1. Pruning at the Wrong Time

Mistake: Pruning trees at the wrong time can lead to poor growth or disease.


  • Research the best time to prune the specific type of tree you have.
  • Generally, late winter or early spring is ideal for most trees, as they are dormant and can heal quickly.

2. Over Pruning

Mistake: Removing too much foliage, which can stress the tree.


  • Never remove more than 25% of a tree’s crown in a single season.
  • Focus on dead or diseased branches and thin sparingly for light and air penetration.

3. Topping the Tree

Mistake: Cutting off the top of the tree, which leads to weak new growth.


  • Avoid cutting the main branches or the tree’s leader.
  • Prune by thinning out rather than cutting off the tops.

4. Improper Cutting Technique

Mistake: Making improper cuts can damage the tree and impede its healing.


  • Learn proper pruning techniques, like the three-cut method for large branches.
  • Make cuts at the branch collar to promote healing.

5. Using Dull Tools

  • Regularly sharpen your pruning tools.
  • Ensure clean cuts for better and faster healing.

6. Ignoring Safety

Mistake: Neglecting personal and tree safety.


  • Wear protective gear like gloves and safety glasses.
  • For large trees, consider hiring a professional arborist.

7. Pruning Healthy, Large Branches

Mistake: Cutting large, healthy branches can stress the tree.


  • Focus on dead, diseased, or overcrowded branches.
  • Avoid cutting branches that are over 4-5 inches in diameter unless necessary.
