how to cut lettuce

2. Cut off the outer leaves of the plants with a small pair of garden shears to harvest just a few leaves. Remove the leaves at the base, leaving the inner leaves to grow on and continue producing. Trim back the entire plant when it reaches 3 to 6 inches high, or approximately every 10 days.
