Soil for 10 Square Metres

Calculating Soil for a 10 Square Metre Area

Ten square metres is a common size for garden bed improvements, whether you're adding a new planting strip along a fence or topping up soil in an established bed. At 150mm depth, which is suitable for most ornamental plantings and provides adequate root zone improvement, you'll need approximately 1.5 cubic metres of topsoil to cover this area effectively.

The weight of 1.5 cubic metres of topsoil is approximately 1.65 tonnes (1,650 kilograms). This is a standard bulk delivery size that most landscape suppliers handle regularly. The soil will arrive as a single tipper load, and you'll want to have your wheelbarrow ready for distribution. At this weight, trying to carry the soil by hand from bags would require over 80 trips with 20kg bags.

Choosing the Right Depth

The 150mm depth used in this calculation suits many common garden applications. For purely ornamental plantings with shallow root systems, 100mm may suffice. For vegetable gardens or areas where you want to create good growing conditions from scratch, consider 200mm or deeper. The depth you choose directly affects the volume needed, so it's worth thinking through your specific requirements before ordering.

Topsoil Versus Specialty Mixes

Standard topsoil works well for general garden improvement and is the most economical option for larger areas. However, if you're creating new garden beds from scratch, consider whether a garden mix with added compost might be more appropriate. For vegetable gardens specifically, a premium veggie mix with higher organic content will give better results despite the higher cost per cubic metre.
