How to take care of trees. Who's Right?

Does it seem like every arborist or tree care professional you talk to has a different opinion on the same subject?

 

Why is it that there seems to be no consensus on how to take care of trees, how to prune and how to provide the best treatment of trees with insect or disease problems?

 

THE ISSUE HERE is that standards of tree care have changed dramatically over the last 50 years. Many tree care practices which used to be considered "cutting edge" are now considered to be harmful to trees.

 

No longer is it considered beneficial to do wound painting after pruning trees. Nor is it considered correct to do flush cuts. Tree topping is another "no-no." The tree care industry has changed dramatically, but many of the old ideas about proper tree care are still in circulation and these outdated tree care philosophies continue to contribute to tree care mistakes.
