Putting Japanese Knotweed Control into Context

Where Japanese knotweed eradication is required the control program must include monitoring since eradication will never occur unless the root (rhizome) is in a state of advanced decay. Too often so-called specialists will mislead clients into thinking that Japanese knotweed is eradicated once there is no top growth. Therefore it is wise to seek the best advice, after all this is free at PBA and will allow you to make an Informed decision.
