Topsoil is one of the most commonly used materials in gardening and landscaping projects. It forms the upper layer of soil where plants grow and plays a key role in drainage, root development and nutrient retention.

This guide explains what topsoil is, how it differs from general soil, where it is used, and how to choose the right type before browsing specific soil and topsoil products.

What is topsoil?

Topsoil is the uppermost layer of soil, typically the top 150–300mm of the ground. It contains organic matter, minerals and microorganisms that support healthy plant growth.

Good quality topsoil has a balanced structure. It allows water to drain while still retaining enough moisture for roots, making it suitable for lawns, planting and landscaping work.

Topsoil vs general soil

The term “soil” is often used broadly, but not all soil is suitable for planting.
General soil may include subsoil, clay-heavy material or excavated ground that lacks the structure and organic content needed for healthy growth. Topsoil is selected and prepared specifically for growing purposes.

Using topsoil rather than general soil helps improve drainage, aeration and root development, particularly in new or reworked areas.

Common uses of topsoil

Topsoil is used across a wide range of domestic and landscaping projects.

Lawns

Topsoil is commonly used to level ground before seeding or laying turf. It creates a consistent surface and supports even grass growth.

Turfing

A suitable layer of topsoil beneath turf helps roots establish more quickly and improves long-term lawn health.

Borders and planting

Topsoil improves soil structure in borders, beds and planters, making it easier for plants to establish and grow.

Landscaping projects

In larger landscaping schemes, topsoil is often used to reshape ground levels, prepare planting areas or improve poor existing soil.

Topsoil for lawns vs topsoil for gardens

While the same material may be used, priorities can differ depending on the application.

For lawns and turfing, a finer, more consistent topsoil helps create a smooth surface and supports even grass growth.

For gardens and planting areas, structure and organic content are often more important, helping roots spread and retain moisture.

Understanding the end use helps determine which type of topsoil is most suitable.

Types of topsoil

Different types of topsoil are available depending on how they have been processed and blended.

Screened topsoil

Screened topsoil has been processed to remove larger stones and debris. This creates a finer, more even material that is easier to spread and level, making it suitable for lawns, turfing and general landscaping.

Blended or general-purpose topsoil

Blended topsoil combines soil with organic matter to create a balanced growing medium. It is often used in borders and planting areas where nutrient content and soil structure matter more than surface finish.

Choosing the right type depends on the project and the finish required.

How much topsoil do you need?

The amount of topsoil required depends on the area being covered and the depth needed.

Lawns and turfing projects usually require a shallower layer, while borders and raised planting areas often need more depth. Topsoil is typically spread evenly to create a consistent base for planting or turf.

For more specific guidance, individual topsoil products provide information on typical coverage.

Delivery and collection considerations

Topsoil can be supplied for delivery or collected, depending on project size and access.

Delivery is often used for larger landscaping projects or where significant quantities are required. Collection can be suitable for smaller jobs where access allows.

Before delivery, it is worth considering where the soil will be placed and whether access is suitable for the chosen method.
