Got my last bit of work done with this rental today. I move and mix my leaf/grass/perennial pile around in a "U" shape until i get to good workable not hot compost. It usually take 2-3 moves and a year and half or so. It would go quicker if I moved it more. The material we bring back and then I sell the compost. It helps a bunch in these newer subdivisions that have "soil", basically concrete and junk. The pile behind the hoe is finished compost. It might be hard to tell, but it's deep and probably 300+ cubic yards. Then there's another couple hundred in leaves, etc. We used to bag more grass and the green would break down the leaves much faster, not now though. Anybody need 250 yards of compost?
