When to Plant Mache in Gilchrist County, FL

Gilchrist County, Florida is in USDA Zone 9a. The average last spring frost is March 3 and the first fall frost is November 27, giving you a growing season of approximately 269 days.

At an elevation of 236 feet, Gilchrist County receives approximately 53.5 inches of rainfall annually with predominantly sand soil. Summer highs average 102ยฐF, so Mache may need afternoon shade and extra watering during peak heat.

Mache 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.

Mache needs ~1,325 GDD — county provides 7,128 GDD Excellent fit
