Japanese Knotweed and the law

Japanese Knotweed legislation in the UK is getting more serious now. The number of official documents issued by British and EU Governments to combat Japanese Knotweed is increasing. It is not an offence to have Japanese Knotweed in your garden if managed properly. But failure to control the weed on your own land or spreading it in the wild could cause serious legal consequences. You can find some information about Japanese Knotweed legislation on our webpage
