Find out how much coverage you need with the calculator below.
Coverage using mulch. We recommend a depth of 2 inches. To allow for oxygen movement, don't exceed a 2-3 inch depth for fine mulches. For coarser mulches, such as bark chips, you can lay a maximum of 6 inches.
- Coverage using gravel. Larger gravels are not as efficient in ground coverage as smaller gravels and mulch. Therefore, when using larger gravel, we recommend 30% more than what the calculator below will estimate. To account for an additional 30%, enter your measurements in the calculator. Click the Calculate button, and multiply the result by 1.3.
Of course, you're welcome to contact us to get specific coverage amounts for each type of gravel or mulch.
