Sowing
Clemson gives 5 to 7 weeks from sowing to transplanting for brassicas, so sow indoors in spring, or in a seedbed outdoors.
Plant out into firm soil, with the stem set deep.
Tips
- Net against birds (RHS).
- Stake tall plants in exposed gardens.
Always check the packet for your variety, and see the step-by-step guide for the basics.
