    When it comes to cubic yards, cubic feet, etc I have not the faintest idea of how much those numbers actually come out to when trying to figure out how much mulch I might need when we buy it in bulk as I hope to do next month.
    I found this little bit of info that might clear up some confusion for some of us.

    * 1 cubic yard @ 4" thick covers 81 square feet
    * 1 cubic yard @ 3" thick covers 108 square feet
    * 1 cubic yard @ 2" thick covers 162 square feet

    Sorry, you metric users will have to convert for yourselves, my brain can't handle that right now ;)

    That sounds pretty accurate! The way my boss taught me many moons ago, is to measure the square footage (I use a measuring wheel) and then divide that number by 100 to get the number of yards needed to cover with a 3 inch layer. I've done it for so long now, I'm pretty good at "guestimating" when I eyeball a new job. It's never exact, unless the space is a square or rectangle with straight edges... doesn't happen that way very often!
    I love mulch, and love the way it dresses up a garden.

    Thanks Toni and Kay for the information. I too have been thinking of getting a truckload of mulch and didn't have a clue of how much I would need.

    Adding my thanks for the information! I may have to drive 50 miles to get a load of mulch, but at the rate I'm going with the gardens, it will be worth it. I'll get the loader to tell me how many cubic yards/feet I'm getting, so I'll know how much ground I can cover.
    Without you folks, I'd have no clue (well, I'm generally clueless but right now we are talking clueless about mulch amounts.)

    *Mulch* means different things to different gardeners.

    An arborist is going to want (and need) chipped or shredded bark mulch. Likewise a flower gardener might make use of bark mulch.

    A vegetable gardener might want autumnal leaves and grass clippings for mulch.

    For me this has meant a slow drive on trash day to look for (and steal) bags of leaves.
