How to Grow

Cultivation

Start in seed trays or a seed bed in early spring and transplant, or sow direct after frosts. Grow in firm, fertile soil in an open, sunny spot. Where possible, avoid growing brassicas in the same soil year on year, to prevent the build up of soil-borne diseases. See cabbage cultivation for more detailed advice

Propagation

Propagate by seed. See sowing vegetable seeds

Pruning

No pruning required

Diseases

May be susceptible to club root, particularly in acidic soil
