Japanese Knotweed is one of the most invasive plant species in the UK and has many guises, depending on the time of the year. Identifying it is not always easy, even if you know what to look for. While an Agronomist will know the differences between Knotweed and commonly misidentified plants, these may not be so obvious to a less experienced person. Below are some images and descriptions of the main features of Japanese Knotweed that should help you identify it, but should you remain unsure Landtech (UK) Limited can help with our FREE Japanese Knotweed Identification Service.
The rhizome is the underground part of the plant. Rhizomes have a twig-like appearance with a dark brown exterior. The texture of the outer bark is leathery with nodes at 1-2cm spacing, slightly enlarged and ‘knotty’.
When the bark is removed, the tissue is pale orange/yellow. They are brittle when fresh and break easily like a carrot. Young rhizomes are white and very soft.
