Hendry County, Florida is in USDA Zone 10a. The average last spring frost is January 14 and the first fall frost is April 15, giving you a growing season of approximately 91 days.

Corn 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.

Corn needs ~1,340 GDD — county provides 6,113 GDD Excellent fit
