To reduce the risk of Dutch elm disease (DED), pruning of elm trees is prohibited throughout Saskatchewan each year from April 1 until August 31, the time of year when the beetle that spreads the disease is most active. Fresh cuts from pruning can attract elm bark beetles and increase the chance of an infection.
Proper pruning helps keep trees healthy and is encouraged, before and after the annual ban period. The removal of dead and dying elm wood through pruning also helps to reduce beetle breeding habitat and control the beetle population. Proper and timely disposal of the pruned wood is also essential to keep DED from spreading. Throughout the year, including the ban period, prompt removal of infected elms is critical to effective disease management.
Under provincial regulations, commercial pruners of elm trees are required to have taken a recognized training program or be under the supervision of someone who has. Improper pruning techniques can contribute to the spread of many tree diseases, including DED.
Because of the risk of spreading DED, transporting or storing elm firewood is illegal. Any elm wood should be disposed of promptly, using the method and locations chosen by each municipality.
