When to Plant Marigolds in Madison County, FL

Marigolds (Tagetes patula) are warm-season annuals beloved for their cheerful orange, yellow, and red blooms — and for their well-documented ability to repel pest nematodes in vegetable beds. Easy from seed, drought-tolerant once established, and bloom from early summer until the first hard frost.

Madison County, Florida is in USDA Zone 9a. The average last spring frost is March 5 and the first fall frost is November 25, giving you a growing season of approximately 265 days.

At an elevation of 434 feet, Madison County receives approximately 61.2 inches of rainfall annually with predominantly sand soil. Summer highs average 95°F, so Marigolds may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Marigolds will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Marigolds root diseases.
