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.
During this time, elm bark beetles that spread the disease are most active. Fresh cuts from pruning can attract the insects and increase the chance of a DED infection.
Proper pruning is encouraged, outside the annual ban period. Pruning helps 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.
