Frequently Asked Questions
What depth of mulch should I use?
A typical mulch layer is 2-4 inches deep — enough to suppress weeds and retain moisture, but not so deep that it suffocates plant roots or promotes fungal growth against stems.
How does topsoil depth differ from mulch?
Topsoil for new garden beds or lawns is often applied much deeper (4-6+ inches) since it needs to actually support root growth, unlike mulch which sits on top purely for moisture retention and weed suppression.
How many bags is a cubic yard?
A cubic yard equals roughly 13-14 standard 2-cubic-foot bags of mulch or topsoil — for small areas, comparing bagged vs. bulk delivery cost per cubic yard helps determine the more economical option.
