When to Plant Oregano in Hernando County, FL

Oregano is a robust perennial herb essential to Italian and Greek cuisine. Its pungent, savory leaves intensify in flavor when dried.

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 Oregano may need afternoon shade and extra watering during peak heat.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Oregano root diseases.
