Growing Peas in Broken Arrow
Broken Arrow sits in Zone 7a, with an average last frost of March 15 and first fall frost around November 15 — giving a 245-day frost-free growing season. Cool-season crops like pea benefit from Broken Arrow's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
Broken Arrow's moderate climate supports pea on the standard transplant calendar with minimal special accommodation. Succession planting — sowing fresh seeds or setting new transplants every 2–3 weeks through spring — stretches the harvest window and gives you a backup crop if pests hit the first planting.
Broken Arrow's heavy clay soil benefits from raised beds or deep organic matter amendment before planting pea. Clay retains moisture well but compacts easily — add 3 to 4 inches of compost and work it in to 12 inches before planting. Consistent watering (1 inches per week) is especially important in clay soil, which can crack and pull away from roots during dry spells; mulch around plants to stabilize moisture.
