What is the difference between “organic” mulch and “organically produced” mulch?

An organic mulch is simply one that is made from plant materials, such as wood, compost, straw or leaves. Unlike plastic, rock or shredded tires, it will break down to provide nutrients and improve soil. A mulch has only been "organically produced" if the company that made it meets standards like those that govern organic food producers. It cannot contain pesticides or herbicides.
