Growing Basil in Virginia's Climate
Virginia's moderate Zone 6b climate is well-suited to basil 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 basil harvest significantly in 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 basil pests to watch for in Virginia include Aphids and Spider Mite. The first line of defense is companion planting: Tomato and Pepper 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.
