Thistle and Crown Vetch
I made a huge mistake three years ago when I had a new home and they asked to spray crown vetch on my rather steep slope in the back yard sloping down and away from the yard. Now it is taking over the yard and thistles have come up everywhere in the crown vetch and are also encroaching into the yard. I tried pure vinegar on the thistles that were in the yard but they keep coming back. I want to kill off the entire hill and try something else. Two questions. How to kill off the thistles and crown vetch? Any ideas for a good ground cover for full sun?
