Step 2: How to trim vegetables
When the lettuce has grown 2 pairs of leaves, if the density of seedlings is high, you can pick the vegetables to eat gradually or move them to another pot for better growth. Before pruning the vegetables, add nutrients to the soil such as organic powder, coconut fiber, and compost to help the lettuce take root quickly. This is one of the ways to grow purple lettuce for high yield and vegetables that grow well with large, wide leaves.
