Do you want to know the easiest way to have a healthier tree? Prune it. Do you want to know the easiest way to damage that same tree? Prune it. Normally I wouldn’t want to start a blog post with a contradiction but, in this case, I had no choice. The late Dr. Alex Shigo, a biologist and plant pathologist with the United States Forest Service often said that pruning may be the best thing we can do for a tree and the worst thing we can do for a tree. Like anything else, it is all about timing. From the time of planting all the way into its maturity there is a right way and a wrong way to prune. There is also a right time of year and a wrong time of year to prune : especially in Michigan.
