(HIGH RIVER, AB) Elm tree pruning season officially ends after Sunday, March 31. Pruning includes any activity that involves removal of dead, damaged, or diseased branches from healthy elm trees.

Alberta boasts the world's largest population of disease-free elm trees. To safeguard this, the Town of High River adheres to provincial regulations, banning elm pruning from April 1 to September 30.

Elm bark beetles are active between these times and can be attracted to the scent of fresh cuts. These beetles can cause infections in healthy elm trees. Once elm bark beetles infect the tree, it will die within a year.

Proper pruning, performed by a qualified arborist, is essential in maintaining a healthy elm population. The following are things a homeowner should look for when hiring an arborist:

  • Check for ISA arborist certification
  • Ask for proof of insurance
  • Check for necessary permits and licenses
  • Ask for references
  • Get more than one estimate
  • Be wary of individuals who go door-to-door and offer bargains for performing tree work
