When to plant green beans in West Virginia.
Sow between Apr 28 to Jun 18 in a typical year, keyed to West Virginia's median last frost around Apr 28. A second, fall sowing fits Jul 3 to Aug 5. Dates below are state medians; your ZIP code shifts them by days to weeks.

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 hillside bean row beats the calendar every spring.
Aspect decides when the soil is actually ready
Green beans will not germinate reliably in cold ground, and in West Virginia's mountain terrain, ground temperature has as much to do with which way a garden faces as it does with the date on the calendar. A south-facing slope catches more direct spring sun and warms noticeably faster than a shaded hollow bottom or a north-facing hillside a short distance away, which means two West Virginia gardens at roughly the same elevation can be ready for beans weeks apart depending on which way they face.
The gardener working a valley-bottom or north-facing plot does better waiting for the soil itself to prove it is ready rather than following a neighbor's slope-sited garden. A simple check works either way: press a finger into the top couple of inches, and soil that feels cool and damp rather than warming through the day is still telling a bean seed to sit and rot instead of sprout.
The same cold air that delays planting also brings frost pockets
Beans are killed outright by frost, not just slowed by it, and a hollow-bottom garden that finally warms up enough to plant in spring can still catch a late frost that a slope-shoulder garden nearby escapes entirely, because cold air continues draining downhill and pooling at the bottom on any clear, calm night through late spring. A gardener working bottomland should treat the average last-frost date as optimistic rather than reliable and hold off a little longer than that date suggests, or keep row cover on hand for a night that turns colder than forecast.
A slope-sited bed carries the opposite risk in fall: it holds warmth a little later into the season than a hollow bottom, which can mean a few extra weeks of picking before the first real frost ends the planting. That gap between two gardens a short walk apart is exactly why the state's hillside-gardening tradition treats siting as seriously as variety choice.
Mexican bean beetle and thin mountain ground
Mexican bean beetle looks almost exactly like a large, coppery ladybug at first glance, which fools plenty of gardeners into leaving it alone until the yellow, spiny larvae underneath the leaves have already lace-holed a full row. Checking the undersides of a handful of plants weekly and crushing both the adults and the bright yellow egg clusters found there keeps a light infestation from building into a real problem.
West Virginia's thin, rocky mountain soil holds nutrients and moisture poorly compared to a deep valley-floor bed, and beans grown there benefit from 2 inches of compost worked into the row at planting more than beans grown in richer bottomland do. That same thin soil drains fast after a hard mountain rain, which is one advantage over a heavier bottomland bed that can sit wet and encourage rust and powdery mildew on the leaves.
In West Virginia: watch for
The pests that find green beans here.
A middle-length season, about 172 frost-free days, means bush bean overlaps mexican bean beetle for a stretch each summer. Check plants every week or two and treat early.
Coppery ladybug-like beetles; leaves skeletonized to lace.
Organic fix: Handpick adults and yellow egg clusters; neem.
Orange or white spots on leaves late in the season.
Organic fix: Water at the base, space plants, spray neem.
Anthracnose
Sunken dark-red cankers on the pods, and leaf veins turning brick-red to black underneath.
Organic fix: Start with certified seed, water at the base, and stay out of the patch while the leaves are wet.
Your season math: West Virginia gives green beans about 172 frost-free days, and it needs roughly 55 days to a first harvest. That fits about 12 re-sown rounds across the season, so you can keep it coming instead of picking once.
