CULTURE: Brassicas prefer soil with a pH of 6–7.5 and can be grown all season in the field. Most varieties are hardy enough to grow in cool greenhouses and high tunnels during winter from late summer and early autumn sowings
DAYS TO MATURITY: From emergence after direct seeding
DIRECT SEEDING: Sow 6mm deep at 3–5 seeds/25mm, in rows at least 25mm apart from early spring into midsummer. Can be sown into late autumn if overwintering in a high tunnel or other protected structure
SUCCESSION PLANTING: For a continuous supply, sow about every 2 weeks
DISEASES & PESTS: Control flea beetles by applying fabric row cover at time of sowing and/or applying insecticides such as azadirachtin or pyrethrin. Cabbage worms and loopers can be controlled with Bacillus thuringiensis (Bt). Prevent disease with crop rotation and sanitation
HARVEST: Harvest with a knife when leaves reach desired size, about 7-15cm. Make sure to cut above the basal plate for cut-and-come-again harvests. Cut again when plants are at desired size, 5–14 days depending on variety and season
