• How to Grow Lettuce
Lettuce grows best in rich, fertile soil that is well drained but retains moisture. It grows well in full sun but can also tolerate little shade in hot weather. If left unattended, Lettuce will become bitter and bolt to seed, hence be sure to water it regularly, mulch and fertilize well.
• Growing with Lettuce Seeds
Sow the seeds in clumps 20-30 cm i.e. 8-12 inches apart on the well-worked soil. Or use seedlings to save four weeks of growing time. When the seedlings are about 4cms high, thin all but the strongest seedling. Leaf Lettuce self-seed, but if you are looking for a continuous supply, then sow every four weeks.
