Why railway land around Heaton Norris, Edgeley and Cheadle is a common knotweed site, and what neighbouring owners should do.
The main line runs right through Stockport, over the great brick viaduct and on through cuttings and embankments. Rail edges are cut back only now and then, which makes them quiet places for a stand to grow, and fragments can be carried along them or moved by maintenance work.
Check the back boundary every spring and again in midsummer. A dated photograph of any canes beyond the fence is useful evidence.
Railway land belongs to organisations with their own reporting routes. A survey of your side gives you something concrete to send them, with the position of the stand and the date you found it.
