Sow 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). May need staking. See broccoli cultivation for more detailed advice
Propagate by seed. See sowing vegetable seeds or sowing seeds indoors for further advice
No pruning required
May be susceptible to flea beetle, caterpillars, pigeons and snails, although once plants are established, this damage isn't usually severe. May also be susceptible to cabbage root fly and mealy cabbage aphid
May be susceptible to brassica downy mildew and brassica white blister. In areas where brassicas have been grown before, club root can build up in the soil
