TREE TOPPING
Topping is the removal of vertical leader stems on large trees and usually made between nodes or at internodes. Tipping is the internodal cut on large lateral branches.
No matter how we make the cuts tipping and topping cause serious injury to the tree. A very big misconception is that if we top the tree it will be safer. Topping greatly increases the tree of being a risk of a hazard. Topping is the biggest money wasting practice in the world. It also is illegal in some counties in some states. It is a crime against nature. Topping is a worldwide tree mutilation practice. The main reason is that people do not understand how trees function.

Some effected parts of the system are the non-woody roots, the woody
roots, and many microorganisms within the soil. The food for the woody
and non-woody roots come from the top. Many microorganisms also get their
food from the tree. So when the roots begin to starve the demons of D enter
and cause problems such as wilts, plane tree canker (Ceratocystis fimbriata)
and root rots. Some demons of D, which begin with the letter D, are depletion,
dysfunction, disruption, decomposition, die and death. Also topping affects
the stem because this often leads to top rot and long cracks. Often lightening
gets blamed. What we have seen is wounds from topping weaken tissues from
the trunk to the roots. Then pathogens infect the weakened wood. In these
cases the primary pathogen is the person that removed the tree top. Excessive
sprouting is a sign of low energy reserves. When a tree is topped, it stimulates
excessive sprouting. Very unsightly, i.e., the sprouts I mean. Topping
trees under utility lines causes more sprouts to grow faster. DO NOT PLANT
TREES NEAR UTILITY LINES.
When a tree needs to be topped, it is time for a new tree.
