As far as I know, there's not many plants that actually poison other plants (if you know what I mean )
Grass clippings are great too-you must get a few of them...
the nitrogen and anaerobic mat they make easily kills off clumping grasses.
If you have a running grass, I'd say you'll probably need something less...permeable...than prunings-
that stuff is virtually indestructible!
