When to Plant Jicama in Liberty County, GA
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.
Liberty County, Georgia is in USDA Zone 8b. The average last spring frost is March 2 and the first fall frost is November 24, giving you a growing season of approximately 267 days.
At an elevation of 398 feet, Liberty County receives approximately 58.6 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 97°F, so Jicama may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — 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" — 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.
