In Saskatchewan, there is a ban in place on pruning elm trees from April 1 to August 31 every year in an effort to reduce the threat of Dutch elm disease, a fungal disease that is spread by elm bark beetles. The fungus does not spread through air or water but it is carried by beetles or transmitted through grafted roots. The elm bark beetles are quite active during the time of pruning prohibition and fresh cuts on the trees can attract them to healthier trees.
Homeowners are allowed to prune their elm trees starting September 1 to ensure their health and resistance to all types of diseases including DED. Early fall instead of early spring is the proper time to prune trees because by removing the dead branches, the tree becomes less attractive to the elm bark beetles. Tree maintenance is easier and more convenient when the weather is pleasant because the leaves are still on the trees and dry unhealthy branches are particularly noticeable.
Pruning is a type of tree maintenance that can be handled by the homeowner or an arborist hired for the job. However, it is suggested to work with expert arborists who understand the proper process of removing dead and broken branches. Incorrect pruning of elm trees can easily spread DED and other tree diseases. Provincial regulations require that all commercial pruners of elm trees must have completed a recognized training program or supervised by someone who has undergone extensive training.
Transportation and storage of elm wood for firewood is also prohibited because it can attract elm bark beetles that spread DED diseases. After pruning, the dead branches must be promptly burned or buried in a location that has the approval of the local municipality. There are other ways of approved disposal allowed by the provincial laws.
