What Not to Do When Pruning Your Trees: A Calgary Homeowner Guide

Pruning is an important practice in maintaining the health, appearance, and longevity of trees. However, if not done correctly, it can lead to significant damage, compromising the tree's health and even its survival. As a homeowner in Calgary, it's crucial to understand the best practices for tree pruning to ensure your trees thrive. Below, we explore common mistakes to avoid when pruning trees and how Evergreen LTD’s ISA Certified Arborists can help you do it right.


1. Avoid Pruning at the Wrong Time

Timing is Everything: Pruning at the wrong time can stress your trees, leading to undesirable outcomes. The best time to prune most deciduous trees in Calgary is during the dormant season, typically in late winter. Pruning during this period helps minimize sap loss and reduces the risk of pest infestations and diseases.


2. Avoid Using Improper Tools

Tools Matter: Using the right tools is critical for successful pruning. Sharp, clean tools make precise cuts, which are essential for the tree’s quick and healthy recovery. Dull tools can crush and tear the bark, creating wounds that are difficult for the tree to heal and increasing its vulnerability to disease. Over-reliance on power tools like chainsaws can lead to rough cuts and the removal of too much healthy tissue, which can harm the tree.


3. Avoid Over-Pruning

Less is More: Over-pruning is a common mistake that can severely stress a tree. A good rule of thumb is to never remove more than 25% of a tree’s canopy in a single season. Removing too much foliage reduces the tree’s ability to produce food through photosynthesis, making it more susceptible to pests and diseases. Topping, or cutting back large branches or the tree's main leader, should also be avoided as it weakens the tree’s structure and can lead to its decline. Instead, our arborists recommend using selective thinning or crown reduction techniques to manage size and shape effectively.


4. Avoid Ignoring Tree Anatomy and Growth Patterns

Understanding Tree Structure: Proper pruning requires an understanding of a tree’s natural growth patterns and structure. When making cuts, it’s important to avoid cutting too close to the trunk or leaving too much of a stub. Cuts should be made just outside the branch collar—the swollen area where the branch meets the trunk—and parallel to the branch bark ridge. This allows the tree to seal the wound properly and reduces the risk of disease and decay.


5. Avoid Neglecting Aftercare

Post-Pruning Care: Aftercare is essential for ensuring that the tree recovers well from pruning. While trees have natural mechanisms for sealing wounds, large cuts require special attention. Contrary to popular belief, applying pruning paint or sealants can trap moisture and promote decay. Instead, it’s best to let the tree heal naturally. Additionally, it’s important to monitor the tree for pests and diseases, especially in the weeks following pruning. Regular inspection can help catch problems early before they become serious issues.
