Why is Japanese Knotweed such a problem?

Japanese Knotweed is widely recognised as one of the most prolific species to be introduced into the UK and as such, requires specialist methods to control it. These methods include a range of options from herbicide application to root-proof membranes and excavation.

It can take a number of years to fully eradicate and any soil involved with Japanese Knotweed is classed as controlled waste and if moved, must be done so under tight controls to avoid spreading the problem to other sites.

People who do not manage Japanese Knotweed on their properties can face prosecution.
