When to Plant Jicama in Osceola County, FL

Osceola County, Florida is in USDA Zone 9b. The average last spring frost is January 22 and the first fall frost is December 20, giving you a growing season of approximately 332 days.

At an elevation of 352 feet, Osceola County receives approximately 58.7 inches of rainfall annually with predominantly sand soil. Summer highs average 102ยฐF, so Jicama may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Jicama will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Jicama root diseases.

Jicama 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.

Jicama needs ~3,975 GDD — county provides 8,824 GDD Excellent fit
