Japanese knotweed root
The Japanese knotweed root, often referred to as the rhizome, is the underground part of the weed. Click on the video above for hints and tips to help you identify the root. You can also look out for the following:
- The root looks "knotty" with a brown bark.
- Underneath the bark, the knots are an orange-yellow colour.
- If the rhizome is fresh you will be able to snap it.
- Small white roots or buds emerging from the knots (these can grow into new plants if cut up)
