Growing Spinach in Alabama's Climate
Alabama's moderate Zone 7b climate is well-suited to spinach 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 spinach harvest significantly in Alabama. 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 spinach pests to watch for in Alabama include Leaf Miner and Aphid. The first line of defense is companion planting: Pea and Strawberry 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.
