The incredible spring growing season we’ve had here in the New York area has produced a thick, heavy canopy for our trees and shrubs. In many cases, this is too much of a good thing. We’ve been seeing a lot of trees that have too much leafy weight to be safely supported by the branches, making them vulnerable to snapping off, and putting stress on the tree’s health. We're also still finding branches damaged by last fall’s storms either hung up in other branches or ready to break off.
And there are several other good reasons to “Prune in June.” Selective pruning helps to maintain your plantings by stimulating healthy new growth, enhancing the form and beauty of your trees or shrubs. Right after the spring growth is also the right time to prune to create a thicker privacy screen. And of course, selectively pruning the tree canopy will allow more light to reach your lawn, shrubs and perennials.
