Sow thinly into finely raked, warm, moist soil at a depth of 13mm (½") in blocks or rows, sprinkling a few seeds every 30cm (12"). (Germination 6-12 days.) Remove surplus seedlings to leave the strongest at each station. Use the 'thinnings' as baby leaves. Lettuce grows best in well-cultivated soil in a sunny position. Water freely during dry weather. Early sowings may be started undercover and planted out.
