I'm looking to buy some land in a woodland that needs cleared before building and wanted to check that there is no knotweed. There is a lot of Rhododendron and some bracken to clear but im not sure what knotweed would look like at this time of year? The land has been left for 30 years unattended so if it was present, would it be all over or just in certain areas?
