Okra is a heat-loving tropical plant that produces edible seed pods. It thrives in hot summers and produces beautiful hibiscus-like flowers before setting pods.

Highlands County, Florida is in USDA Zone 9b. The average last spring frost is January 29 and the first fall frost is December 20, giving you a growing season of approximately 325 days.

At an elevation of 111 feet, Highlands County receives approximately 57.6 inches of rainfall annually with predominantly sand soil. Summer highs average 95°F, so Okra may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Okra will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Okra root diseases.

Okra 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.

Okra needs ~1,222 GDD — county provides 6,927 GDD Excellent fit
