When to Plant Garlic in Glades County, FL

Garlic is a pungent allium planted in fall and harvested the following summer. Hardneck varieties produce edible flower stalks (scapes) and are more cold-hardy.

Glades County, Florida is in USDA Zone 9b. The average last spring frost is February 1 and the first fall frost is December 19, giving you a growing season of approximately 321 days.

At an elevation of 434 feet, Glades County receives approximately 54.3 inches of rainfall annually with predominantly sand soil. Summer highs average 101ยฐF, so Garlic may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Garlic will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Garlic root diseases.
