This is a great idea. Growing up my parents used black plastic on our fairly large garden. Black mulch seems much more aesthetically pleasing.

  Plus if we're talking about black hardwood mulch, it'll improve the soil as it decomposes.

    The bit that shouldn't surprise me but still does, is the volume change. Add 6 ish cubic metres of mulch and 5 years later is a thin layer of soil comprising maybe 1-2m.
