Trees play a crucial role in our cities. Your Kozy Arborist provides services for every aspect of your tree’s life to help these plants thrive in your environment.


We plant locally grown trees from the best local growers. We strive to plant native tree species because they are better adapted to our ecosystem. There are many tree defects that may occur throughout a tree’s lifespan, a large amount of these defects relate back to improper tree planting. This is why a proper planting technique is very important. Planting a tree properly is much more advanced than just making a hole and placing a tree in it.

Juvenile Tree Pruning

Juvenile trees require structurally pruning. This ensures that the tree will grow properly and are set up for a long, prosperous life. Pruning juvenile trees is extremely important, and unfortunately, often overlooked. Many problems with mature trees arise from not being pruned while juvenile. Poor branch structure can cause major tree failures which may result in serious damage, and spending thousands of dollars to clean up.

A young tree will react quicker and stronger to pruning, compared to mature trees. The pruning cuts that are made on juvenile trees grow over well, and aren’t even visible after a few years.

If a tree is improperly pruned it may be detrimental to the prosperity of your tree. Reasons to prune a juvenile tree include: promoting future ground clearance, future clearance from buildings and obstacles, and future structural integrity.

Mature Tree Pruning

Mature trees often have lots of deadwood which can fall without notice. If these branches are even just a few inches in diameter; they can cause major damage and/or serious injury.

Reasons to prune a mature tree are for deadwood or crown cleaning, to increase light penetration, to reduce risk to targets, to improve ground clearance, as well as to create building and obstacle clearance. 

Tree Removal

Tree removal is the last step for a tree in an urban setting. Reasons to remove a tree is if it is dead or hazardous, interfering with the growth of another tree or to make way for construction. We do not remove trees because of the burden to clean up their leaves or fruits.

Tree Risk Assessment

A tree risk assessment determines the potential risk of failure for your tree. This tree risk assessment consists of: identifying potential targets, assessing site conditions, inspecting the tree’s health and species profile along with its defects and conditions, labelling its risk categorization, listing load factors, and then creating notes with mitigation options.

An assessment will create a plan of action to ensure the risk will be mitigated. In some cases an advanced tree inspection may be suggested. Some advanced tree inspections include an aerial climbing inspection and a resistograph. Kozy recommends requesting a tree risk assessment if there are targets under the tree or there is potential risk of failure.

Tree Inventory

A tree inventory is a tool to manage and help maintain a property with many trees. It’s best to start a log of your tree’s health as soon as possible.

A tree inventory helps to: record the tree’s species and diameter, manage site conditions, diagnose defects in your tree, as well as record its risks and hazards. If you maintain a large property, need to identify a budget for future tree work or own high valued trees, Kozy recommends requesting a tree inventory.

Tree Management on Construction Sites

While a property is undergoing development, the plan may be to leave a tree in place. Unfortunately, the construction around the tree can have a major toll on its health. Consulting with an arborist about your tree and the development plan is very important before starting your construction.

Retrieval from Trees

Climbing trees is a dangerous activity. If there is something you need taken out of a tree, do not do it yourself. Our trained Kozy arborist can safely climb and retrieve whatever it may be.
