Kanawha County, in West Virginia, sits in USDA hardiness zone 7a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Growers here do well with apple, ramp, pawpaw, and sugar maple — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Kanawha County lies within Appalachia — a regional growing area with its own character.

Is it too late to plant in Kanawha County?
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 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 8 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.
Growing Challenges in West Virginia
What an experienced grower plans around here — each one has a move.
Steep terrain limits usable growing area
Grow with the hill, not against it — terraced beds turn slopes into some of the best-drained ground there is, and your extension office has terracing guidance for exactly this country.
Thin acidic soils over shale bedrock
A soil test shows exactly how thin and how acid — then lime, compost, and built-up beds put depth where shale left none.
Short mountain valley growing seasons
Valley frost pockets shorten the season — fast varieties and a cold frame give the weeks back.
For cultivar selection, pest pressure, and planting-time guidance specific to West Virginia, the WVU Extension is the authoritative local source.
Safe to Grow Here?
What the federal record shows across Kanawha County — and how to grow with it.
We checked the federal record across Kanawha County — 1,552 documented sites across 6 of the 9 source types we track.
The most significant on record: 16 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Kanawha County carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

Know Before You Grow
- •Underground tanks can leak petroleum products. Soil testing near former gas stations is recommended.
- •Raised beds with imported soil can reduce exposure risk near brownfield sites.
- •Test well water for nitrates if you rely on a private well. Levels above 10 mg/L require treatment.

Frequently Asked Questions
What hardiness zone is Kanawha County, West Virginia?
Kanawha County sits in USDA hardiness zone 7a, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in Kanawha County?
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 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 8 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.
When does frost risk typically end in Kanawha County?
The last hard freeze (28°F) in Kanawha County typically lands around Mar 8, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in Kanawha County?
Measured between 28°F hard freezes, Kanawha County sees about 264 frost-free days — roughly Mar 8 through Nov 27, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in Kanawha County?
Kanawha County's zone 7a supports a wide range — strong performers include Apple, Ramp, Pawpaw, Sugar Maple, and Ginseng. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Kanawha County, really?
Officially, Kanawha County sits in USDA zone 7a (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Kanawha County?
The federal record around Kanawha County runs heavier than most — 1,552 documented sites — 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.
Just moved to Kanawha County — what should I know before planting?
Start with three facts. Kanawha County sits in USDA zone 7a, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 8, with about 264 frost-free days to work with (NOAA 1991–2020 climate normals); and 1,552 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
