Grab the Roundup and let them have it! If still alive after 2 weeks, spray them again, perhaps using a double-strength dose. After death, they the plant material will dry up and you should be able to pull it off.

I've started using one of the formulations with diaquat in it which works faster. You can tell in 1 day whether respray is needed in most cases.

THANKS! I'm going to try spraying just to get rid of the grass/weeds, and then after I remove the (hopefully) dead weeds, I'm going to somehow get a triple layer of weed fabric (I'm not normally a fan of weed fabric-hoping this works) under the fence itself and use landscape timbers (and fabic 'pins') to hold it down on both sides of the fence.

Thats the best solution so far or burn it for good.

I gave up and planted Liriope along the fenceline, so far it has choked everything else out.
