Does best on fertile soil rich in organic matter with a steady moisture supply. Winter crops need a sunny position, summer crops benefit from a little shade. Sow summer cultivars every few weeks from February (under biodegradable fleece or cloches) to the end of May. Sow winter cultivars in August and Sep, protecting the crop in cold spells.
