MEASURING BARK MULCH REQUIREMENTS

Mearsure area in cubic feet. Width times length and multiply by thickness (whatever application requires, generally from 3-4 inches thick on new beds).

EXAMPLE:

A flower bed is 20 feet long by 4 feet wide and application will be 4 inches thick. (Four inches equals 1/3 of a foot).

20' long x 4' wide x .334 = approx. 27 cubic feet

BAGGED MULCH

In this case, 27 cubic feet of bark mulch is needed to cover the entired bed four inches thick. Using bags (most bags are 2.5 or 3 cubic feet) divide mulch requirements by the cubic feet per bag to get the quantity of bags needed.

EXAMPLE:

27 cubic feet needed divided by 3 cubic feet per bag equals nine bags

Area in feet to be mulched
27
=
9 bags needed to cover entire area.
Quantity per bag
3

BULK MULCH

Buying bark mulch in bulk, take the cubic feet needed to cover entire area and divide by 27. (There are 27 cubic feet in one cubic yard.)

EXAMPLE:

27 cubic feet needed divided by 27 cubic feet per cubic yard equals one cubic yard.

Area in feet to be mulched 27 = 1 yard needed to cover entire area.
Cubic feet in one cubic yard 27

PRODUCING BARK MULCH

Raw bark is gathered in the sawmill. Before a log is sawed into lumbar, it passes through a debarker which removes the bark. The bark may be passing through a hammermill or shredder.

As much as 15 percent of a tree's volume is bark. For every 1000 board feet of lumber manufactured, about 1200 pounds of green (fresh) bark is produced.
