You can wrap them in a wet wipe and germinate them at 15-20°C.
2. Daily management: During the seedling stage of round lettuce, the soil needs to be kept moist. Do not let the soil dry out, and maintain the soil's water permeability. When round lettuce grows to 5-6 true leaves, it needs to be transplanted. First water thoroughly, then transplant it together with the roots into a prepared container. About 1 week after transplanting, it needs fertilizing. Then apply decomposed organic fertilizer once each at two weeks and four weeks after transplanting. When watering round lettuce, pay attention to the problem of high temperature and drought, and water less at night. The principle for watering round lettuce is to water little but often, but avoid waterlogging.
3. Harvesting: Stop fertilizing 2 weeks before harvesting, and simply pull the round lettuce up by the roots.
