7 - How to grow
Cultivation
Grow in fertile soil in full sun and maintain a steady water supply. Space closely where smaller heads are wanted, or allow more room for larger curds. The compact habit also suits containers with sufficient depth, fertility and consistent watering.
Propagation
Propagate by seed, sown outdoors or started indoors.
Pruning
No pruning is required.
Pests
Plants may be damaged by birds and caterpillars. Net young crops securely and inspect leaf undersides regularly.
Diseases
Plants may be susceptible to club root. Use clean transplants, avoid moving contaminated soil and rotate brassicas where possible.
