Sowing – Sowing Time March to June. Sow seeds thinly, 1cm (1/2in) deep in drills 23cm (9in) apart in well-drained, fertile soil, which has been raked to a fine tilth and contains plenty of well-rotted compost or organic matter. It will also be beneficial to rake in 3oz/sq yard of any balanced fertiliser.

Growing – Transplant when seedlings have 5-6 leaves, spacing 38cm (15in) apart each way. Water ground regularly, especially in dry periods. Hoe between plants occasionally, and give a liquid feed as heads begin to develop.

Harvest – June to October
