Sow and Plant

Sow either direct into soil or in pots to plant out later if clubroot disease is a problem in your soil.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.


Use fine mesh or exclusion netting over the warmer months to prevent butterflies laying eggs on the underside of leaves - caterpillars can destroy these plants. Protect against birds which can damage the young seedlings.


Harvest by cutting off the large central head first before it starts to flower. Smaller side shoots should then be produced for harvesting a few weeks later.
