❓ Common questions
- How deep should I apply mulch?
- 2–3 inches is ideal for most garden beds. Too shallow won't suppress weeds; too deep (over 4 inches) can suffocate plant roots and cause rot.
- How many square feet does a bag of mulch cover?
- A standard 2 cubic foot bag covers about 8 sq ft at 3 inches deep, or 12 sq ft at 2 inches deep.
- What's the difference between cubic yards and cubic feet?
- There are 27 cubic feet in one cubic yard. Bulk mulch is sold by the cubic yard; bagged mulch is sold by the cubic foot.
- Should I buy bulk or bagged mulch?
- Bulk is cheaper for large areas (over 3 cubic yards). Bags are more convenient for small projects and easier to transport in a regular vehicle.
- Do I need to remove old mulch before adding new?
- Not always. If old mulch is less than 2 inches deep and not matted, you can top-dress. Remove old mulch if it's compacted, moldy, or over 4 inches deep.
