Moore County, Texas is in USDA Zone 7a. The average last spring frost is April 16 and the first fall frost is October 22, giving you a growing season of approximately 189 days.

At an elevation of 1,940 feet, Moore County receives approximately 58.2 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95ยฐF, so Radish may need afternoon shade and extra watering during peak heat.

Radish Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" โ€” every day above 50ยฐF deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Radish needs ~606 GDD — county provides 4,016 GDD Excellent fit
