Prune Your Elm Trees Starting September 1

Released on August 31, 2016

Saskatchewan’s annual ban on elm tree pruning ends August 31.  Homeowners can prune their elm trees starting September 1.

Pruning elm trees is prohibited from April 1 to August 31 each year to reduce the risk of Dutch elm disease (DED).  The elm bark beetles that spread the disease are most active at this time, and fresh cuts can attract them to healthy trees.

Regular pruning outside the ban period helps keep elm trees healthy and better able to resist all types of disease, including DED.  Removing dead branches makes trees less attractive to elm bark beetles.  Early fall can be a great time for tree maintenance; the weather is generally more pleasant than in early spring and, with leaves still on the trees, it’s easier to spot and remove dead or unhealthy branches.

Proper pruning is important, whether you hire someone or do it yourself.  Pruning incorrectly can spread DED and other tree diseases.  Under provincial regulations, all commercial pruners of elms must complete a recognized training program or be supervised by someone who has.

It is illegal to transport or store elm firewood; the wood attracts beetles that can spread DED.  Dispose of elm wood promptly by burning or burying it in a location approved by the local municipality.  For more information on proper elm disposal, check with your local municipal authority.

For more information, or if you suspect an elm tree may have DED, call the Ministry of Environment’s general inquiry line at 1-800-567-4224.
