Comment Japanese Knot Weed (Score 5, Informative) 360
We have the same problem in the UK with Japanese Knot Weed. Nothing eats it, it can respawn from the smallest cutting. So you can't burn it, you can't throw it away, you can only poison it. And each stem has to be done individually, and the process needs to be repeated two or three times to kill the bloody thing.
They're talking about introducing some japanese insects that feed on it, but then what's to say they wont prefer strawberries or wheat or something else?
