How to Prune Tomato Plants
Indeterminate tomatoes benefit from selective sucker removal and good airflow. Determinate bush tomatoes set much of their crop at once and should not be heavily pruned. In both types, remove damaged leaves and foliage touching the soil.

Confirm determinate or indeterminate
Check the label or variety. Keep pruning light on determinate tomatoes because removing branches can remove much of the future crop.
Remove unhealthy lower leaves
Cut leaves that touch soil or show disease, working upward gradually rather than stripping the stem.
Pinch selected suckers
On indeterminate plants, pinch small suckers from the leaf axils while preserving the main stem and enough foliage to shade fruit.
Tie in the remaining stems
Support stems loosely after pruning so wind does not stress the new structure.
Do not remove all suckers at once
Do not expose ripening fruit suddenly in very hot sun
Avoid pruning wet plants because disease spreads more easily
Water at soil level
Disinfect tools after diseased plants
Check ties as stems thicken
