No, I don't think that we have the volume and variety you do. But we do have some. Right now my garden has been invaded by horse tail. It arrived two years ago and is spreading throughout the entire yard. I am hoping that mulching and planting lots of stuff will choke and starve it out. It seems to thrive on open ground and depleted soil. Since I have not mulched or done much to amend my soil in years, it was just waiting to happen.
