What is Tree Pruning?

Tree pruning usually involves the shortening of branches to make the tree smaller and more attractive. This helps the tree to stay strong and healthy. It is important to prune trees accurately to prevent damaging the tree.

Reasons we may Prune a tree:

1. To reduce a trees vulnerability to wind/storm damage

2. To remove diseased or dying branches

3. To make the tree look more attractive

4. To allow more sun light to pass through the tree

5. To manage trees in locations where space is limited

Pruning Techniques

Crown Thinning

Crown Thinning is the process of removing select branches to thin out the fullness of a tree. The smaller/tertiary branches at the outer crown are removed to produce a uniform density of foliage. It is usually confined to broad-leaved species.

Reasons for Crown Thinning:

• Improves light penetration through the canopy- benefits the tree but also reduces unwanted shade in gardens.
• Improves airflow through the canopy and protects the tree from wind- reduces chance of failure during high winds and storms.
• Reduces weight on heavy branches.
• Retains tree’s natural shape.

Crown Reduction

Crown Reduction is the process of reducing the height or spread of the crown. It is one of the most common pruning techniques used by arborists to control the size of the tree whilst maintaining the structure and shape of its crown. Arborists focus on branches on the uppermost portion of the tree canopy, cutting them shorter to decrease the tree height.

Reasons for Crown Reduction:

• Reduce size of a tree when growing in a confined space.
• Prevent tree interfering with power cables or buildings.
• Improves light penetration through the canopy.
• Removes dangerous deadwood.
• Improves shape and growth of tree.
• Improves airflow through the canopy and protects the tree from wind- reduces chance of failure during high winds and storms.
