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

Notes
Surround stem with a 10cm (4 inch) mat with a slit cut into it for the stem to prevent cabbage root fly from destroying the roots. Use fine mesh or fleece over the summer to prevent butterflies laying eggs on the underside of leaves - caterpillars can destroy these plants. Protect against birds which can damage the young seedlings.
|
Harvesting
Harvest from mid summer onwards 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.
