In an effort to reduce the risk of Dutch elm disease (DED), pruning of elm trees is now prohibited in Saskatchewan with the pruning ban in effect until Aug. 31.
The pruning ban went into effect on April 1, and it was no April Fool’s Day prank.
Elm bark beetles which spread the disease, are most active during this time of year and it is the fresh cuts from pruning that attract the insects and increase the chance of spreading a DED infection.
Proper elm tree pruning outside the annual ban period help keep trees healthy and better able to resist all diseases, including DED. Removing dead and dying elm wood through pruning also helps reduce places for beetles to breed, and curbs their populations. Throughout the year, including during the ban period, DED infected elms should be removed promptly.
Provincial regulations require commercial pruners of elm trees to complete a recognized training program or be under the supervision of someone who has had the training. Improper pruning techniques can spread many tree diseases.
Because of the risk of spreading DED, transporting or storing elm firewood is illegal. Elm wood must be disposed of promptly, using methods and locations chosen by the municipality.
