And, most astonishingly, mulch provides habitat for beneficial fungi that repel the dreaded root rot organism Phytophthora cinnamomi. Downer is also a mulch myth buster: Adding a layer of mulch does not rob soil of nitrogen. And Eucalyptus mulch? Not a problem. His recommendation is to apply a layer of six inches of...
