When to Plant Garlic in Hernando 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.

Hernando County, Florida is in USDA Zone 9a. The average last spring frost is January 25 and the first fall frost is December 16, giving you a growing season of approximately 325 days.

At an elevation of 245 feet, Hernando County receives approximately 51.5 inches of rainfall annually with predominantly sand soil. Summer highs average 99ยฐF, 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.
