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. Fresh cuts from pruning can attract the beetles that spread the disease, increasing the chance of an infection. The annual ban is in effect when elm bark beetles are most active.
Pruning is an important part of regular elm tree care and is encouraged, before and after the annual ban period. Timely and proper disposal of the pruned wood is also essential to keep DED from spreading. 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.
