Elm pruning ban returns April 1 to help stop deadly disease spread

Residents are reminded that Saskatchewan’s annual ban on pruning elm trees begins Wednesday, as part of ongoing efforts to limit the spread of Dutch elm disease.

The provincial restriction runs from April 1 to Aug. 31 each year and prohibits cutting or trimming elm trees during the warmest months, when the risk of infection is highest.

Dutch elm disease, caused by a fungus carried by elm bark beetles, is fatal to infected trees. The disease has already reached communities such as Saskatoon and Outlook.

“With warmer weather, the beetles become more active and are attracted to fresh cuts from pruning, increasing the chances of an infection,” an Environment Department statement said.

Officials note that pruning outside the restricted period helps reduce beetle populations and maintain tree health.

Proper pruning practices are also essential. Anyone hired to prune elm trees in Saskatchewan must complete a recognized training program or work under the supervision of someone who has.

Elm trees may be removed at any time of year, but all wood must be disposed of promptly. Residents are advised to treat or remove stumps and take any elm wood or branches to the Rosetown transfer station, southwest of town, as soon as possible.
