This product takes forever to work. I normally use roundup, but I thought I’d give bioadvanced a try this year with my spot weed removal. Don’t do it, just don’t. While the bottle says "visible results within ONE HOUR”, try ONE WEEK! And the grass isn’t even completely dead at this point, it is just yellowed a bit. I’m super disappointed in this product. I followed the mixing instructions to a T, but I guess I am going to have to double or triple the concentration to get rid of these weeds/grassSee full review
