I have noticed a small amount of Fallopia (Japanese Knotweed) growing along the roadside of my property. It has a very long way to go before it would be in my yard. Honestly, I've seen it on neighbors' property, and it does create a nice border. I realize that it is a very invasive plant, but I hate to tear it out because I've been searching for ways to block the veiw of my yard from the road. My question is, is there a way to contain it, like there is with bamboo. Does anyone know how deep it's roots are? I was thinking of possibly buring some sort of a barrier in the ground so that it doesn't spread into my yard. It would actually have to grow in about 40' to do this from where it is now. Thanks for any help.
