Dates above assume Zone 7b, the most common zone in South Carolina. Gardeners in cooler Columbia (Zone 7b) plant 1–2 weeks later; warmer Charleston (Zone 9a) can plant 1–2 weeks earlier.
⚠ Plant peas 4–6 weeks before last frost — one of the first vegetables of spring. Tolerate light frost. Also plant in late summer for a fall harvest.
Growing Peas in South Carolina's Climate
South Carolina's moderate Zone 7b climate is well-suited to pea 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 pea harvest significantly in South Carolina. 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 pea pests to watch for in South Carolina include Pea Aphid and Powdery Mildew. The first line of defense is companion planting: Carrot and Radish 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.
