To promote good germination for your Lettuce, prepare the sowing bed by tilling well before sowing the seeds. The soil on your seedbed must be loose and well-draining and not too soggy. Directly sowing the seeds in the soil about half an inch deep and cover them with ¼ to ½ inches of soil. You also plant chives or garlic as companion plants for romaine lettuce to keep the pests at bay. Make sure that the soil remains moist but well-drained or root rot & bolting may damage your plants.Aphids are the most common pests that are likely to damage the lettuce. They can suck the water and nutrients away from the lettuce leaves and cause them to wilt. This can also cause the plant to have molding issues. Organic neem spray or oil is your best bet against aphids. Moreover snails, slugs and caterpillars can also damage your lettuce plant and timely removing them from the plant is the most effective way to protect your plant.SOIL Ensure fertile, well-drained, moist soil for lettuce with a pH between 6.0 and 7.0. The romaine lettuce grows best in loose soil. Lettuce is sensitive to acidic soil so maintain a pH above 6.SPOT Lettuce grows best in full sun but can also tolerate partial shade as well.TEMPERATURE Ideal soil temperature for germination: 10-22°C (50-72°F). If the weather is too hot, the plant may go straight to seeding instead of producing optimum leaves.WATERING Water the lettuce plant lightly and frequently to keep the soil moist to promote leaf growth instead of root growth.
