Japanese Knotweed Removed in Westmount Park

Japanese knotweed is an invasive plant that spreads aggressively thanks to a complex root system that clogs the soil, making it difficult for other plants to grow. The City shares information on how to identify, remove, and safely dispose of this plant on the Parks and Green Spaces page.

The City's Public Works team recently identified two colonies of this plant near the lagoon in Westmount Park. The plant material and soil have been carefully removed and placed in black bags. This method allows the heat of the sun to destroy the root fragments and prevent propagation. These bags will be removed from the park shortly, when there is no longer any risk of the plant spreading.

A similar operation to identify and remove Japanese knotweed is planned at Summit Woods in the coming weeks.
