Grant County, in West Virginia, sits in USDA hardiness zone 6b — a zone band wide enough that plant choice, not possibility, is the interesting question.
A short list that earns its place here — cabbage, blackberry, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Grant County lies within the Allegheny Highlands and Appalachia — a regional growing area with its own character.

Heat in Grant County
Across a year, Grant County accumulates about 2,530 growing degree days above 50°F, about 480 fewer than the middle West Virginia county — ahead of 6 of West Virginia’s 55 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.

Soil in Grant County
Across Grant County, the ground is predominantly Inceptisols, where Berks, Weikert, and Dekalb are the most extensive named soil series. The soil is generally well drained with a channery silt loam surface. Topsoil pH runs about 4.6–5.5, very strongly acidic. Rainfall drains through hydrologic group B soils.

How the ground varies across Grant County
The USDA soil survey maps 75% of Grant County as well drained — but another 22% drains differently: 13% moderately well drained, 3% somewhat poorly drained.
Berks is the most extensive named soil at 20% of mapped acres, then Weikert (11%) and Dekalb (7%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Grant County
Each reading below is measured for Grant County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Grant County are well drained, in hydrologic group B — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Grant County runs about pH 4.6–5.5, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredGrant County runs about 178 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredGrant County sits in USDA hardiness zone 6b.
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 Grant County is in
Grant County spans 2 EPA Level III ecoregions — Ridge and Valley (74%) and Central Appalachians (27%). Which one your land falls in changes what grows wild there and how the ground behaves, and a county-wide answer cannot tell you which.
What Grows in Grant County
We scored all 1,086 plants against Grant County's own USDA zone 6b and its own 178-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's West Virginia profile.
Is it too late to plant in Grant 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 Mar 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 23 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 18 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

Safe to Grow Here?
What the federal record shows across Grant County — and how to grow with it.
We checked the federal record across Grant County — 161 documented sites across 6 of the 9 source types we track.
The most significant on record: 1 Superfund site (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Grant County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

What an experienced grower watches for around here
In and around Grant County, Underground Storage Tanks runs higher than the national average — 108 sites across Grant County. That's not a problem with your land — it's information about it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Grant County
Everything above resolves to Grant County as a whole — one PHZM band and one county frost record, read across 306K 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 county 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 county average.

How we know this about Grant County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Grant County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Grant County
When does frost risk typically end in Grant County?
The last hard freeze (28°F) in Grant County typically lands around Apr 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 May 14.
How long is the growing season in Grant County?
Measured between 28°F hard freezes, Grant County sees about 178 frost-free days — roughly Apr 23 through Oct 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 14 to Oct 4, about 143 days.
Is the soil safe to grow vegetables in Grant County?
The federal record around Grant County is a meaningful one — 161 documented sites, mostly Underground Storage Tanks entries (108), the nearest Brownfields record about 1.6 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.
