I have a gravel driveway and would like to permanently kill everything that
grows there. I saturated the area with Roundup which killed some of the
weeds but not all, and after two weeks everything was growing again. I
sprayed it with Green Thumb Weed and Grass Killer and that also killed only
some of the weeds. Has anyone had any experience with anything that will
permanently and totally kill weeds and grass and prevent regrowth for an
entire season?

Most weed killers only kil gowing weeds, Seeds are uneffected and will
sprout when ready

Roundup will need reapps..

I use Triox Vegetation killer years ago but it letches away with rain &
watering...............kills plants "downstream" Ooops!
