City of Lake Forest, IL

Tree pruning is one of the most important components of maintaining a healthy urban forest. Pruning removes dead and/or competing branches to encourage healthy new growth and maturation. It also removes and reduces weak branches that can become a safety hazard. The process maximizes a tree’s value and maintains numerous environmental and community benefits.

While City crews prune trees on parkways and in public areas throughout the winter, the City uses a contractor to do additional pruning in order to accomplish more during the time of year when it's best to prune trees.
