When to Plant Thyme in Ona, FL

Thyme

Thyme is a low-growing perennial herb with tiny, aromatic leaves and a warm, earthy flavor. It is one of the most versatile culinary and medicinal herbs.

Ona, Florida is in USDA Zone 9b. The average last spring frost is January 27 and the first fall frost is December 20, giving you a growing season of approximately 327 days.

At an elevation of 374 feet, Hardee County receives approximately 59.8 inches of rainfall annually with predominantly sand soil. Summer highs average 102°F, so Thyme may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Thyme will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Thyme root diseases.
