Pevely, Missouri, sits in USDA hardiness zone 7a — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, cabbage, hazelnut, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Pevely, 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 Pevely 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 Pevely
Each reading below is measured for Pevely itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredPevely runs about 225 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredPevely sits in USDA hardiness zone 7a.
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 Pevely is in
Pevely sits in the Ozark Highlands — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Pevely's own centroid rather than borrowed from Jefferson County.

Is it too late to plant in Pevely?
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 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 5 — 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.

What an experienced grower watches for around here
In and around Pevely, two things run higher than the national average within ~10 miles of Pevely — PFAS (9 sites) and Nitrate (134 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.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Pevely
Everything above resolves to Pevely as a whole — one PHZM band and one 28°F frost record, read across 3K 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 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 Pevely
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 Pevely’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 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 Pevely
When does frost risk typically end in Pevely?
The last hard freeze (28°F) in Pevely typically lands around Mar 25, 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 15.
When is the first frost in Pevely?
The first hard freeze (28°F) in Pevely typically arrives around Nov 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 22, so the watching starts about Oct 6 — about 225 days after the spring freeze cleared.
How long is the growing season in Pevely?
Measured between 28°F hard freezes, Pevely sees about 225 frost-free days — roughly Mar 25 through Nov 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 15 to Oct 22, about 190 days.
Is the soil safe to grow vegetables in Pevely?
The federal record around Pevely runs heavier than most — 433 documented sites, mostly Underground Storage Tanks entries (177), the nearest Underground Storage Tanks record under a tenth of a mile out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do I protect my plants from frost in Pevely?
From about Oct 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 Nov 5 (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 5. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Pevely's scale — its 7a band and its 225-day season. Your yard writes its own version of Pevely's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
