Ohio gardeners in Zone 6a have a 31-week growing season for pea (March 30 to November 1). Ohio's spring and fall windows both work well for pea — some gardeners plant both successions for a long harvest. This guide gives exact dates for Ohio based on your local frost calendar.

Pea Planting Dates for Ohio

Dates above assume Zone 6a, the most common zone in Ohio. Gardeners in cooler Cleveland (Zone 5b) plant 1–2 weeks later; warmer Cincinnati (Zone 6a) 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 Ohio's Climate

Ohio's moderate Zone 6a 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 Ohio. 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 Ohio 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.

Pea Growing Tips for Ohio Gardeners

  • Soak pea seeds overnight before planting to speed germination in cool soil.
  • Install a 4–6 foot trellis at planting time — peas climb from day one and produce more per square foot when supported.
  • Ohio's moderate climate supports succession planting — sow new transplants or seeds every 3 weeks during spring to extend the harvest window into fall.
  • Sow every 2 weeks through early spring for a continuous 6-week harvest window.

Companion Planting for Peas in Ohio

In Ohio's moderate climate, planting pea with Carrot and Radish helps deter pests and improve soil. Avoid planting near Onion and Garlic, which inhibit pea growth through root chemistry or shared pest pressure. See the full pea companion planting guide for the complete list.
