Lettuce – Rubin – Lactuca sativa
Soil & Water: Lettuce likes full sun except in hot summer climates where it prefers some shade, especially in the afternoon. Add plenty of compost to the soil to encourage rapid growth. Water evenly and moderately to prevent bitterness.
Planting & Growing: Start seeds indoors 4 weeks before transplanting outside, or sow seed directly as soon as soil can be worked. Make successive plantings every 10-14 days for a continuous harvest. In mild climates, lettuce can be sown from spring through fall.
Harvesting & Storage: Begin harvesting outer leaves as soon as they are large enough and continue until a central stalk begins to form, which signals the end of the harvest period. You can also harvest the entire plant when it’s mature but still young and crisp.
