Newmarket’s lush streetscapes are partly thanks to the beautiful, mature trees that line its neighbourhoods. These leafy giants provide shade, improve air quality, and add undeniable charm to the town. But just like any living thing, trees need occasional maintenance, and a crucial part of that care is proper pruning. Indeed, regular, proper tree pruning provides plenty of benefits for your trees, making it a must on several levels. 

However, tree pruning can be a risky business if not done correctly. Taking on this task yourself without the proper knowledge or equipment can lead to serious injury for you, damage to the tree, and even pose a threat to your property or others. 

So, before you grab those loppers and head out to tackle your overgrown branches, here’s a breakdown of the essential dos and don’ts of tree pruning in Newmarket. Always keep this list in mind to ensure you’re prepared before you start any major tree-related projects. 

Do:

  • Identify your tree

Different tree species have different pruning needs. Knowing the type of tree you’re dealing with allows you to make informed decisions about cuts and timing. Resources like the Ontario Ministry of Natural Resources’ tree atlas can help with identification. Take the time to find out what trees you have to ensure you’re giving them the proper type of care.

  • Prune for a reason

Refrain from hacking away at branches for the sake of it. Have a clear purpose in mind, such as removing dead or diseased limbs, improving branch structure, increasing light penetration, or controlling size. Once you have a clear goal, it guides your approach toward pruning your tree as a whole. 

  • Hire a professional arborist

For larger trees, significant pruning jobs, or if you have any doubts about your ability, call in a certified arborist. They have the expertise, experience, and equipment to handle the job safely and effectively. For best results, contact an International Society of Arboriculture (ISA) Certified Arborist – their qualifications ensure they have the proper knowledge and training.

  • Make clean cuts

When pruning yourself, use sharp, proper pruning tools like bypass pruners or loppers. As you work, always make clean cuts just above a bud or branch collar, which is the swollen area where the branch meets the trunk. Avoid flush cuts (cutting right next to the trunk) or stubs, as these can damage the tree and create entry points for disease.

  • Follow the three-cut method

For larger branches (for reference, any branch thicker than your thumb), use the three-cut method to prevent tearing and damage to the bark. Make an undercut 1-2 inches from the branch underside, then a second cut further out to sever the branch. Finally, make a final cut just above the branch collar to remove the stub.

  • Thin, instead of heading

When aiming to reduce branch density and improve light penetration, thin the tree’s branches instead of heading them back. Thinning removes entire branches back to their point of origin, allowing more light to pass through the canopy. Heading involves cutting off the end of a branch, which can stunt growth and encourage weak, sucker growth.

  • Maintain your tools

Sharp tools are essential for clean cuts and safety. Regularly sharpen your pruners and loppers to ensure smooth operation and prevent ragged cuts that can damage the tree. 

  • Dress appropriately

Always wear practical working clothes when doing yard work around the house. Long pants, sturdy closed-toe shoes, and work gloves are a must when pruning. An eye shield or safety glasses are also recommended to protect your eyes from falling debris.

Always be aware of power lines near your trees

  • Be aware of power lines

Always make sure not to prune branches near power lines. Always maintain a safe distance and leave any work near electrical wires to a qualified professional.

Don’t:

  • Prune during the wrong season

One common mistake many homeowners make when it comes to pruning their trees is pruning at the wrong time. The ideal pruning time varies depending on the tree species. Generally, avoid pruning during the active growing season (spring and early summer) for most trees. This is when they’re more susceptible to disease and insect infestation from pruning wounds. Late winter or early spring, when the tree is dormant, is the preferred time for most pruning tasks.

  • Top trees

Topping, which involves cutting off the main leader of a tree to control height, is a harmful practice. It weakens the tree structurally, encourages weak sucker growth, and leaves it more susceptible to disease. Proper pruning techniques can achieve size control without resorting to topping.

Avoid pruning too much of your tree’s canopy

  • Remove too much foliage

Avoid removing more than 25% of a tree’s live canopy in a single pruning session. Removing too much foliage can stress the tree and hinder its ability to produce food.

  • Use improper tools

Using dull or inadequate tools can lead to ragged cuts, increased risk of injury, and impede your ability to finish the job effectively.

  • Climb excessively tall trees

If you can’t reach a branch comfortably from the ground, don’t attempt to climb the tree. Leave it to a professional with the proper climbing equipment and safety training.

  • Prune trees with visible signs of disease

If your tree shows signs of disease, such as fungal growths, oozing sap, or discoloured leaves, avoid attempting to prune it yourself. Improper pruning can spread the disease further. Instead, consult with a certified arborist who can diagnose the problem and recommend the best course of action, which might include specific pruning techniques or even tree removal in extreme cases.

  • Neglect safety precautions

Always prioritize safety when pruning. Don’t work alone, especially on large projects. Have someone assist you or be readily available in case of an accident. Be mindful of your surroundings, ensure there are no people or pets below the work area who could be injured by falling branches. And finally, avoid overestimating your abilities. If a task seems too daunting, err on the side of caution and call a professional.

  • Prune for purely cosmetic reasons

While aesthetics can be a consideration, pruning should primarily be done for the health and well-being of the tree. Focus on removing dead, diseased, or problematic branches rather than solely shaping the tree for appearance.

  • Dispose of prunings improperly

Refrain from leaving branches and debris scattered around the base of the tree. Any flotsam left at that area can create a haven for pests and diseases. Chip them up for use as mulch, bundle them for collection by your municipality’s yard waste program, or take them to a local composting facility.

  • Neglect to plan for the future

Consider the mature size of the tree when pruning young trees. Proper pruning techniques when the tree is young can help avoid major problems down the road, such as branches interfering with power lines or buildings.

Remember, a healthy tree is a beautiful tree. By following these dos and don’ts of tree pruning in Newmarket, you can ensure the safety of yourself and others, while promoting the health and longevity of your valuable trees.
