I operate out of Tulsa, OK. I have a client that has decent size sticker (or burweed) problem in his back yard. They are everywhere. Of course they are dormant right now. I have not been doing the weed control part of the business for too long (only a couple of years). Any suggestions as to what to apply to help control them when thinigs start to come back this spring? I was thinking of applying some round up, or possibly Three-Way from Lesco. And of course I am going to hit it with a couple of rounds of pre-m. Any other suggestions? The site in question is about 1500 sq ft.
