 1 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

Your land is one point inside Pelham
Everything above resolves to Pelham as a whole — one PHZM band, read across 25K acres, with hard-freeze dates borrowed from Shelby 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 Pelham
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 Shelby 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 Pelham
When does frost risk typically end in Pelham?
The last hard freeze (28°F) in Pelham 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.
When is the first frost in Pelham?
The first hard freeze (28°F) in Pelham typically arrives around Dec 1, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 17, so the watching starts about Nov 1 — about 281 days after the spring freeze cleared.
How long is the growing season in Pelham?
Measured between 28°F hard freezes, Pelham sees about 281 frost-free days — roughly Feb 23 through Dec 1, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 16 to Nov 17, about 246 days.
Is the soil safe to grow vegetables in Pelham?
The federal record around Pelham is a meaningful one — 680 documented sites, mostly Underground Storage Tanks entries (352), the nearest PFAS record under a tenth of a mile 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 Pelham?
From about Nov 1 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 1 (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 1. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Pelham's scale — its 9a band and its 281-day season. Your yard writes its own version of Pelham's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
