Composting Yard Waste

Woman and man building a compost pile


Fallen leaves, grass clippings, shrubbery trimmings and other landscape products, so-called “yard waste,” can be transformed into a valuable resource called compost. Compost improves the structure and moisture retention of most garden soils. By recycling yard wastes at home, you can reduce the amount of solid waste entering landfills. These efforts benefit the entire community and ultimately benefit your landscape.
