Sheet mulching in process. The next layer is cardboard or paper grain bags -- but I ran out!  (To be continued.)  The following later on that should be compost, and then mulch. Next I would put down grass seed and a sprinkling of topsoil, and water like mad to try to grow a layer of grass that will be impervious to the bur seeds that come in from the junk yard at this corner more than at any other spot on our property.
