One of the most common tree diseases in North America is Dutch elm disease. The illness results from an invasive fungus spread by Elm bark beetles. Edmonton is the only place in North America that does not have this issue.  Harmful pests with which Edmonton residents should concern themselves include leaf beetles and sawfly larvae. These insects eat tree leaves during their larval stage, causing significant defoliation. Weevil infestations are another concern. Their larvae eat the bark and foliage of fruit trees, which are common in Edmonton, and cause reduced fruit production, stunted growth, and leaf loss. Our team has the knowledge to identify specific pest infestations and come up with a solution to treat the problem and prescribe the right tree maintenance schedule.
