We received 8 cu-yds of tree trimming waste from ArborDocs through the getchipdrop.com service. He dumped the material in our front yard. It was mostly finely ground limbs, branches, and leaves, with lots of larger material in it too, including logs.  We used to the mulch to create walkways through the area where a future vegetable garden will be.  We put down double layers of cardboard to help block weeds for the first year, and piled the mulch on thick (4-6 inches).  In about 5 years, we should be able to rake the wood chips back and harvest compost, then apply more wood mulch.
