Have you seen this signs?
Do Not Mow Signs are dotting the highway, a program funded by the Ministry of Transportation, to prevent the spread of Knotweed species and other invasive plants along roadways. They indicate to mowers travelling up and down the highway to “Do Not Mow” as there is an invasive plant present, in the case of this sign, destructive knotweed is being flagged. The Coastal ISC contractors then have a chance to treat infestations before it is mowed.
Kudos to Mainroad , our Vancouver Island mowers for their collaboration with this program.
