Pick when young and add raw to salads, and as long as the leaves are picked reguarly and young they will remain tender and of mild flavour. The water on the leaves after a thorough washing is sufficient for cooking them. Sow every few weeks from March onwards for a regular supply. Sow the seeds thinly 2cm deep in rows 30cm apart, thin as soon as possible to leave 15cm between plants. Water regularly. Winter varieties should be sown during August and September for spring harvesting.
