But if you want some of the volunteer flower seeds since I don't know what the seedlings look like, I would sometimes kill good plants. I sprayed a spot a few years ago, I think that was vinegar, last year I didn't bother but thought I should yank them out. Turned out they were brown-eyed susans which had drifted here from somewhere. I never thought I liked them but they are cute, glad I didn't yank them and maybe can transplant a couple. I got a new spade I hope will be easier on my back but still won't be able to work too long at a time.
