People are going door to door simply giving deals that seem to be something you can't resist. With on the site smooth talking it can be convincing. They are ruining people trees. A tree is a living organism and needs proper care enable to live and give us oxygen. I drive around and see so many trees stub cut or raised improperly or just general bad cuts. Bad cuts cause sprouts, causing stress and damaging your tree. Now your left with a high maintenance tree and one that may be beyond fixable. Consult a second opinion. There are proper ways to prune a small medium or large tree. Years of reading in the field expierence and lots of conversations taught me this. You can save money in the long run by doing it properly one time versus paying a cheap price at first and running into major problems in the future. I am now doing consultations for a small fee, if not going with me at least you have an arborist opinion and a full explanation of why thi gs need cut the way we do them and not just whacking limbs at the trunk or stub cutting them. My job and passion is saving our trees and giving them the proper care they need.god bless
