Frequently Asked Questions
How deep should mulch be?
A 2 to 4 inch layer is ideal for most landscaping. Too little mulch allows weeds through; too much can suffocate plant roots.
How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard. Cubic yards are the standard unit for bulk mulch delivery.
Should I buy bags or bulk mulch?
For small projects under 2 cubic yards, bagged mulch is convenient. For larger areas, bulk delivery is usually more cost-effective.
Does mulch settle over time?
Yes, organic mulch can settle and decompose, reducing volume by 10-20% over a season. It is common to add a fresh top-up annually.
