Looseleaf lettuce is the fastest growing type and can be grown anywhere as long as you have composted soil. Lettuce grows best if planted indoors and transplanted outdoors in early spring. Lettuce will better tolerate heat if plants are well thinned and air can circulate around them. Culture: Plant in weed free soil soon as it can be worked in the spring. Sow again when the weather cools in late summer or fall. Plant in rows or broadcast in a section of the garden. Water regularly and fertilize when 3″ (7.5 cm) tall. Protect from slugs and snails. Harvesting: Harvest with scissors. Snip the leaves about ½”–1″ (1.5–2.5 cm) above the soil line when 4″–6″ (10–15 cm) tall. Many varieties are cut-and-come again, so will resprout and grow again. Or just cut above the surface and reseed. Nutrition: Rich in fiber and potassium, with moderate amount of vitamin A.
