How much mulch
should I buy?
As a general rule of thumb, one
cubic yard of bark mulch will cover an area measuring about 100
square feet. Most landscape professionals recommend a depth of
about 3inches thick. If you’re adding a layer of top dressing
to an area that was previously mulched, you may wish to use a
little less.
How to
Measure
To calculate
the amount of mulch you’ll need, measure the length and width of
the area you wish to cover. Remember if you pace it out or use
meters, you’ll need to convert your calculations to feet.
Multiply
length x width to determine the number of square feet to be
covered.
For example,
let’s say you wish to mulch an area 100 feet long and 10 feet
wide. Multiplying the length (100 ft.) X width (10 ft), we come
up with an area measuring 1,000 square feet. Divide total square
feet (1,000) by 100 to determine the number of cubic yards of
bark mulch you’ll need to order.
The following
chart can be used to help you determine the number of yards of
bark mulch you’ll need to order.
