I just put down some Gordon’s Barrier I got at Farm and Fleet. Non selective and only need to put it down once per year. It is the only herbicide I use that works immediately (I spray gly, cleth, imox and 2-4d most years). Weeds already wilted and leaned over. It’s got dicamba in it though which makes me nervous. Sprayed the yard with some stuff that had dicamba in it one year and had some house ornamentals and trees that all looked set back one year and I always wondered if that was why.
A gallon of it lasts me a year or two.
