What Are the Correct Types of Tree Trimming Methods?

The most important thing to know about tree trimming is that it has significant benefits for your trees, including keeping them healthy and strong. These different types of tree trimming are essential for property owners to know to avoid causing damage due to branch failure.

Below, we cover the different pruning techniques as advised by tree trimming professionals in Philadelphia to keep homeowners in the know.

What Are the Different Types of Tree Trimming?

Overall, there are two main types of tree trimming: corrective trimming and developmental trimming.

Corrective pruning is vital for the removal of diseased or dead branches to prevent the spread of further damage throughout the tree. In contrast, arborists carry out developmental trimming on young trees to encourage them to grow in certain directions or towards light sources.

You can perform both types of tree trimming at any time during the year as long as they do not interfere with flowering or fruit-bearing cycles.

Four Specific Types of Tree Trimming Techniques

Crown Clearing

Crown cleaning helps your trees stay healthy and strong. It removes dead, diseased, or damaged branches, helping mature trees get more light and air circulation throughout their crowns.

When you crown clean a tree, you’ll want to remove at least one-third of its branches. Removing branches from the bottom of the trunk up to about three feet from the ground is crucial to ensure that the remaining limbs are properly balanced.

Crown Raising

Crown raising removes the lower lateral branches to provide clearance for pedestrians, vehicles, and nearby structures. This practice also improves lines of sight and safety around your home or business. In addition, it increases the sunlight that reaches your lawn and garden.

Crown raising is particularly useful in protecting property from falling limbs and branches. These hazards can cause damage to cars and homes, so removing any low-hanging branches that could potentially fall on top of them is vital.

Crown Reduction

The goal of crown reduction is to make the tree more manageable by creating more space between branches and leaves. It also helps with sun exposure, improving the tree’s health and growth.

Crown reduction occurs in two ways: removing branches in small specific sections or lopping off entire sections at once. The latter method is more drastic but less expensive because fewer materials are involved in its execution.


Pollarding is a technique that trims trees without killing them. The process involves the removal of branches so that all that remains is a framework of secondary branches along the main stem.

You should start pollarding when your trees are still young and continue regularly as they grow. This trimming provides a constant supply of small diameter poles without killing your tree.

Pollarded trees are ideal for fencing, hedging, or firewood. They also last longer than with other methods because there are fewer weak points where rot can set in.

The benefits of pollarding include:

  • You never have to worry about your tree growing too large or taking up too much space in your yard.
  • It allows you to harvest poles for various uses, including firewood, fencing, and building materials.
