West Virginia spans more than one climate: Zone 6 is the most common zone, but the state runs 6a to 7a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
West Virginia growing notes
West Virginia's sour mountain soil is a genuine potato advantage.
Acidic ground suppresses a disease that plagues sweeter soil
West Virginia's naturally acidic mountain soil is doing a potato grower a favor most never notice: scab, the rough corky patches that blemish a tuber's skin without touching the eating quality underneath, needs a sweeter pH than this ground usually offers, so the disease that plagues a limestone-valley potato bed elsewhere rarely gets a foothold here. Gardeners working the state's rarer sweeter, limestone-derived pockets are the ones who actually need to manage pH down for potatoes; everyone else can put that effort into drainage instead, which matters far more on a slope.
Acidic ground has one catch worth knowing, though: hollow heart, a dark cavity inside a tuber that stays invisible until you slice it open, shows up when a hillside planting gets checked by a dry stretch and then surges once a hard mountain rain returns. Watering evenly through the weeks the tubers are bulking prevents it more reliably than any soil amendment does, and setting seed pieces a little closer in the row keeps individual tubers from swelling fast enough to split their own centers open.
Terracing a slope instead of fighting it
A hillside potato bed sheds a hard mountain rain fast, which cuts down on the standing water that rots seed pieces before they sprout, but that same slope lets soil wash right off the row if it is not managed. Running potato rows across the slope rather than straight down it, and hilling generously around the stems as the plants grow, both slow that runoff and keep developing tubers covered before West Virginia's summer sun has a chance to turn any exposed shoulder green within a matter of days.
Cut seed pieces so every piece keeps a solid eye, then spread them out on a tray somewhere cool and ventilated, checking daily rather than by the clock, until the cut face has sealed into a dry, leathery skin rather than staying glossy and wet-looking. A raw cut buried straight into a damp hillside row rots at a much higher rate than a healed one does, and on a slope, where water draining off the row above tends to linger longest at the bottom, that healing step matters even more than it would on flat ground.
A beetle that overwinters right in the row
The adult Colorado potato beetle rides out winter tucked into the soil of the very row it fed on the summer before, and it takes surprisingly little to bring it back out, just a handful of genuinely warm days is enough to send it digging upward toward whatever potato foliage has emerged first. West Virginia's mountain season supports two full generations of it before frost, so a single missed scouting week in early summer can let the second wave build unnoticed.
Flip a leaf on ten plants once a week and count what is there: two or more larvae per plant on average is the signal to act, and acting usually just means crushing the egg clusters under a thumb and dropping the adults into a cup of soapy water before they can drop off and hide in the mulch. Moving next year's potato bed to ground that has not grown a potato, tomato, or pepper in three years still pays off even though the adult beetle can fly: forcing it to search a hillside instead of simply walking over from last year's row cuts down how many ever find the new planting.
In West Virginia: watch for
The pests that find potatoes here.
A middle-length season, about 172 frost-free days, means potato overlaps colorado potato beetle for a stretch each summer. Check plants every week or two and treat early.
Striped beetles and orange grubs eating the leaves.
Organic fix: Handpick adults, crush the orange egg clusters, dust with diatomaceous earth.
Dark greasy blotches after cool, wet spells.
Organic fix: Pull infected plants fast, keep leaves dry, use neem as a preventive.
Common scab
Rough, corky patches on the skin, raised on some tubers and sunk into pits on others.
Organic fix: Keep the bed evenly moist through the weeks right after tubers set, rotate away from potatoes, and pick a scab-resistant variety next time.
Your season math: West Virginia gives potatoes about 172 frost-free days, and it needs roughly 90 days to a first harvest. It's a one-planting crop, so time that single sowing well.
