The annual restriction on pruning all types of elm trees is over at the end of August. Homeowners are encouraged to prune their elms, beginning September 1.

Each year, pruning of elm trees is prohibited from April 1 to August 31 to reduce the risk of Dutch elm disease (DED). The elm bark beetles that spread the deadly disease are most active during this period and fresh cuts attract them.

Regular pruning, outside the ban period, helps keep trees healthy and better able to resist all types of diseases, including Dutch elm disease. Removing dead wood also makes trees less attractive to elm bark beetles.

The late summer and early fall can be a good time for tree maintenance, with generally more pleasant and predictable weather than in the early spring. The leaves on the trees also making it easier to spot and remove dead or unhealthy branches.

Provincial regulations require commercial pruners of elm trees to complete a recognized training program or be under the supervision of someone who has. Improper pruning techniques can contribute to the spread of many tree diseases, including Dutch elm disease.

Due to the risk of spreading DED, transporting or storing elm firewood is illegal. Any elm wood should be disposed of promptly by burning or burying it in a location approved by the municipality. If you require additional information regarding designated disposal areas and methods in your area, contact your local municipal authority.

For more information about Dutch elm disease or to report a suspicious tree, call 1-800-SASK ELM or your local municipal office.
