OK, I know this is the wrong forum, but just a quick question. I have a chain link fence around my backyard, and there is about a foot of space between it and the farmer's barbed wire fence along the back side. It is a royal pain to get over the fence and trim, so I generally spray with glyso, but it only lasts for a month or so. Is there something I can buy without an applicator's license that will kill the vegetation for the whole season? Thanks.
