The annual elm pruning ban in Alberta is over
The only time it is legal to prune elms in Alberta is between October 1 and March 31. The Society to Prevent Dutch Elm Disease (STOPDED) recommends that all trees be pruned by a professional arborist such as an ISA Certified Arborist. They can determine what type of pruning is necessary to maintain or improve the health, appearance and safety of your trees. www.stopded.org.
