The Kanawha / Ohio Valley (Metro Valley) spans USDA hardiness zones 6b-7a — a zone band wide enough that plant choice, not possibility, is the interesting question.
West Virginia's warmest, longest-season ground: the Ohio and Kanawha river bottoms run a full hardiness zone warmer than the 6b ridges that hem them in — USDA zone 7a with roughly 215–223 frost-free days from Wayne and Cabell up through Kanawha and Putnam (county_data.json). This is the thermal belt where Charleston, Huntington, and Parkersburg sit, and where most of the state's gardeners actually grow. Expect a spring that opens weeks ahead of the highlands and a fall that holds past the first ridge frosts. Expect apple, pawpaw, sugar maple, and ramp to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.

Hardiness Zone Range
What Grows in the Kanawha / Ohio Valley (Metro Valley)
Plants matched to the Kanawha / Ohio Valley (Metro Valley)'s USDA zones 6b-7a, ordered by how much hardiness margin each has across the region — the ones with room to spare at both ends of this band lead. Each links to its full growing profile.
Native Plants of the Kanawha / Ohio Valley (Metro Valley)
Plants the USDA PLANTS Database documents as native and present in this region’s state, kept only where the published hardiness range meets the Kanawha / Ohio Valley (Metro Valley)’s USDA zones 6b-7a — closest range match first. Presence is recorded by state, so a plant can be documented across the state and still be scarce in your corner of the region.
The ground across the Kanawha / Ohio Valley (Metro Valley)
The USDA soil survey maps this ground county by county. These are those records weighted by land area across six member counties — this region’s own profile, not a state figure.
The ground is predominantly Ultisols, at 46% of mapped acres, followed by Alfisols (31%), Inceptisols (17%) and Entisols (6%). Five soil orders appear somewhere inside the footprint, which is the honest reason a regional soil answer only goes so far. The most extensive named soils are Gilpin, Upshur, and Dekalb.
84% of those acres are well drained, and another 9% moderately well drained, 1% poorly drained. Topsoil pH runs 4.6–5.5 between the lowest and the highest county on record. 6% of the footprint is classed prime farmland.

What this means for growing in the Kanawha / Ohio Valley (Metro Valley)
The soil survey reads this ground county by county, and the readings above are those records summed across the Kanawha / Ohio Valley (Metro Valley). Here is what they mean for a garden here — and the move an experienced grower makes about each one.
Drainage
From county records84% of the mapped acres across the Kanawha / Ohio Valley (Metro Valley) are well drained — ground that drains quickly. That is area-weighted across all six of its mapped counties.
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
From county recordsTopsoil across the Kanawha / Ohio Valley (Metro Valley) runs pH 4.6–5.5 — acidic in all six of them.
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.

What the federal record shows across the Kanawha / Ohio Valley (Metro Valley) — and how to grow with it.
Across the Kanawha / Ohio Valley (Metro Valley)'s 6 counties the federal record holds 3,890 documented sites, mostly Underground Storage Tanks (1,997), Brownfields (1,264) and Nitrate (432). The heaviest single county is Kanawha County, with 1,552.
That is a regional count, not a reading of any one lot — proximity to a documented site is information, not a diagnosis. Open the map outlined to the Kanawha / Ohio Valley (Metro Valley) to see which records sit where you actually grow.

Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

Everything above resolves to the Kanawha / Ohio Valley (Metro Valley) as a whole — a footprint spanning USDA zones 6b-7a. Your parcel sits in exactly one of them. 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 region 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 regional average.

The boundary: a cluster of neighboring counties. Growing regions have no official boundary, so this footprint is our published one, and every figure on this page was measured over the counties inside it rather than borrowed from the state around it.
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, aggregated across the footprint; the growing season from NOAA Regional Climate Centers ACIS 1991–2020 28°F normals, read at each member’s own record; boundaries from US Census TIGER/Line 2025; the contamination record from the federal sources named in that beat above; the soil from the USDA NRCS SSURGO survey, read at each member county’s own record and weighted to this footprint by land area. Where a member carries no record of its own, it is absent from the figure rather than filled in.
Common questions about the Kanawha / Ohio Valley (Metro Valley)
What hardiness zone is the Kanawha / Ohio Valley (Metro Valley)?
The Kanawha / Ohio Valley (Metro Valley) spans USDA hardiness zones 6b-7a, aggregated from the USDA Agricultural Research Service Plant Hardiness Zone Map 2023 across the region's counties. Zones reflect average annual extreme minimum temperatures from 1991–2020 data.
How long is the growing season in the Kanawha / Ohio Valley (Metro Valley)?
Measured between 28°F hard freezes, the Kanawha / Ohio Valley (Metro Valley)'s counties mostly run 216 to 221 frost-free days, median 218 (NOAA Regional Climate Centers ACIS, 1991–2020, over 6 member counties). That 5-day spread is the honest read — no single season describes 6 counties, and each county guide below carries its own.
When does frost risk end in the Kanawha / Ohio Valley (Metro Valley)?
Across the Kanawha / Ohio Valley (Metro Valley), the middle half of member counties see their last 28°F hard freeze between Mar 31 and Apr 3 (median Apr 2), and their first fall freeze between Nov 5 and Nov 7. Those are hard freezes, not the last light frost: tender transplants wait for about Apr 23, and elevation decides which end of a 3-day spread you garden in.
What grows well in the Kanawha / Ohio Valley (Metro Valley)?
The Kanawha / Ohio Valley (Metro Valley)'s conditions suit plants such as Apple, Pawpaw, Sugar Maple, Ramp, Ginseng. What actually thrives on any one site still turns on its specific soil, sun, and drainage — we score each plant against the real conditions at your address.
How is the Kanawha / Ohio Valley (Metro Valley) defined?
The Kanawha / Ohio Valley (Metro Valley) is defined here as a curated cluster of 6 neighboring counties that share a growing character. Growing regions have no official boundary, so this footprint is our published one — every county in it is named on this page.

Other growing regions across West Virginia
The vast eastern mountain region of steep hollows, thin acidic soils, and short upland seasons — apples, brambles, ramps, and forest crops on hard-won ground. (Union of the core Appalachian ecoregions.)
West Virginia's coldest, highest corner: the Monongahela high country around Canaan Valley, Davis, Snowshoe, and Spruce Knob (4,863 ft, the state's highest point). Frost lingers into early May (last frost near DOY 106-120) and the season runs just ~170-193 days in USDA zone 6a-6b, so the palette here is genuinely short-season and cold-hardy, a world apart from zone 7a Charleston (frost-free by ~DOY 91).
West Virginia's warmest, earliest-spring corner. The three-county Eastern Panhandle — Berkeley, Jefferson, and Morgan — sits at USDA zone 7a with a last frost near the first week of April (day-of-year 93-96) and roughly 207 to 213 frost-free days, a full three to four weeks ahead of the Allegheny mountain counties just west, where the last frost slips to late April and zones drop to 6a/6b. These limestone Shenandoah Valley bottomlands are WV's historic apple and peach country, so a grower here plants a Mid-Atlantic orchard-and-warm-season palette the rest of the state can't reach.
