Late last week I noticed some thistles growing in the gravel beside a walk and I pulled them out by their roots. Thistles are a bane to this area, a noxious weed, and I detest them. I dropped them, roots and all, on a paved walkway intending to dispose of them after they'd died.
I was near that part of the back yard today and checked on them. Not only are they not dead, they're blooming. After having been pulled up by the root. I admire tenacity and perseverance, I do. Is there nothing that will kill a thistle short of burning?
