Eggplant is a heat-loving solanaceous crop that produces glossy fruits in purple, white, or striped varieties. It requires long, warm growing seasons for best production.

Glades County, Florida is in USDA Zone 10a. The average last spring frost is February 1 and the first fall frost is December 19, giving you a growing season of approximately 321 days.

At an elevation of 434 feet, Glades County receives approximately 54.3 inches of rainfall annually with predominantly sand soil. Summer highs average 101°F, so Eggplant may need afternoon shade and extra watering during peak heat.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Eggplant root diseases.

Eggplant 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" — every day above 50°F 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.

Eggplant needs ~1,931 GDD — county provides 8,291 GDD Excellent fit
