I feel like we’re talking about different plants because that shouldn’t work at all. Knotweed can survive very harsh condition. Unless you’re digging out the rhizomes, there’s no way to “cut it completely” really.
Is it japanese knotweed? I don’t know it might be a different plant. I have no clue what it’s called in english but it looks exactly like what we had in our garden
