In Wisconsin, mid-winter is an excellent time to prune back deciduous trees and shrubs. As you may already know, pruning shrubbery during the growing season can encourage disease and attract unwanted pests, so unless necessary landscape professionals always choose to do this pruning while shrubbery is dormant.
Since these trees/shrubs have lost their leaves there is now an unobstructed view for this selective pruning process. In order to allow light and air to reach the interior, this process is crucial for the long-term health and will encourage more blooms on flowering trees and shrubs.
Whether you are seeking to contain growth, or even detangle an ungainly structure, mature shrubbery will benefit from this process and enhance the aesthetic appeal of your outdoor living space.
