You remember the anecdote about the thermos, you put a hot liquid in it, it keeps it hot, put in a cold liquid, it keeps it cold. HOW DOES IT KNOW WHAT TO DO???? Wood mulch, it *keeps weeds from growing*. So you spread the recommended 3-4 inches to keep the weeds down, but any perennial under the mulch will return. HOW DOES IT KNOW WHAT TO DO???
