Cauliflower

Cauliflower is a cool-season brassica that produces dense white, purple, or green heads called curds. It is more finicky than broccoli but rewards with a mild, nutty flavor.

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 Cauliflower may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Cauliflower will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Cauliflower root diseases.
