Pruning trees has a number of benefits, not all of them as well known as one would think. In part 1 of our pruning benefits, we gave some tips on how pruning can promote growth as well as some basic steps on how to prune for beginners.
Here we look at some other amazing benefits that pruning promotes and how to tackle them.
Pruning is one of the most essential tasks for maintaining healthy, vibrant trees in your garden or landscape. While it may seem like a simple act of trimming branches, pruning provides many benefits that help trees thrive. Whether you’re a seasoned gardener or a beginner, understanding the advantages of pruning and how to tackle it can ensure your trees grow strong and beautiful for years to come.
The Benefits of Pruning Trees
Promotes Health and Growth
Regular pruning helps remove dead, diseased, or damaged branches that can stifle the tree’s growth and vitality. By cutting away these problem areas, the tree can focus its energy on developing healthy branches and producing more leaves and flowers. Pruning also opens up the tree’s canopy, allowing sunlight and air to circulate more freely, which is crucial for photosynthesis and preventing fungal infections.
Encourages Fruit Production
For fruit-bearing trees, pruning is essential to maximize yield. Removing unproductive or weak branches directs nutrients to the healthiest parts of the tree, promoting larger and more abundant fruit. Additionally, pruning improves the tree’s overall structure, making it easier to harvest fruits when the time comes.
Enhances Appearance
Pruning allows you to shape your trees, ensuring they grow in a balanced, aesthetically pleasing way. Whether you’re maintaining a formal garden or aiming for a natural, flowing landscape, regular pruning helps you control the tree’s size and shape. A well-pruned tree also improves curb appeal and enhances the beauty of your outdoor space.
Prevents Hazards
Overgrown or weak branches can pose significant risks, especially during storms or strong winds. Falling branches can damage property, and power lines, or even pose a threat to people and pets. Pruning reduces these risks by removing potentially dangerous limbs before they become hazardous.
Increases Sunlight and Airflow
By thinning out dense areas of the tree’s canopy, pruning allows more sunlight to penetrate through the branches. This increased sunlight is not only beneficial for the tree itself but also for the surrounding plants and lawn that may struggle in heavy shade. Improved air circulation also helps reduce the risk of pest infestations and disease.
Boosts Longevity
A well-maintained tree has a longer lifespan. Pruning can prevent structural weaknesses that could lead to limb breakage or trunk damage. It also reduces the tree’s susceptibility to pests and disease, further promoting its health and longevity.
How to Tackle Pruning: A Step-by-Step Guide
Now that you know why pruning is essential, let’s explore how to do it right. Here are some tips and steps to guide you through the process:
Know the Right Time to Prune
Deciduous trees (those that lose their leaves in winter) are best pruned in late winter or early spring when the tree is still dormant. This reduces stress on the tree and encourages vigorous growth when spring arrives.
Evergreen trees can be pruned in late spring or early summer after the new growth has emerged.
Flowering trees should be pruned after they’ve finished blooming to avoid cutting off buds that will bloom next season.
Use the Right Tools
Ensure you have the proper pruning tools to avoid damaging your trees:
Pruning shears for small branches (up to 2 cm in diameter)
Loppers for thicker branches (up to 5 cm in diameter)
Pruning saw for large branches (over 5 cm in diameter) Make sure your tools are sharp and clean to make precise cuts and prevent the spread of disease.
Remove Dead or Diseased Branches First
Begin by identifying and removing any dead, dying, or diseased branches. These can be harmful to the tree’s health and should be eliminated as soon as possible. Look for branches that are discolored, brittle, or show signs of decay.
Focus on Problematic Growth
Next, remove any branches that are crossing or growing inward toward the trunk. These branches can rub against each other, causing wounds that invite pests and disease. Also, eliminate any suckers (small shoots that grow from the base of the tree) and water sprouts (vertical shoots that grow from branches), as they take away energy from the main tree.
Maintain the Tree’s Structure
Prune to maintain the tree’s natural structure. For young trees, focus on establishing a strong central leader (the main vertical branch) and evenly spaced branches. For mature trees, thin out excess branches to allow light and air to penetrate the canopy, but avoid over-pruning as this can stress the tree.
Make Clean Cuts
Always make clean, angled cuts just outside the branch collar (the swollen area where the branch meets the trunk). Avoid leaving stubs, as these can lead to decay and attract pests. For larger branches, use the three-cut method:
Make the first cut a few inches away from the trunk on the underside of the branch.
Make the second cut on the top of the branch, slightly further out from the first cut, allowing the branch to fall cleanly.
Make the final cut close to the trunk, just outside the branch collar.
Avoid Over-Pruning
While it may be tempting to trim heavily, especially if the tree is overgrown, over-pruning can do more harm than good. Removing more than 25% of a tree’s canopy in one season can cause stress and weaken the tree. It’s better to prune gradually over a few years to achieve the desired shape.
Pruning is an essential practice for promoting the health, beauty, and safety of your trees. Whether you’re pruning to encourage growth, prevent hazards, or simply to enhance your garden’s appearance, following proper techniques will ensure your trees thrive.
