A Handy Guide for Gardeners, Landscapers & DIYers
Mulch is one of the simplest and most effective ways to improve your garden’s appearance and health. But when it comes time to order, many people ask the same thing: how much mulch do I need for my garden? At Kincumber Sand & Soil, we help Central Coast gardeners, landscapers, and homeowners answer this question every day.
Whether you’re refreshing garden beds or starting a landscaping project from scratch, calculating your mulch needs correctly saves time, money, and multiple trips back to the supplier.
Why Mulch Matters
Mulch offers more than just visual appeal. It plays a key role in regulating soil temperature, retaining moisture, and suppressing weeds. A properly mulched garden:
- Requires less frequent watering
- Reduces the need for chemical weed control
- Protects plant roots from temperature extremes
- Improves overall soil structure over time
And because mulch breaks down gradually, it also adds organic matter back into the soil.
How to Calculate the Right Amount of Mulch
To calculate how much mulch you need, follow this simple method:
Step 1: Measure Your Garden Area
Multiply the length and width of the area you want to mulch. For irregular-shaped gardens, break them into smaller sections and add the totals together.
Step 2: Decide on Mulch Depth
For most garden beds, 75mm (or 3 inches) is the recommended depth. For weed-prone areas, consider a thicker layer of around 100mm.
Step 3: Use the Mulch Volume Formula
Multiply the area (in square metres) by the depth (in metres). For example:
- 10m² x 0.075m = 0.75 cubic metres of mulch needed
