Try this solution rather than Roundup:

1 gallon vinegar
1 cup table salt
1 tablespoon detergent

Spray liberally.

I don't know if it will work, but one of my clients and I are trying the newspaper and mulch route. She has a few plants that she's dug up but isn't ready to replace. So, we got newspapers, soaked them and laid them over the plant area. She then put the plastic mesh on top of them and added rocks to look like the rest of her garden. We should know soon enough if this will work. The rest of her yard has the mesh and rocks. The weeds are truly awful throughout, not just along the edges.

If you need to spray near plants, get a gallon milk container, cut the top and bottom off, place it as close to the plant as possible and spray inside the milk jug. Keeps the spray off the plants and lets you spray more of the weeds close to the plants.

No matter what, if the weed is really close to the plant, the only solution is to yank the weed out. So far as I know, there's nothing that is safe to spray by the plants themselves.
