A wonderful head lettuce from the UK. It doesn’t take much work to grow lettuce from seeds. Lettuce seeds are often quite small and only require a planting depth of ¼ to ½ inch deep. Growing lettuce in rows gives your garden a traditional look. Consider alternating rows of green and red lettuce for a whimsical touch.
How far apart to plant lettuce depends on the type of lettuce you’re planting. When sowing seeds directly into the soil, you should plant approximately 10 seeds per foot. Space your rows 12 to 18 inches apart. Thin leaf lettuce seedlings to 4 inches apart. Romaine and butterhead lettuce seedlings require 6 to 8 inches between each plant. Removed seedlings can be transplanted or eaten as delicious, tender microgreens.
Head lettuce is usually grown from seeds started indoors during warm weather for a fall garden. Transplant head lettuce in rows 12 to 18 inches apart with 10 to 12 inches between each plant.
You don’t need lettuce to develop deep roots. In fact, you want to encourage leaf growth over rooting. Lettuce watering should be light, frequent and consistent. The goal is to simply keep the soil moist. Avoid watering too often – overwatering leads to root rot, disease and stunted growth.
