When to Plant Marigolds in Brevard 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.

Brevard County, Florida is in USDA Zone 10a. The average last spring frost is January 19 and the first fall frost is December 20, giving you a growing season of approximately 335 days.

At an elevation of 491 feet, Brevard County receives approximately 52.7 inches of rainfall annually with predominantly sand soil. Summer highs average 104°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.
