What this means for growing in Underwood-Petersville
Each reading below is measured for Underwood-Petersville itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredUnderwood-Petersville runs about 247 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

Winter hardiness
MeasuredUnderwood-Petersville sits in USDA hardiness zone 8a.
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 Underwood-Petersville
Every plant below cleared Underwood-Petersville's own zone 8a and its 247-day season. Each card opens that plant's Alabama profile. How we score.






























Is it too late to plant in Underwood-Petersville?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 13; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 13 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 15 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

A note from Gnorman
What an experienced grower watches for around here
In and around Underwood-Petersville, Superfund runs higher than the national average — 14 sites within ~10 miles of Underwood-Petersville. 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 Underwood-Petersville
Everything above resolves to Underwood-Petersville as a whole — one PHZM band and one 28°F frost record, read across 4K 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 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 Underwood-Petersville
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 Underwood-Petersville’s own record; 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 Underwood-Petersville
When does frost risk typically end in Underwood-Petersville?
The last hard freeze (28°F) in Underwood-Petersville typically lands around Mar 13, 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 Apr 3.
When is the first frost in Underwood-Petersville?
The first hard freeze (28°F) in Underwood-Petersville typically arrives around Nov 15, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 1, so the watching starts about Oct 16 — about 247 days after the spring freeze cleared.
How long is the growing season in Underwood-Petersville?
Measured between 28°F hard freezes, Underwood-Petersville sees about 247 frost-free days — roughly Mar 13 through Nov 15, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 3 to Nov 1, about 212 days.
Is the soil safe to grow vegetables in Underwood-Petersville?
The federal record around Underwood-Petersville is a meaningful one — 590 documented sites, mostly Underground Storage Tanks entries (354), the nearest Underground Storage Tanks record about 0.5 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 Underwood-Petersville?
From about Oct 16 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 Nov 15 (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 Nov 15. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
