What is Japanese Knotweed?


Japanese knotweed or J.K. as it is commonly known is a highly invasive, non-native plant found in the U.K. It has the potential to damage buildings, structures and over-power native species, eventually eradicating them from their own environment.

Japanese Knotweed is proscribed under the Wildlife and Countryside Act 1981, making it an offence to allow the plant to spread. All parts of the plant, and any soil contaminated with the rhizome, are classified as "controlled waste" requiring all the "duty of care" requirements under the Environmental Protection Act 1990 to be met.

The Japanese knotweed plant can regenerate from rhizome fragments as small as 0.7gram and can remain dormant in the soil for over four years making a professional and scientific approach to its eradication vital if 100% success is to be guaranteed.
