one year after laying cardboard!
well i had really bad weeds, so i layed cardboard last year to kill em'. i layed the cardboard thick got it wet, and then put loads of lawn clipping on that, wetted that, and then bark on that, and then more watering. well it was all good until now. i have weeds again. some are working their way inbetween the cardboard, and a few are going threw it. i can go out and just pull em out, but that sucks. i can go out and spray them, but then i gotta just pull dead weeds a couple days later. anything i spray the area with only gets the exposed leaves of the weeds, but doesn't stop new ones because it can't get through the grass clippings and cardboard to get down to the new weeds roots! does anyone know a way to get some weed killer down to the weeds. do they make weed killer spikes you can drive into the ground? is laying more bark and cardboard the answer? im kinda confused as to the best way to deal with this!!
