Japanese Knotweed
Discussion
My OH's parents have a honking great bit of land in there back garden that's directly backing onto an active railway line, but they've not been able to do anything with the land because it's overrun with knotweed, are the Railway responsible for clearing it? (as I recently was told), if not, what's the best way, fire?
It is possible to get rid of, however is very expensive. From memory I think you have to dig down around 5 metres, ie below the roots to make sure its gone for good.
I remember watching a documentary on it & there is a bug/insect of some sort which kills it off, however it has never been released over here for reasons I cannot recall.
Nasty stuff.

I looked a buying a house that was infected with JKW, got some quotes for professional removal. For an area of about 20mx20m I was quoted £6-8000.
The soil has to be removed to a depth of 2m and taken to a specialist (in sealed trucks)for processing.
I was beaten to the purchase and it cost the buyer over £12k for the removal.
Burning is no good as the deep roots will not be affected and the weed will come back.
Nasty stuff!

It would depend where the JKW originated.If you can prove it came from their land then maybe you could get them to clear it or at least pay some of the costs.It has to disposed of by a liscensed company and is not a cheap or quick process
Absolute nightmare with JKW it took me 3 or 4 years to clear it from my patch and I was always on a hiding to nothing as the next door neighbours had it as well
I resorted to Sodium chlorate in the end ,dosing the garden twice over the space of 6 months then covered it with plastic sheeting with some shingle on top of that to hold it in place and make it look a little less industrial.

The majority of Japanese Knotweed has been spread by riverbank erosion, and by mans' activities, such as flytipping garden waste and moving contaminated soil.
Some advice says to chop it then cover with something heavy like an old carpet, you have to be mega careful though as you can cause it to spread very easily.

Railway will not deal with it unless its causing an operational problem such as a signal sighting obstruction.
At the minute we are chopping in and filling the stems with a red liquid (sorry not my dept)
I've seen that on some TV show. Putting something into the stems and it helps to kill off the plant.At the minute we are chopping in and filling the stems with a red liquid (sorry not my dept)
Hate to say it but its a job for the professionals. its actualy a legal offence to plant, move or spread knotweed so dont try to cut it back. As far as i am aware the correct way of killing it off involves some pretty strong stuff which has to be applied repeatedly over the course of some time.
If railtrack dont want to know and you want rid call someone in. there are plenty of companies on tinternet.
