[permaculture] mulching quackgrass

I've mulched quack and other rhizomatous grasses successfully and unsuccessfully.  The main requirement is that you carefully observe and maintain the site for 2-3 years after treatment and densely plant the area with perennials that can establish quickly enough to keep the grass from re-colonizing.  If the patch is small, black plastic with no openings well overlapping the areas can work, but it has to stay on for a couple years since the roots have stored energy in them.  Otherwise, at least three sheets of cardboard, the larger the better (get them from an appliance store), overlapped at least 1.5 ft, covered with as thick a layer of organic matter as you can manage, planted with fast-growing and dense shade-producing plants (like comfrey, squash, etc.), preferably in multiple layers (a food forest!), should work, providing that you remove any grass that makes it through the mulch, at least monthly.  You want to exhaust all the energy stored in the roots, so the thicker the mulch,
 the better.  Letting grass get above the mulch for any period of time allows it to store more energy in its roots.
Digging out quackgrass is pretty much a waste of time except for small patches with weekly maintenance.  Same with use of chickens or other animals (although this can give you a slight edge in the race).
Have fun,
