Once the snow has gone cover the knotweed with plastic, old carpeting from the garbage anything that will keep it for starting. It will take weeks but worth the effort. Then once it warms up remove everything but the plastic and fry it to death. They do attract butterflies but there are better plants: eupatoriums for instance.

I initially put in a knotweed for privacy. I took it from my mother's in Parry Sound where she has enough space for it not to be so bothersome. Although I had a great experience with it and the monarch butterflies one year {I had over 100 butterflies at a time on the plant in early September} it really chews up my grass. Luckily it hasn't gone under the fence yet. We dug up one root system and it doesn't seem to matter. It's deeper than we can imagine and runners still come up. I'll try smothering it with black plastic. Thanks. Thanks Marjorie,
