The pruning ban for elms is now in effect. The ban is part of an effort to keep Dutch elm disease (DED) out of Alberta. Any pruned elm branches or firewood should have been burned, buried, or chipped by March 31.
“If elm trees are pruned during the pruning ban period, beetles that are active at this time can be attracted to the scent of the fresh wound and possibly infect an otherwise healthy elm with DED. Once an elm tree is infected with DED, it will die within that year,” said Janet Feddes-Calpas, executive director of the Society to Prevent Dutch Elm Disease.
The ban is in place until Sept. 30.
