When to Plant Romanesco in Orange County, TX
Romanesco is a stunning brassica with a lime-green head composed of fractal-patterned spiraling florets. It has a nuttier, milder flavor than cauliflower.
Orange County, Texas is in USDA Zone 9b. The average last spring frost is February 12 and the first fall frost is December 11, giving you a growing season of approximately 302 days.
At an elevation of 231 feet, Orange County receives approximately 63.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98°F, so Romanesco may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Romanesco will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Romanesco root diseases.
