The Benefits Of Crown Thinning And Crown Raising in Edmonton
Sometimes, natural growth isn’t the best thing for your tree. From wayward branches to crowding other trees or structures, there will be times when it’s necessary to trim back or prune a tree. But through services like crown thinning or raising, a local trusted arborist can help you maintain your deciduous tree’s overall appearance and health.
Often done together, these pruning methods focus on different parts of your tree to reduce the bulkiness of the canopy, provide better clearance, and improve the health of your tree.
What Is Crown Thinning?
Tree crown thinning is the process of removing select branches from a tree’s canopy in order to thin out the foliage and allow more light and air to penetrate through the tree. This type of pruning focuses on the upper portion of the tree in order to maintain its overall shape and health.
Crown thinning isn’t to be confused with crown reduction, as crown reduction involves reducing the overall size of the tree’s canopy by pruning back the branches to decrease its height and spread. While in crown thinning, you are reducing the density of the tree’s crown by selectively removing branches and foliage to allow more light and air to penetrate through the canopy, unlike crown reduction, it does not aim to alter the shape or size of the tree’s canopy. Crown thinning is primarily done to improve the tree’s health and overall structure.
That Sounds Like Tree Topping To Me
Crown thinning is nothing like tree topping. While tree topping refers to the indiscriminate removal of a significant portion of the leafy crown or canopy, crown thinning is a selective pruning technique that involves removing specific branches to reduce the density of the crown while maintaining its natural shape in order to promote better health.
Tree topping, on the other hand, does not improve the tree’s health. In fact, it’s harmful to the tree, and can lead to a weakened structure and increased vulnerability to disease and pests. It’s important to prioritize proper pruning techniques, such as crown thinning or crown raising, that promote the tree’s natural growth and long-term health.
What is Crown Raising?
Tree crown raising, or crown lifting, refers to the process of removing the lower branches on a tree, creating the appearance of a raised canopy, and this type of tree pruning method is done with the goal of providing better access and clearance beneath the tree.
While crown raising may also give the appearance of a reduced canopy, unlike crown thinning and crown reduction, which involve upper limb and entire canopy respectively, crown raising is focused on the select removal of lower branches to improve vertical clearance beneath the tree rather than reducing the overall shape of the canopy. This technique is commonly employed to address issues related to height restrictions or obstructed views.
However, crown raising may not work well for every tree. Tree branches stemming off low on the trunk may not respond well to crown raising because of the potential for weak attachment points and structural instability. Removing too many low limbs can add stress to the top of the tree, especially during windstorms, as there’s no counteracting balance to prevent the tree from breaking or falling. Additionally, limbs that are too large are not good candidates for removal, as they play a crucial role in the overall stability and health of the tree.
Because of these restrictions, it is often better to perform crown raising on young trees, and to remove or thin out only a few branches at a time, allowing the tree to adjust gradually and minimizing stress.
Benefits Of Crown Thinning and Crown Raising
Both crown thinning and crown raising are a form of maintenance, helping to keep your tree in its best condition and preventing potential hazards, keeping both your tree and your property safe. These services are often done in tandem, as they both contribute to the overall health and appearance of the tree while focusing on different areas. By maintaining a proper balance of foliage density and lifting lower branches, the tree can thrive while minimizing risks.
Some of the benefits of crown thinning and raising include:
Improve Overall Health
Crown thinning and crown raising can improve your tree’s health by promoting better airflow and light penetration, reducing the risk of disease and improving the overall aesthetics of the tree. A cumbersome, heavy, or sagging canopy can prevent the tree from receiving adequate sunlight and hinder its growth potential. By strategically thinning or raising the crown, the tree can thrive with a more balanced and functional canopy.
These forms of pruning can also help prevent disease or pest infestations, as they create an environment that is less conducive to the growth and spread of pathogens or pests. Pruning can lessen the risk of disease by removing dead limbs or decaying branches. By getting rid of these branches through crown thinning or raising, more resources can be allocated to healthier branches and growth and fighting off diseases. Pests are also less likely to thrive in a well-pruned tree, as the removal of dead or diseased branches eliminates potential habitats and food sources.
Additionally, for flowering or fruit trees, crown raising or crown thinning can help increase production of blooms or fruits by allowing more sunlight to reach the lower branches, stimulating the tree’s reproductive processes, resulting in a healthier and more fruitful tree.
Increase Safety
By removing or reducing heavy branches, you can increase safety around your tree. Crown raising removes lower branches, providing clearance and preventing head injuries from whacking against lower branches. Crown thinning reduces the density of the upper branches and heavy limbs, allowing for better air movement and reducing the risk of branch breakage during storms.
Additionally, removing broken branches or dead tissue in your tree helps to strengthen it by reducing stress levels and diverting resources to strengthen healthy branches, helping to improve limb strength and preventing further damage.
Let In Light
Crown thinning and crown raising allow for sunlight to reach the lower parts of your tree easier. This not only can improve its own health, but improves the health of the surrounding ground and yard.
A heavy canopy of leaves lessens the amount of light and other resources from hitting the ground. This in turn prevents growth of nearby grass or surrounding foliage, and can create a damp and shady environment underneath the canopy. While trees are expected to provide some shade, too much can have a detrimental effect on its surroundings, hindering the growth of plants and ultimately impacting the entire food chain.
As both crown thinning and crown raising helps thin out or reduce the canopy, this creates more opportunities for light to get through and hit the ground, promoting healthier growth among the understory vegetation, improving air circulation, and reducing the risk of disease or pest infestations.
Improve Appearance
While the goal of most tree pruning services is to promote the health of your tree, a natural consequence of crown thinning and crown raising is improving the shape of your tree. A tree that’s undergone one or both services will have a less dense canopy that isn’t as sprawling or low to the ground as before. This helps it appear healthier and tidier, while providing more room around your tree and better access to surrounding plants, areas and views.
Improve Accessibility
It can be hard to navigate around a tree with a dense canopy or low-hanging branches. By removing or reducing these through crown thinning or raising, you can improve accessibility around your tree.
Crown thinning provides better access to the top of your tree, while crown raising removes cumbersome lower branches that may get in your way. These services, especially when removing lower branches, can provide ease-of-access around your tree, providing clearance for foot traffic, vehicles, and structures. When your tree has a more open canopy, it’s easier to navigate around, as there’s less risk of branches obstructing pathways or structures.
Contact The Tree Care Professionals
When you have an ISA-licensed arborist performing crown thinning or raising, your tree’s health and well-being are their top priority. While many Edmonton homeowners can prune their own trees, you have to be careful of where and how much you cut. Cutting too much off your tree can harm its health, and cutting the wrong branch at the wrong time could result in further injury to your or the trees. A professional arborist will be able to tell which branches to trim back or get rid of, and do so safely while benefiting the health of your tree.
