The Ash tree, a common tree species in our province, is being immensely threatened by the ash borer. As it multiplies quickly and virtually kills every tree it infects, it poses a major worry for both municipalities and private property owners alike.
If you have an Ash tree, be on the lookout for loss of canopy as that tends to be a symptom of infection. It only takes as little as one year after infection for the tree to lose its leaves and die. This poses a danger for any structures surrounding it, as its roots and trunks are severely weakened due to the wood becoming “punky and soft”, as written in Waterloo’s The Record’s article.
If you have an ash tree, and it is still not infected, you can immunize by injecting insecticides, but bear in mind, you will have to do this quite regularly- every 2 years for life. However, due to this pest’s successful reproductive rate, the chances that your ash tree is already infected, are quite high.
You can head over to Toronto and Region Conservation for the Living City on how the insect is affecting trees in our city and what we can do to help.
