I have WAY too many greens for my compost which leaves it wet and stinky. Help me think of some browns please. We can't use grass clippings because we are required to have our grass chemically treated, we only drink coffee about once a week, we don't subscribe to a newspaper and we have a yard full of pine trees which means no leaves (just pine straw that we already collect to mulch our beds). I do have a friend who has horses so I could probably get some manure. Suggestions?
