How to Calculate Mulch Coverage
Formula
Mulch suppresses weeds, retains moisture, and insulates plant roots. Knowing the right amount to order saves money and multiple trips to the garden center.
The ideal mulch depth is 2 to 4 inches for most flower beds and landscaping. Deeper layers can suffocate roots and harbor pests.
Common use cases:
- Flower bed and garden mulching
- Tree ring coverage
- Playground surfacing
