We have a large growth of knotweed on a lot we own across the street from our house. We've been trying for years to eradicate it. My husband has sprayed with bleach, Round Up and other things. Nothing seems to work. He's just been cutting it back lately with a Stihl cutter but it always comes back. We've asked for ideas from several local nurseries but no one seems to have any idea of how to successfully eradicate it. Any suggestions would be appreciated.

We have an elderly neighbour, whose garden is overgrown. Environmental health have advised that there is Japanese knotweed at the top of her garden (approx 20 metres from the house) but I am seeing what looks like bindweed in our garden. I know JN can travel up to 7 metres but can someone confirm this?
