Anything that was once alive will naturally decompose. However, some organic wastes should not be composted at home.

DO compost these items: grass clippings, leaves, plant stalks, hedge trimmings, old potting soil, twigs, annual weeds without seed heads, vegetable scraps, coffee filters, and tea bags.

Do NOT compost these items: diseased plants, weeds with seed heads, invasive weeds such a quack grass and moring glory, pet feces, dead animals, bread and grains, meat or fish parts, dairy products, grease, cooking oil, or oily foods.
