Use as you would spring greens, harvesting from the bottom of the plant to encourage more growth at the top. In trials, plants suffered less pests than cabbage or kales, plus they are more disease resistant.Sow thinly direct into a finely raked seedbed at a depth of 13mm (½in).Transplant with a trowel or dibber when large enough to handle allowing 45cm (18in) between plants each way. Grows best in well-cultivated soil liberally manured the previous autumn. If the weather is dry, water in well when transplanting. Alternatively sow in modules and plant out after all risk of frost has passed.
