The City is continuing its comprehensive, multi-year approach to address knotweed. Knotweed is an invasive plant that rapidly grows, spreads, and dominates its environment. It can impact the natural environment, infrastructure and road safety. Knotweed is very difficult to eradicate once established.
For knotweed on City lands, action is focused on:
Spread Prevention: Knotweed can re-sprout from very small plant and root fragments, and mowing or flailing can contribute to spread. Mowing barriers and signs have been installed in key areas to serve as a reminder of spread prevention.
Removal: Chemical treatment is a last-resort option and is considered to be the only effective method for controlling knotweed. Treatment is being done by certified professionals and in accordance with all applicable federal, provincial and municipal regulations. Signage will be posted at all treatment sites before and after application.
For knotweed on private property, the City encourages owners to help us work towards the eradication of this invasive plant by hiring a certified pesticide applicator experienced in knotweed control.
