Mulch coverage and bags
Estimate mulch quantity after excluding areas you will leave uncovered.
How it is calculated
Covered area = max(0, total − excluded). Liters = covered area × depth in cm × 10. Bags = round up(liters ÷ bag liters).
Assumptions & limits
Coverage is uniform and material does not compress. Choose mulch, depth and plant clearance using local horticultural guidance. Defaults are illustrative planning inputs, not recommended minimums or a guarantee of safety.
