I've just identified the "fake bamboo" in our garden as Japanese Knotweed. It's growing at the base of a massive oak tree and along a path where the drains are.
In the UK where I'm from it's a huge problem, and there are very strict regulations about disposing of it when you cut it down in case you inadvertantely spread it even more, and I think it might even be a criminal offense to cause it to grow in a new location. A few Google searches suggest it's not regarded as as much of a problem here in Toronto and that there isn't a special way to dispose of it. Does anyone know anything more about this?
I'm going to have a go at removing it, even though my landlord likes it (I think he likes having a house with solid foundations more!). Any tips for what I know is a nearly impossible job? I've read that spraying the leaves with Roundup in early autumn, then cutting down and injecting the roots and covering the ground with plastic might work.
I need to read up on using pesticides in Toronto near the lake, too.
