Safety around large trees is important. Cutting heavy branches seems to make sense. But in the long run, the trees become even more hazardous to people and property when trees are topped.
It would seem removing the weight off the top of a tree, it would make the tree safer.
Not so.
Actually, by topping a tree,
you are creating weak crotch angles
that can lead to dead tops
and broken branches.
Also, these large open cuts will almost never close up leading to trunk rot and insect infestation.
The following fact sheet highlights proper pruning and wound care:
When trees are cut way back like these crabapples,
multiple suckers will result.
Or in this case, a Honeylocust.
In a woodlot, trees tend to shade each other’s bottom branches,
which naturally leads to better growth structure and healthier trees.
Tree pruning is important to the health of trees and the landscape.
