    Wondering if anyone has this figured out...

    If an existing area is 109' in total diameter and its has 24 Azaleas (small), 11 Liropetalum, 6 Iris' and about 30 variegated liriope, all young shrubs, how do you determine the true amount of mulch to use at 1-2 inches?

    I came up with a straight 28 cu/yards @ 1" and 56" @ 2

    Any thoughts are most welcomed.

    Thank you for your time.

    Measure their approximate diameter, then you can figure out how many square feet they take up and from there you can figure out how many square yards they take up and subtract that from your total yards. I do it all in an excel program I designed, it figures this stuff out in a matter of seconds.

    Take a guess.

    It should be relatively easy to guess withing 10%.

    The area is such and such size - the plants cover 45% of it.

    I usually estimate slightly high and use the extra on another part of the property, or take a little bit back home.
