Elm Pruning Ban

To prevent the spread of Dutch Elm Disease (DED), a province-wide pruning ban for all species of elm trees will be in effect from April 1 to September 30.  Pruning elm trees during this time period creates wounds that could provide entry sites for Elm Bark Beetles, a carrier of the DED fungus. 

Provincial regulations prohibit the storage, sale, or transport of elm wood.  For more information on DED visit

Watch for symptoms of Dutch Elm Disease on elm trees in your neighbourhood.  Elm trees infected last season may not leaf out this spring.  From mid-June through July the leaves on infected trees will wilt, curl up and turn brown.  Leaves on trees infected late in the season will turn yellow and drop prematurely.

Report elm trees displaying these symptoms to the City of Lethbridge Dutch Elm Disease can call 311 or the Provincial Hotline: 1-877-837-ELMS (3567).

For Public Inquiries:

Call 311 |  Monday to Friday, 8 a.m. to 4:30 p.m.
