How to grow lettuce
Regularly sow lettuce seed 0.5cm deep in pots or rows. Thin or transplant seedings to 15-30cm apart. Use cloches or grow indoors/under cover to extend the growing season.
Water in dry weather to avoid tough and bitter leaves and during the morning to discourage disease. Protect your lettuce from slugs and snails and if you're growing lettuce in a greenhouse or under a cloche, keep it well ventilated.
Harvesting and using lettuce
Pick individual leaves of 'loose leaf' lettuce as needed. Cut 'hearting' varieties when the central leaves are fairly firm. Regularly cut seedling leaves.
