How to grow
Cultivation
Grow in fertile, moist but well drained soil, in full sun. Sow early under cloches in February or start in modules indoors and transplant out in Spring, early Summer. See Vegetable CultivationSow seed outdoors in deep, fertile but firm, soil that isn't too acidic. If space is limited, start the seeds in modules or seedtrays and plant outside when big enough to handle easily (about 5 or 6 leaves). Watering through the summer months is very important. For more advice see vegetable cultivation
Propagation
Propagate by seed. See sowing vegetable seeds

Pests
May be susceptible to flea beetle which can prevent seedlings from thriving and attacked by caterpillars when eggs laid by butterflies, hatch and feed. It is very popular food for pigeons which only netting can prevent. It is also eaten by snails, although once plants are established, this damage isn't usually severe. The cabbage root fly can cause failure to thrive and a heavy infestation of mealy cabbage aphid can spoil the harvest
Diseases
May be susceptible to club root, powdery mildew, black rot, grey mould, leaf spot
