When to Plant Jicama in Collier County, FL

Jicama is a tropical legume grown for its crisp, sweet, starchy root. It requires a very long, warm growing season but produces a refreshing, water chestnut-like tuber.

Collier County, Florida is in USDA Zone 10a. The average last spring frost is January 12 and the first fall frost is April 15, giving you a growing season of approximately 93 days.

At an elevation of 185 feet, Collier County receives approximately 61.3 inches of rainfall annually with predominantly sand soil. Summer highs average 85ยฐF, providing good warmth for Jicama during the growing season. 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.
