About this calculator
Overview
The Mulch Calculator helps you determine the exact amount of mulch required for your garden beds. Proper mulching suppresses weeds, retains soil moisture, and improves the aesthetic appeal of your landscaping. Most garden stores sell mulch by the bag (usually 2 cubic feet or 50 liters) or in bulk.

Pro Tips
Avoid 'mulch volcanoes'—piling mulch against tree trunks—as this can lead to rot and disease.
Recommended: 2-4 inches for most garden beds.
For steep slopes, use a heavier wood chip or shredded bark mulch that is less likely to wash away.

Fun Facts
"Mulch can reduce water evaporation from the soil by as much as 35% to 50%."
"The word "mulch" likely comes from the Middle English word "molsh," which means soft or moist."
"Organic mulches, like bark or wood chips, gradually improve soil structure as they decompose."
Formula: Volume = Area (sq ft) × (Depth in / 12) / 27 (cu yd)
