Is there a sprayable post emergent that I can spray into my mulch beds? I have a lot of mulch. All of the bushes and trees have been there for years. I fight weeds constantly. Right now I am dealing with vetch but I get a ton of different weeds. I am going to put snapshot down this week for a pre em. I use round up as well but it's a pain trying to avoid all of the small plants and bushes so I was hoping for something that I could spray right into the beds and it won't kill the bushes.
