I would be interested in an alternative to Round Up that works here in the deep south. I've tried all those recipes with Dawn, salt, vinegar, etc. in various combinations, some boiling, etc. It kills the green parts, but, then in a day or two it is all back like it was on steroids!! I pull as many as possible, but, anyone down here will tell you in a minute, weeds will take over again. We have done a good job in the flower beds with pine straw. that has cut down tremendously on the weeds. Weeds come up through landscape fabric, two layers with the top part of the grass/weedy part scraped off first. Go figure. So, will be interested in a good alternative.
