Lettuces are grown for their leaves, and like many similar vegetables, the best results and the tastiest leaves are achieved by never letting the plants dry out.

Lettuce is a relatively fast growing crop that can be tucked into corners and under tall plants like sweetcorn and brussels sprouts. Sow a few seeds every two to three weeks from spring through summer for a continuous supply and to avoid having dozens of lettuces all maturing at the same time.
