OH NO!!! I feel for you! It's all over here in the PNW. Luckily, it's not on this property. Here, besides the blackberries, I think the Creeping Buttercup is the worst and it's so hard to remove. There's more of it than there is grass...but the grass is all weed grass, including Reed Canary Grass. I'm still working on a raised bed, but I'm sure the CB will make its way up there eventually.
