I'm a sheet composter. I have raised rows and alternate grass cuttings with chopped leaves during the growing season. I put it on thick in spots that I get dandelions. I start each growing season off with brown packaging paper topped with wheat straw. I also had to use pine straw this year instead of wheat straw...(thanks to the 2013 southeast spring/summer long, non-stop, torrential "sprinklings".) It was quite pretty!!! Until I add my grass and leaves.
I also use thick brown paper under it all, and I haven't tilled, turned, or aerated in 4 years! I don't have problems with hot spots in my garden or burned plants. I don't have issues with watering either. One down side that I've noticed is that IT STINKS! I mean bad, for the first day or so after cuttings are applied. It can also get a little slippery if I leave my cuttings piled between my rows for more than a day.
I love using grass cuttings in my garden! It makes for close to a weed free garden! I'm also a huge fan of sheet composting! It's made a huge difference in workload for me!
