It is the only thing I will use weedkiller on at all - I am 99.5% organic but I have spent the past six summers injecting it with glyphosphate as it creeps through from next door. Last summer was the first summer no shoots appeared (instead I got suckering lilacs from teh other direction, but I can live with that).
I can't compost. I can't let any garden waste off the premises (any garden materials that have been within ten metres of knotweed in any direction are controlled waste). It can regenerate from mere millimetres.
