Soil
Rich, moist soil, firm with plenty of well rotted compost dug in.
Position
Full sun.
Frost tolerant
Yes.
Feeding
Mix composted manure or another high-nitrogen compost into the soil before planting. When heads begin to form, feed with a liquid plant food.
Companions
Oregano, Tomato, Celery, Dill, Sage and Mint.
Spacing
Single Plants: 1′ 7″ (50cm) each way (minimum)
Rows: 1′ 5″ (45cm) with 1′ 11″ (60cm) row gap (minimum)
Sow and Plant
Sow indoors in early spring, and set out while the soil is still cool.
Notes
Cabbageworms are small green larvae of the cabbage white butterfly. You can use row covers to keep them from eating plants. Bend over a few leaves if required so that the cauliflower head is kept shaded while it is forming.
Harvesting
Harvest when the head has fully developed, but before the curd becomes loose, with a “ricey” appearance.
Troubleshooting
When plants are stressed by cold or drought, they may refuse to make heads.
