Sow seed outdoors in fertile but firm, soil that isn't too acidic. Or 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). Support plants in late summer with a sturdy bamboo cane to protect from wind. For more advice see brussels-sprout cultivation
Propagate by seed. See sowing vegetable seeds or sowing seeds indoors
No pruning required
May be susceptible to flea beetle, cabbage root fly, caterpillars, pigeons and snails, although once plants are established, this damage isn't usually severe. Heavy infestations of mealy cabbage aphid may also spoil the harvest
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
