Should you cut the bottom leaves off tomato plants?
As the plants grow, revisit them regularly and keep the bottom 6 to 12 inches bared. Trim away these lower leaves and stems while they’re small, rather than letting them grow. This conserves the plant’s resources, and a smaller pruning wound creates less opportunity for disease to enter.
