Frequently asked questions
- How much mulch do I need?
- Multiply the bed area (ft²) by depth (in inches ÷ 12) to get cubic feet. Divide by 27 for cubic yards. A standard bag holds 2 cubic feet.
- How deep should mulch be?
- Apply 2–3 inches for most garden beds. Avoid piling mulch against plant stems (volcano mulching), which can cause rot.
