At Grinders Tree Service, we pride ourselves in maintaining a professional level of service for our clients. That includes following all of the City of Edmonton standards and bylaws when it comes to elm pruning and removals. If you didn’t know, elm trees can not be pruned March 31st – October 1st of any year. The fresh cuts made during this time attract an elm bark beetle that can carry a fungal disease that is deadly to elm trees.
Black knot (Apiosporina morbosa) is a spore-borne fungal disease that affects trees in the Cherry family (Prunus spp). The Black Knot spores are spread when damp or wet conditions are present in the environment. They are able to spread when the spores attach to birds, or humans. Things such as splashing water or the wind blowing can also cause spores to spread.
