Are grass clippings good in compost?
Yes, but not in one big mass. Grass clippings make excellent compost, but they tend to clump together and exclude air. Sprinkle them in shallow layers on your compost. If you have a small compost pile, make the grass-clipping layers two inches or less thick. In a big compost pile, grass layers can be three inches thick. Intersperse the grass layers with layers of dirt or kitchen waste. I just let my grass clippings fall behind the mower, to decompose and turn into nitrogen rich fertilizer. If I am expecting company, I rake up the clippings into a pile near the lawn. Eventually, they decompose. CAUTION: lawns are often treated with Weed and Feed or other broad-leaf weed killers. These poisons persist; they could kill your vegetable plants if the poison is in your compost. Therefore, use only your own unpoisoned lawn clippings (if you have a gardening service, find out what they use).
