Hi, has anybody had any experience of dealing with Network Rail on Japanese knotweed? I have reported it, and they claim to be spraying it, but the thing keeps growing and spreading. This has been going on for 3 years now, and some years they haven't sprayed it twice as promised. They advised the spraying would ensure it wouldn't spread further, but it has!!! I am at my wits end. I have contacted them so many times, but just seem to stuck in a loop with them. They claim to be spraying, and that there is no further growth. I keep chasing them for photos, or even confirming dates prior to spraying so I can be there to ensure they are spraying in the right place. I live near Honor Oak Park Station. Any guidance you may have would be really appreciated.
