Canadian hemlocks are not considered fast-growing trees. They have a moderate growth rate of about 12 to 24 inches per year. While this may not seem very impressive compared to some other tree species, it is important to remember that the Canadian hemlock is a long-lived tree that can survive for up to 800 years.
In their natural habitat, Canadian hemlocks can grow to be quite tall, reaching heights of 70 feet or more. They also have a spread of 25 to 35 feet, creating a beautiful and majestic presence in the landscape. However, if you prefer to keep your Canadian hemlocks smaller and more manageable, regular pruning is necessary.
Pruning is a technique that involves removing certain branches or parts of a tree to control its growth and shape. By pruning your Canadian hemlocks every year, you can prevent them from reaching their full potential height and spread. This allows you to maintain them at a smaller size that fits better in your garden or landscape.
I have personally worked with Canadian hemlocks in various landscaping projects, and pruning has been an effective method to control their growth. By selectively removing branches that were growing too vigorously or in undesirable directions, I was able to shape the trees to fit the desired aesthetic. This also helped to maintain a more compact and manageable size for the hemlocks.
When pruning Canadian hemlocks, it is important to follow proper techniques to avoid damaging the tree. It is recommended to prune during the dormant season, which is typically late winter or early spring. This minimizes stress on the tree and reduces the risk of disease or insect infestation.
It is also important to note that while pruning can control the size of Canadian hemlocks, it does not necessarily make them grow faster. The growth rate of the tree remains the same, but by removing certain branches, you can redirect the tree’s energy to other areas, promoting a more compact and controlled growth pattern.
Canadian hemlocks are not considered fast-growing trees. They have a moderate growth rate and can reach impressive heights if left unpruned. However, by regularly pruning them, you can keep them small and manageable, shaping them to fit your desired landscape aesthetic.
