Introduction
Cauliflower Romanesco (Brassica oleracea) is a visually stunning variety with lime-green, spiraling fractal heads. It is a moderate cool-season crop that requires consistent care and performs best in Florida's fall and spring seasons.
Growing conditions
- Light: Full sun, 6+ hours daily.
- Water: Moderate to high; keep soil consistently moist.
- Soil: Rich, well-draining soil with good organic matter.
- Fertilizer: Nitrogen-rich fertilizer every 3 to 4 weeks.
- Season: Cool-season crop; best in fall and spring in Florida.
Planting tips
Start seeds indoors 4 to 6 weeks before transplanting. Space plants 18 to 24 inches apart. Romanesco is sensitive to temperature fluctuations — consistent cool weather produces the best heads. Blanch heads by tying outer leaves over them to protect color and flavor.
Troubleshooting
Loose or ricey heads
Heat or temperature stress. Plant in cool seasons and maintain consistent moisture.
Yellow leaves
Nitrogen deficiency or overwatering. Feed regularly and check drainage.
Pests
Cabbage worms and aphids. Use row covers and treat with organic insecticidal soap.
Pet safety
Cauliflower Romanesco is non-toxic to pets.
