Pruning Elm Trees in Saskatchewan: Important Guidelines

In Saskatchewan, there is an annual ban on pruning elm trees from April 1 to August 31. This restriction helps prevent the spread of Dutch elm disease (DED), a fatal tree disease caused by a fungus that is transmitted by elm bark beetles.

As temperatures rise, these beetles become more active and are drawn to fresh cuts on trees. Pruning during this period increases the risk of infection and jeopardizes the health of your elms.

To maintain the health of your trees and enhance their resistance to various diseases, including DED, it is advisable to prune them before or after the ban period. Additionally, pruning removes dead and dying wood where elm bark beetles may breed, thus decreasing their population

It is crucial to prune trees correctly to avoid damaging them or spreading diseases. If you hire a professional for pruning, ensure they are qualified. Anyone who prunes elm trees commercially must have completed a recognized training program or be supervised by someone who has.

While you can completely remove an elm tree during the ban period, it is essential to dispose of all elm wood promptly and properly. Contact your local municipality to find out where the designated wood disposal site is in your area.

Moreover, transporting wood can contribute to the spread of DED as well as other insects and diseases. Therefore, it is illegal to use, transport, store, or sell elm firewood. Provincial regulations also restrict the use, transport, storage, and sale of elm logs.
