A lot of people want to know how to figure out the correct amount of mulch for their landscaping project. So D Felix came up with a good idea to have the formula stuck to the top of this forum.

Here it is:

To determine how much mulch is needed, you take:

Total square feet x depth desired (in feet) / 27 = cubic yards needed

Figure out your square footage.
Take square footage time depth desired (in feet, i.e. 3" = .25 feet).
That gives volume in cubic feet.
Divide that number by 27 to get cubic yards. There's 27 cubic feet per yard (3'x3'x3'=27 cubic feet).

Ok, do soil works out the same way also? Or what if your using 60 3 cubic bag of mulch. How much soil do you needed at 2" dept.
