When to Plant Borage in DeSoto County, FL

Borage is a self-seeding annual herb with star-shaped blue flowers that attract pollinators. Its leaves have a cucumber-like flavor and the flowers are edible.

DeSoto County, Florida is in USDA Zone 9b. The average last spring frost is February 1 and the first fall frost is December 20, giving you a growing season of approximately 322 days.

At an elevation of 214 feet, DeSoto County receives approximately 53.6 inches of rainfall annually with predominantly sand soil. Summer highs average 97ยฐF, so Borage may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Borage will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Borage root diseases.

Borage 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.

Borage needs ~1,251 GDD — county provides 7,348 GDD Excellent fit
