Smack dab in the middle of the slope, lived a particularly pernicious mass of knotweed rhizomes. We had been trying to cut it back for a couple of years, we tried to dig out as much as we could, however, none of that seemed to be working. Finally, I took a big black tarp, and just covered it up. I weighted down the tarp around its edges and a little of its middle. I didn’t want to cover the whole thing because I wanted the sun to make it as hot as possible.
This tarp was there for quite a while, but it did the trick!
