April 1-Aug. 31: Ban on Pruning Elm Trees in Effect
To reduce the risk of Dutch elm disease (DED), pruning of elm trees is banned in Saskatchewan from April 1 to Aug. 31. Elm bark beetles that spread the disease are most active during this time of year and fresh cuts from pruning can attract the insects. Provincial regulations require commercial pruners of elm trees to complete a recognized training program or be under the supervision of someone who has. Improper pruning techniques can spread many tree diseases, including DED.
