Summerdale, Alabama, sits in USDA hardiness zone 9a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
The conditions favor artichoke, fig, california poppy, and cabbage, among others — though every individual site edits that list with its own soil, sun, and drainage.

What this means for growing in Summerdale
Each reading below is measured for Summerdale itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsSummerdale runs about 297 days between hard freezes (read from Baldwin County, the closest normal to Summerdale) — 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
MeasuredSummerdale 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 Summerdale is in
Summerdale sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Summerdale's own centroid rather than borrowed from Baldwin County.

Is it too late to plant in Summerdale?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 12 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 6 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Summerdale, Superfund runs higher than the national average — 4 sites within ~10 miles of Summerdale. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Summerdale
Everything above resolves to Summerdale as a whole — one PHZM band, read across 7K acres, with hard-freeze dates borrowed from Baldwin County’s record because no 30-year normal resolves at this town’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 town 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 Summerdale
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Baldwin 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 town grain anywhere on this page — there is no town-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 Summerdale
When does frost risk typically end in Summerdale?
The last hard freeze (28°F) in Summerdale typically lands around Feb 12, 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 5.
When is the first frost in Summerdale?
The first hard freeze (28°F) in Summerdale typically arrives around Dec 6, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 22, so the watching starts about Nov 6 — about 297 days after the spring freeze cleared.
How long is the growing season in Summerdale?
Measured between 28°F hard freezes, Summerdale sees about 297 frost-free days — roughly Feb 12 through Dec 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 5 to Nov 22, about 262 days.
Is the soil safe to grow vegetables in Summerdale?
The federal record around Summerdale is a meaningful one — 285 documented sites, mostly Underground Storage Tanks entries (159), the nearest Underground Storage Tanks record about 0.3 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 Summerdale?
From about Nov 6 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 6 (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 6. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
