Compost kitchen and garden waste. Using compost is an inexpensive way to provide nutrients to your plants, flowers, trees, and vegetables. It also reduces the amount of waste you’re adding to the local landfill. You can buy or make a compost bin, or simply use an out-of-the way corner of your yard. Add anything biodegradable, including grass clippings, raked leaves, raw vegetable and fruit-based kitchen waste (not dairy products, meat, or processed foods) and some shredded newspaper or cardboard. Turn the compost pile frequently and keep it slightly moist to hasten the decomposition process.
