It creates decay
Large internodal cuts are difficult for the tree to defend, allowing dysfunction and decay to progress into major wood.
Proper pruning
Topping does not make a tree safer—or keep it small.
Removing the upper crown through indiscriminate heading cuts is one of the most damaging treatments commonly inflicted on mature trees.
It starves the tree
Leaves manufacture the tree’s food. Sudden severe leaf loss depletes stored energy and increases susceptibility to other problems.
It produces weak limbs
Rapid shoots arising below topping cuts are generally more weakly attached than the original branches they replace.
It increases wind exposure
Dense, upright regrowth can create a top-heavy crown that captures wind rather than solving the original structural problem.
It costs more
Fast regrowth requires repeated cutting, while decay and poor attachments often lead to eventual removal.
It will not keep the tree small
A healthy tree attempts to replace its lost leaf area quickly. Species choice—not repeated injury—determines mature size.
Better alternatives
Depending on the tree and objective, alternatives may include selective crown reduction, structural pruning, end-weight reduction, clearance pruning, phased restoration or replacement with a species better suited to the available space.
