Growing Instructions:
Direct sow lettuce seeds in early spring or late summer, depending on your climate. Choose a location that receives partial shade in hotter climates and full sun in cooler climates. Sow seeds 1cm (½”) deep, spaced 2.5-5cm (1-2”) apart in rows spaced 30-45cm (12-18”) apart. To promote germination, keep the soil consistently moist and cool. The seeds should sprout in 7-14 days. Thin seedlings to 15-25cm (6-10”) apart when they are 5-7cm (2-3”) tall.
Lettuce prefers well-drained soil that is rich in organic matter. The soil pH should be between 6.0 and 7.0. Fertilize with a balanced fertilizer every 4-6 weeks during the growing season. Harvest lettuce leaves when they are young and tender. Cut the entire plant or pick individual leaves as needed. Lettuce is a cool-season crop and can bolt (go to seed) in hot weather. Providing shade or planting in a cooler location can help extend the growing season. Soil Conditions: Well-drained soil that is rich in organic matter.
