Tips from an arborist: Tree topping is bad

While driving around town recently, I've been noticing a new rash of tree topping. What I mean by "tree topping" is when someone aimlessly cuts a tree in half to reduce it's height. This procedure of tree mutilation is sometimes recommended and provided by so called- tree professionals. I'm amazed and feel sorrow every time I see large beautiful mature trees that have been unnecessarily topped. Through good education and the good practice of professional tree services, tree topping should have stopped years ago.

Tree topping is sometimes recommended by those who provide this service as a means to make your tree "more safe."

In many cases the opposite is true. The tree can actually become more dangerous as the tree resprouts and grows back rapidly to its original height. As a result of topping, trees can develop heart rot, weakly attached branches, accelerated growth, prone to storm damage and insect attack, reduced vigor, increased maintenance and reduced monetary value.

The tree care industry has very specific standards and best management practices when it comes to pruning and other tree care services.

To get the best possible care for your trees, don't be afraid to ask if the tree care provider is a member of a professional organization such as the International Society of Arboriculture, or is a Certified Arborist. These credentials are easily verified through the ISA website. It is also a good idea to verify their Idaho state contractors registration, liability insurance and workman's compensation.
