Growing Brussels Sprouts in West Virginia's Climate
West Virginia's moderate Zone 6b climate is well-suited to brussels sprout with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your brussels sprout harvest significantly in West Virginia. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common brussels sprout pests to watch for in West Virginia include Cabbage Worm and Aphid. The first line of defense is companion planting: Onion and Celery planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.
