How can I TRULY kill grass/weeds permanently?

My hubby sprays them with kerosene. Gets rid of them fast.

the simple truth is that if you decide you WANT the stuff to grow there, it won't. It just boggles the mind how vegetation will grow in unwanted places but if you really want a part of yard green...it will stay bare for years!!!

There's only one way and you need two things. One is spray them with a one week eventual root killer. Sprayed on the surfaces, this should work its way down and get ride of most of them Second, do what professional gardeners, and I was one, have always done. A. Buy heavy professional black thick-mill plastic. B. Remove everything except the weeds which should have been lessened, in the area you want weed free. C. Leave the heavy plastic secured in place for two weeks. D. Remove the plastic and replace it with fresh plastic if the maker recommends that. E. Buy bark, small rocks, whatever it takes, and cover the heavy black plastic, onto which you've placed paving stones, bricks or whatever you still want.want, until you've hidden the black completely. F. This is the only permanent solution to your area problem. Good luck.

Get a hoe and dig out the roots.

Clorox and kiss them good-bye.

well you can but you have to have a certification to buy the good stuff. what you want is something that has a high persistance. if it wasnt cracks i would say salt the earth that usually kills everything. but you may have to talk to a certified sprayer to really get rid of them permenantly

Battery acid. Im kidding... Weeds will always find a way of popping up. I have astro turf in my backyard and its awesome. It was really expensive but well worth it. Virtually maint free and no weeds.
