Tree Trimming & Pruning

When Should I Prune My Trees?

Most trees can be pruned at any time of the year. The only hindrance is the presence of pests and diseases during warm months that may put your tree at risk. For that reason, the Colorado State Forest Service (CSFS) states that late winter (February-Early March) is the best time to prune most types of trees. Since trees are still dormant (meaning growth is halted) during these months, wounds will close quicker if pruning occurs just before the new growth starts to emerge.

Although late winter is the ideal time for pruning most types of trees, this process can be done at any point during the winter as long as the tree is dormant.

Trees are mostly self-sufficient when it comes to their own structure and removal of deadwood or unnecessary branches.  We are just here to help it along by removing the dead branches, before they can cause damage to property or hurt someone, and by helping to choose a structure for the tree that will be most beneficial to its health in the long run. 

It is recommended that a tree be pruned once every 2-3 years when it is mature. While it is young, a tree should be monitored and pruned as needed every other year to promote healthy structure.

Should I Prune Young Trees?

The short answer to this question is yes, young/newly planted trees need to be trimmed as well, but should be done conservatively. New trees need your guidance to keep them from branching out in the wrong direction and your help to remove torn/broken branches. It is also important for most young trees to maintain a single, dominant leader. Sometimes trees can develop double leaders (also known as co-dominant stems) that can lead to structural weakness so it is best to remove one while the tree is still young.

What Is The Difference Between Pruning and Trimming?

While pruning and trimming sound like they are the same thing they both have different end goals and processes. 

Pruning: Pruning is the method of removing or reducing a tree’s branches or sprouts to improve their health.  Cuts made when pruning are well thought out and are done with the goal of helping the tree by removing deadwood and promoting good structure. 

Trimming: Trimming is done to trees and shrubs to improve aesthetics of the plant.  This method is used to manage the shape and size of the plant overall.  Shrubs and small ornamental trees usually have trimming done to them to make them fit into the landscape better.
