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.

Spacing

Single Plants: 1' 7" (50cm) each way (minimum)

Sow and Plant

Sow indoors in early spring, and set out while the soil is still cool.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

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.
