Lol good luck with that!
Well we had it in our backyard and did exactly that. It's not there anymore.
Then you're lucky. Our government tried this and failed miserably. The rhizomes grow pretty deep and are very resistant, so burning and cutting shouldn't really do much.
Well if you cut it completely every day or every feq days it will run out of stored energy eventually and stop growing.
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
