First, my apologies to those who thought this was a thread about Maryjane... sorry to disappoint. I'm wanting to know who uses what to manage their (weeds) never ending advance on the sanctity of your property. I've tried the propane torch method and that is short lived; just does not get down to their roots, plus the place looks like a war zone. I don't really like using chemicals, but it has been the only real practical method of keeping them at bay. My neighbor introduced me to a product available at McClendon's that is under lock and key at the stores has to be signed for when buying. It, unlike the litany of common off the shelf products, is lights out... like done for the season. So, rather than using less potent stuff, but having to re-apply a dozen times during the season, the one (maybe twice) application of this product probably is more economical in both $$ and time. And, I would venture to guess, the total amount applied ends up being the same....maybe less. I try and use very sparingly, both because it's expensive as hell and trying not to send pesticides into the water tables. I also do a lot of pulling to limit the amount we use...but in some areas like gravel driveways, it's a losing battle. If anyone has come up with some great options, please share.
