Removing Invasive Japanese Knotweed

Press Release

June 10, 2026

In collaboration with the Invasive Phragmites Control Centre, NFN will begin invasive species treatment work in early August 2026 to remove Japanese Knotweed that has previously been identified and documented by the Environment Department.

We will post treatment signs 24 hours prior to the herbicide application, and they will remain in place for 48 hours (two days) after treatment. These signs will indicate the areas affected and ensure public awareness.

Following the initial treatment, we will revisit the sites to look for re-sprouting or missed plants. If so, we will carry out additional herbicide applications, and mow and cut as needed.

Once the invasive species have been removed, we will remediate and introduce native plants and medicinal species including, Echinacea (Coneflowers), Wild Ginger, and a variety of trees and shrubs such as Eastern White Cedar, American Highbush Cranberry, Red-osier Dogwood, Saskatoon Serviceberry, Nannyberry, and Winterberry. These plants support pollinators, including bees, butterflies, and birds, and provide edible fruit.

If you have Japanese Knotweed on your property and would like treatment, please send us your name, address, and photos of the affected area to:

hollym@nfn.ca or tips@nfn.ca

Miigwech for your cooperation and support.
