Hi,
We have moved to a 10 acre site in the East of England and are confronted with a roughly 20 metre square area under some ash and willow that is covered in Japanese knotweed. The advice to deal with it seems to be to either dig out a massive amount of soil, put a membrane down a few feet below, and bring in fresh soil on top - or to use chemicals to get rid of it over time. Both of which might or might not work.
I am currently experimenting with putting our two kune kune pigs on there to see what they think of it but am wary it could make the problem worse.
Does anyone know of a good permie solution to this invasive problem? Any ideas much appreciated!
Many thanks indeed
Ben
