Composting turns your yard trimmings and vegetable scraps into a nutrient-rich soil amendment for your garden. When used as mulch, compost will reduce your need to water. Use it to enhance the soil, to make a potting mixture, or to add mulch around plants and shrubs.
For Portland residents who want to create their own compost, you can set up a home-based system to capture both scrap materials for your backyard pile – and still include the food for your green Portland Composts! roll cart.
Toss yard debris and vegetable scraps in your backyard composter to get you started – and keep meat, grains, dairy and bones in your green curbside roll cart.
The basic ingredients for compost are “browns,” “greens,” air and water. Browns—like fall leaves and woody materials—are high in carbon, an essential energy source for microorganisms in the compost. Greens—like grass clippings and fruit and vegetable trimmings—are high in nitrogen, an essential nutrient for the decomposer organisms.
