The importance of tree pruning

Tree pruning is the process of removing unwanted or unhealthy branches from a tree to improve its shape, health and productivity. Pruning can also enhance the aesthetic appeal of a tree and prevent potential hazards such as falling limbs or interference with power lines. In this blog post, we will discuss some of the benefits of pruning for healthy plant growth and how to prune your trees properly.

Benefits of Pruning for Trees

Pruning can provide many benefits for trees, such as:

Disease control: By removing diseased, dead or damaged branches, you can prevent the spread of infection and decay to other parts of the tree or nearby plants. Pruning can also improve air circulation and sunlight penetration, which can reduce the risk of fungal diseases.

Bug control: Pruning can help eliminate pest infestations by removing their hiding places and food sources. Some insects can also transmit diseases or cause wounds that make trees more vulnerable to infection.

Safety: Pruning can remove branches that pose a threat to people, property or utility lines. Weak or narrow crotches (the angle where two branches meet) can split and tear wood as the tree ages. Co-dominant leader branches (two main stems growing from the same point) can also split and tear wood, especially in high windsLow-growing branches can obstruct sidewalks, driveways or roads.

Growth: Pruning can stimulate new growth by removing old or weak branches that compete for resources. Pruning can also direct the growth of a tree by shaping its form and structure. For fruit trees, pruning can promote fruit production by enhancing flower bud formation and reducing excess foliage.

How to Prune Trees

Before you start pruning your trees, you should consider some factors such as:

The type of tree: Different types of trees have different pruning requirements and preferences. For example, deciduous trees (ones that lose their leaves in winter) are usually pruned in autumn and winter, while evergreen trees are seldom pruned but may need some trimming in late summerSome trees are prone to bleeding sap if pruned at certain times of the year, such as birches and walnutsSome trees are susceptible to certain diseases if pruned at certain times of the year, such as cherry and plum trees that may get silver leaf disease if pruned from August to April.

The purpose of pruning: You should have a clear goal in mind when pruning your trees. Do you want to improve their health, shape, safety or productivity? Depending on your objective, you may need to prune more or less aggressively. For example, if you want to reduce shading or wind loading on a tree, you may need to thin out some branches; if you want to provide clearance between a tree and a structure, you may need to raise some branches; if you want to improve fruit production on a tree, you may need to remove some old or unproductive branches.

The tools and techniques: You should use sharp and clean tools that are suitable for the size and type of branch you are cutting. You should also follow proper techniques that minimize damage and promote healing on the tree.

For example,

You should make clean cuts close to but not flush with the branch collar (the swollen area where a branch joins another branch or trunk). This preserves the natural protection against decay provided by the collar.

You should avoid making stubs (short pieces of branch left behind after cutting) that can die back and invite infection.

You should avoid tearing bark when cutting large branches by using a three-cut method: first make an undercut about 30 cm away from the branch collar; then make a second cut from above about 5 cm further away from the first cut to remove most of the branch weight; finally make a third cut close to the branch collar to remove the remaining stub.

You should avoid topping (cutting off the top of a tree or main branches) that can result in weak and unsightly growth.


When pruning your trees, you should always start by removing damaged, dead, diseased or weak branches. Then you can proceed to remove or shorten branches that interfere with your pruning objective. You should also take a step back and assess the overall shape and balance of the tree. Work with the natural habit of the tree and avoid going against it. You should also avoid removing too much foliage at once, as this can stress the tree and reduce its vitality.

Pruning can be a rewarding activity that can improve the health and beauty of your trees. However, it can also be a dangerous task that requires skill and knowledge. If you are not confident or experienced in pruning your trees, or if you need to prune large or high branches that require climbing or special equipment, you should hire KIWI Tree & Hedge Services who can do the job safely and effectively.
