Greens, or nitrogen-rich materials, are often easy to come by. When using an outdoor compost bin, many people have trouble locating enough browns to maintain an appropriate nitrogen to carbon ratio. Here are some suggestions from one our Master Composters for locating some local browns for your pile.
