by | Apr 7, 2023 | Tree Services


Tree pruning is essential to tree care and maintenance, promoting healthy growth and minimizing the risk of disease, pests, and storm damage. At Tree Service Buffalo, our experts understand the art and science behind proper tree pruning in Buffalo, NY, and the surrounding areas. This article will explore when, why, and how to prune trees for the best results.

When to Prune Trees

Knowing when to prune trees is critical for promoting optimal health and growth. Here are some general guidelines:

  1. Routine Pruning: The best time for routine pruning is during the dormant season, typically in late winter or early spring, just before new growth begins. Pruning during this time reduces stress on the tree and minimizes the risk of fungal infections and pest infestations.
  2. Summer Pruning: Summer pruning can remove dead, damaged, or diseased branches, improve tree structure, or maintain a desired shape. This type of pruning should be done after seasonal growth has been completed.
  3. Emergency Pruning: Emergency tree pruning may be necessary after a storm or other event that has caused damage to the tree. In these cases, acting quickly to prevent further damage and ensure safety is crucial.

Why Prune Trees

There are several reasons to prune trees, all of which contribute to a tree’s overall health, safety, and aesthetics:

  1. Health: Regular pruning helps maintain tree health by removing dead, damaged, or diseased branches, allowing for better air circulation and sunlight penetration.
  2. Safety: Pruning removes hazardous branches that could fall and cause injury or damage to property. It also reduces the risk of storm damage by improving the tree’s structural stability.
  3. Aesthetics: Pruning helps maintain a tree’s desired shape and size, improving its overall appearance.
  4. Growth Control: Pruning can control tree growth, directing it away from buildings, power lines, or other structures.

How to Prune Trees: Techniques and Tips

Proper tree pruning techniques are essential to promote healthy growth and avoid unnecessary damage. The following techniques and tips can help ensure successful pruning:

Pruning Cuts

  1. Branch Collar Cut: Cut just outside the branch collar, the swollen area where the branch meets the trunk. This cut allows the tree to heal properly and minimizes the risk of decay.
  2. Branch Bark Ridge Cut: For branches that grow at a narrow angle to the trunk, cut just outside the branch bark ridge, the raised area where the branch and trunk tissues meet.

Pruning Tips

  1. Use the Right Tools: Using clean, sharp tools is essential for making clean cuts that minimize damage to the tree. Tools should be disinfected between cuts to prevent the spread of disease.
  2. Prune Selectively: Remove only the necessary branches, taking care not to over-prune, as this can cause stress and weaken the tree. Aim to remove no more than 25% of a tree’s live crown in a single pruning session.
  3. Avoid Topping: Topping, or indiscriminately cutting back the tree’s main branches, can cause significant stress, weak growth, and increased susceptibility to pests and diseases.
