Grass

Grass

We've had a major issue for a few years now with grass taking over the garden. They've almost completely eaten up the roses now, it's a shame. When they built the house, they chose burmuda grass (sp?) due to it being drought resistant (and being NC, we have drought issues). Well, the stuff just spreads like crazy. We've tried grass and weed killer, different kinds of mulch, pine straw, and some black garden tarp. Nothing works. It'll even grow under the tarp with no sun! Any ideas on halting to grass? BTW, if anyone would like to see the garden, here are the first blooms of the year: http://public.fotki.com/Scars19/attempts_at_photography/moms-garden-2009/ (copyright 2008)
