Elm Tree Pruning Season

High River – Alberta currently has the largest population of disease-free Elm trees in the world. For this reason, the Town of High River is committed to following the rules and regulations set by the province, which prohibits the pruning of Elms between April 1 and September 30.

Elm bark beetles (EBB) 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.

The pruning of Elm trees is permitted and encouraged between October 1 to March 31. This pruning includes the removal of dead, damaged, or diseased branches from healthy Elm trees.

Proper pruning is essential in maintaining a healthy Elm population. If you need assistance there are qualified professionals in the nearby area. 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
