Site, Soil and Preparation
Grow lettuces in full sun in moisture-retentive soil. Early and late sowings may need protection against cold, using cloches, plastic tunnels or horticultural fleece. Prepare the ground for your Lettuce seed sowing, removing weeds, fork in organic matter or well-rotted manure. Consolidating and raking a nice fine seedbed.
Indoor Sowing
Alternatively, start lettuce off in trays of individual cells or a cell propagator. Always use a decent peat-free compost.
Outdoor Sowing
Sow seeds thinly, 13mm (1/2in) deep, in rows 30cm (1ft) apart. Sow a short row every fortnight to ensure continuity of cropping.
Thinning
Thin seedlings as soon as the first true leaves appear and continue until the plants are 30cm (1ft) apart. The seedlings you thin out can be added to salads.
Transplanting
Indoor sown lettuce seed can be transplanted once large enough to handle.
Care
Watering regularly particularly in dry conditions, a regular liquid feed will be beneficial and always check for the dreaded slugs and snails.
Harvest
You can harvest lettuces from late spring through to winter, if sown regularly using suitable seasonal varieties. Whole lettuces are ready to harvest when a firm heart has formed - cut through the stem at the base.
