Composting is a natural way to turn common household items like kitchen scraps and dried leaves into nutrient-rich material that can be used in gardens. In nature, decomposition occurs naturally but can take many years to complete. Home composting is a way to speed up the process by creating the ideal conditions for natural materials to break down. NSF International has these composting tips on how to get started and more! What can I put in my compost? You need two kinds of materials to create compost: greens, which are rich in nitrogen, and browns, which are high in carbon. A suggested ratio is two parts brown to one part green (by volume) , for example two compost bags of dried leaves and one compost bag of grass clippings, or two buckets of shredded newspaper and one bucket of vegetable peelings.
