How to Calculate Garden Mulch

To estimate mulch, multiply your garden bed's length by its width to find the square footage. Then multiply by the thickness in inches and divide by 324 to get total cubic yards.

3 Critical DIY Mistakes to Avoid

• Over-mulching: Piling mulch too deep (more than 4 inches) suffocates plant roots and blocks water absorption.
• Mulch Volcanoes: Never pile mulch directly against tree trunks. This traps moisture and invites rot or insect damage.
• Forgetting Decomposition: Organic mulch breaks down over time. Budget for a small top-off layer every year.
