Growing Radishes in Wichita Falls
Wichita Falls sits in Zone 7b, with an average last frost of March 1 and first fall frost around November 22 — giving a 266-day frost-free growing season. Cool-season crops like radish benefit from Wichita Falls's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
Wichita Falls's moderate climate supports radish 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.
Wichita Falls's heavy clay soil benefits from raised beds or deep organic matter amendment before planting radish. 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.
