FAQ
- How deep should mulch be?
- Around 50 to 75 mm is a common garden depth. The calculator uses the depth you type.
- How do I convert to bags?
- Divide the litres by the bag size. A 25 litre bag of this example is about 17 bags.
- Are the measurements in metres?
- Yes. Depth is metres too, so 70 mm is 0.07.
