There are 4 basic types of lettuce. Crisp (which is the most difficult to grow), Butter lettuce (loose heads with green outer leaves and yellow inner leaves), Loose leaf (form rosettes rather than heads) and Romaine (grows erect with green outer leaves and white inner leaves). Lettuce grows well in loose well drained fertile soil. Plant in partial shade if growing in hot summer weather. Plant lettuce in rows 8-12 inches apart in open ground just after last frost. Cover seeds lightly with soil. Water regularly but feed lightly. Lettuce can be started indoors and transplanted outside when grown in short summer climates. Lettuce can also be grown in containers 8 inches wide and 6-8 inches deep.
Harvesting Lettuce and Salad Greens
Harvest loose leaf lettuce as needed. Head lettuce should be harvested when the heads have formed and are firm when squeezed. Pick whole heads of both head and leaf lettuce before the seed stalks breakthrough.
Pests in Lettuce and Salad Greens
- Aphids are present when foliage curls, puckers and turns yellow. Vigorously spray infected leaves with water.
- Sails and slugs are present when leaves have large ragged holes. The best method for ridding snails and slugs is to pick them out of your garden each morning.
