How to Grow

Lettuce is a sun-loving cool weather crop that grows best in organic, well drained soil. Sow as soon as the soil can be worked in the spring, then every two weeks thereafter to ensure a continuous supply. Sow about 3mm (1/8in) deep in rows 45cm (18in) apart. An even supply of moisture during the entire growth period is imperative for success. Harvest leaf lettuce by either pulling the entire plant or by cutting leaves from the main stem at least 2.5cm (1in) above the base – this will allow the plant to sprout new leaves. Once lettuce bolts (starts to produce a rapidly growing flower stem) leaves become bitter.
