[ARCHIVED] Tree Care in Kneehill County

Tree Assessment

Tree Selection and Care

Selecting Trees

As a mostly prairie county, the majority of trees in Kneehill are planned plantings. When selecting tree species to plant it is important to consider their main purpose, including landscaping, shelterbelts, and agroforestry such as tree farms and berry orchards. A tree’s mature height, lifespan, growth speed, and water tolerance all need to be considered when selecting a species to plant. Finally, the growth zone a tree is started in and conditioned for can affect its survivability, so purchasing trees from local tree farms that have been hardened to specific climate conditions can really help with establishment. For more on selecting tree species for planting visit Agriculture and Agri-Food Canada or contact your local tree farm.

Tree Pests and Disease

There are a number of native and invasive pest and disease species that can be transmitted and infect local tree species. One significant way pests and disease move is through firewood. Transporting firewood may seem harmless, however, moving firewood from one location to another can inadvertently move invasive species to new areas with disastrous results for both forests and urban trees.

Some Pests/Diseases to watch for in Alberta include:

Proper identification and maintenance are key to managing tree pests. This webbook can aid in the identification of some tree pests. If a tree is displaying symptoms and you are in need of identification or treatment recommendations please contact a local arborist.


Regular pruning can aid in tree health, fruit production, and disease removal. It is highly recommended that any pruning that cannot be done from the ground, be done by a professional arborist. For tips on pruning check out this fact sheet or you can purchase this resource book through Alberta Agriculture and Forestry.

Proper sanitization of pruning equipment is key to preventing the spread of disease even across different branches of the same tree. Dipping pruners in bleach for a few seconds between each limb can reduce the transmission of disease and keep your tree healthy for years to come.
