PERFORMANCE Mulch

Why buy Mulch from Cosmic Stone at $47-per yard when you can buy at a big box store for about $4 per bag?

  • Price - about the same - You need about 13 two cubic foot bags to total a yard.  At $4 each, that would cost $52 for one yard.
  • ​Quality - not even close
    • Read the comments on the big box store websites - trash in mulch, inconsistent color and texture between bags, dye that stained driveways, unknown tree species, and unknown sources.
    • We offer only chemical-free all natural products (from Maine whenever possible) and offer a range of prices and colors to meet your budget and your taste.
  • ​​Customer Service - you decide
    • ​We stand by our products because we invest so much time finding the highest quality, all-natural Maine products.  If we wouldn't put it in our own gardens, we won't sell it to you.  It's that simple.
    • Delivery:  We can bring you as little as half a yard and drop deliver in your driveway or on your lawn.
