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
A tomato planted in a West Virginia hollow fights fog all summer.
Fog settles where cold air does
West Virginia's hollows fill with more than just cold air on a still night; the same settling air often carries enough moisture to leave a thick fog sitting in the bottom well past sunrise, long after a bed on the slope above has already dried off in open morning sun. That extra stretch of wet leaves hanging on past sunrise is precisely what lets early and late blight get a foothold, which is why a tomato bed down in a hollow runs more blight-prone than the identical planting a short walk uphill, even on matching soil.
Siting a tomato bed on a south-facing slope shoulder instead trades that lingering fog for faster morning drying and more direct sun through the day, both of which cut down the hours a leaf stays wet enough to infect. Watch the lowest, oldest leaves first for dark, ring-marked spots; that bottom-up progression is what tells blight apart from a tomato plant simply running out of season, no matter which side of the hollow the bed sits on.
Thin mountain soil calls for a filled hole, not a whole amended bed
Much of West Virginia's hillside ground is thin and rocky, sometimes only a few inches of real topsoil over broken shale, which makes amending an entire bed impractical the way it would be on a deep valley floor. The more workable approach on a genuinely thin slope is to dig an oversized planting hole for each tomato, wider and deeper than the root ball needs, and fill it generously with compost, giving each plant its own pocket of good ground rather than trying to fix the whole hillside at once.
Stake or cage every plant regardless of soil depth, both to keep fruit off ground that a hard mountain rain can splash blight spores up onto, and because a shallow-rooted plant in thin soil is more prone to toppling in a slope's stronger wind exposure than one growing in a deep, sheltered valley bed.
Hornworm hides at exactly leaf height
Tomato hornworm blends into the plant almost perfectly, a caterpillar several inches long in the same green as the foliage it is eating, so most gardeners find the evidence, bare stripped stems and dark droppings scattered on the leaves underneath, well before they spot the insect responsible. Look at the height where the damage stops and start scanning the stem and nearby leaves right there; the caterpillar rarely moves far from its last meal.
If a hornworm turns up carrying small white cocoons stuck along its back, leave it exactly where it is. Those are a parasitic wasp's eggs, already killing the caterpillar from within, and the wasps that emerge will go on to hunt down the next generation of hornworms in the same bed, which does more for a hillside garden over time than picking off one caterpillar by hand.
In West Virginia: watch for
The pests that find tomatoes here.
A middle-length season, about 172 frost-free days, means tomato, slicing overlaps tomato hornworm for a stretch each summer. Check plants every week or two and treat early.
Big green caterpillars strip leaves and leave black droppings.
Organic fix: Handpick at dusk; spray Bt on the young ones.
Clusters on new growth, sticky leaves, curling tips.
Organic fix: Blast with water, then insecticidal soap or neem.
Dark spots with concentric rings, starting on the lowest, oldest leaves.
Organic fix: Remove affected leaves, mulch to stop soil splash, space for airflow.
Greasy, water-soaked blotches in cool, wet spells. No rings, and not bottom-up.
Organic fix: Pull infected plants fast, keep leaves dry, use neem as a preventive.
Septoria leaf spot
Many small tan spots with dark brown edges, low leaves first, no rings inside.
Organic fix: Strip the lowest leaves, mulch against soil splash, stake for airflow.
Your season math: West Virginia gives tomatoes about 172 frost-free days, and it needs roughly 73 days to a first harvest. It's a one-planting crop, so time that single sowing well.
