Liberty County, Texas is in USDA Zone 8b. The average last spring frost is February 14 and the first fall frost is December 1, giving you a growing season of approximately 290 days.

At an elevation of 141 feet, Liberty County receives approximately 60.7 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97ยฐF, so Daikon may need afternoon shade and extra watering during peak heat.

Daikon 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.

Daikon needs ~1,365 GDD — county provides 6,620 GDD Excellent fit
