Japanese Knotweed

About This Project

Japanese Knotweed

Japanese knotweed is a large herbaceous perennial plant that has been listed by the World Conservation Union as one of the world’s worst invasive species. While stems may reach a maximum height of 3–4m each growing season, The invasive root system and strong growth can damage concrete foundations, buildings, flood defenses, roads, paving and retaining walls.

We have a system in place where through careful on site management and selection of the correct chemicals it is possible to control and eradicate this persistent plant across two to three seasons.
