Stop the Tree Topping!

Alex Shigo, a New Hampshire-­based plant pathologist  made his name in the 1970s by dissecting an estimated 15,000 trees and debunking the myth of "topping" -- hacking off the tops of branches -- which he believes is at the root of all bad tree care. He is widely considered the father of modern arboriculture.

In the early 1990s he helped persuade the City of Los Angeles to take tree  topping off its list of accepted trimming practices. Dr. Shigo served 15 years as the Chief Scientist in the US Forest Service.
