Japanese knotweed can’t be cured by… the chemicals the state hasn’t yet banned — 2 Comments

  1. I bought a property with some knotweed on 5 years ago. First year I got rid of 90% of it, and the second year probably another 5%. But, I just can’t eradicate it completely. Every year, bits spring up, I spray with glyphosate, they die back and it springs up nearby. Ammonium Sulphamate kills it quite quickly, but you have the same re growth problem. I think the only answer really is a ground poison. Someone I know used plain old salt and seems to have stopped it encroaching on her property.
    The killing season started about a week ago where I live. Today, I saw a bit in an area where I hadn’t seen it for two years. Very frustrating. It’s not a big deal really, I love where I live. It can be viewed a bit like leftists – doesn’t matter how often they’re shown to be wrong, they just keep popping back up again..
