It's too close to that fence and the garage is just on the other side of it, so burning it would be out of the question. Wish I could burn it all down. Might make it a little easier to get to the roots and try to dig them out. But I think I will try the brush killer as you suggest. Don't know why I didn't think of that? Sounds reasonable to me. I'm not sure how deeply the roots go, but it has all kinds of runners. Some are on the surface, but I'd found bamboo coming up quite a ways away from the main clump with no visible runners in sight.The area mine is in is very rocky and hard. So digging it out would be a lot of hard work. I have arthritis and because of it, I'm weaker than I used to be. So may find I can't do the real hard digging anymore. I wouldn't mind keeping some of it if I could find a way to contain it. I think my biggest problem with it is it's not in a good place for it's aggressive habits. We have an acre, so if it were in another part of the yard it may not seem like such a problem. So if you have the right place for it, it just may very well do well for you in your situation. I don't know what cultiver mine is, or how hardy, but if you really want some I'd be happy to send you some for postage, well, that is, if I'm able to dig some out. I could try.
Thank you for your suggestions Frilly.
