Understanding your calculation
Method, example and limitations
How the calculation works
Mulch volume equals covered area multiplied by layer depth after converting depth to the same length unit.
Example to check
An area of 100 ft² with a depth of 3 inches needs 25 ft³, or about 0.926 yd³, before allowance.
Before using the result
Settling, uneven ground, product moisture and bag volume affect ordering. Avoid excessive depth around plant stems and follow appropriate landscaping guidance.
