The Ultimate Guide to Topsoil: Choosing the Right Topsoil for Your Garden Project

Whether you're laying a new lawn, planting a flower bed or levelling an uneven garden, choosing the right topsoil can make all the difference.

Not all topsoil is the same. Different projects require different types of soil, and selecting the right product from the start will help your garden establish more successfully.

In this guide, we'll explain what topsoil is, when you should use it and how to choose the right type for your project.


What Is Topsoil?

Topsoil is the upper layer of soil where most plant roots grow. It contains organic matter, nutrients and minerals that support healthy plant growth.

Good quality topsoil provides the ideal foundation for lawns, flower beds, borders and vegetable gardens. It can also be used to improve poor existing soil or build up areas where soil levels need raising.


When Should You Use Topsoil?

Topsoil has many uses around the garden and is one of the most versatile landscaping materials available.

You may need topsoil if you are:

• Laying new turf
• Creating flower beds or borders
• Filling raised beds
• Levelling uneven ground
• Replacing poor quality soil
• Preparing an area for planting

If the existing soil is compacted, lacking nutrients or has been disturbed during building work, adding fresh topsoil can help create better growing conditions.


How to Choose the Right Topsoil

The best topsoil depends on what you're trying to achieve.

At Springbridge Group, we supply several different topsoil products, each designed for different applications.

New Lawns

If you're laying a new lawn, your foundation is just as important as the turf itself.

Our BS3882 Multi Purpose Topsoil is screened to 10mm and blended with compost and sharp sand to create a free draining growing medium. It provides an excellent base for laying turf and establishing healthy root growth.

Planting Beds and Borders

For shrubs, flowers and general planting, our BS3882 Double Screened Multi Purpose Topsoil provides a fertile growing medium suitable for a wide range of garden projects.

Vegetable Gardens

Healthy vegetables begin with healthy soil.

Using a nutrient rich topsoil gives vegetables the best possible growing conditions and improves soil structure throughout the growing season.

Building Up Levels

If your project requires volume rather than planting quality, our Screened Economy Topsoil offers a practical solution for raising levels and general landscaping work.

It is ideal for filling and levelling but is not recommended as the final growing layer for planting or turf.


Why Does Quality Matter?

The quality of topsoil has a direct impact on how well plants establish and perform.

Buying from a reputable supplier helps ensure your topsoil is suitable for its intended use and meets recognised quality standards where applicable.

At Springbridge Group, many of our topsoil products are certified to BS3882, giving customers confidence that they are purchasing quality material suitable for landscaping applications.


How Much Topsoil Do You Need?

The amount of topsoil required depends on the size of the area and the depth you need.

As a general guide:

• New lawns typically require around 100mm of topsoil.
• Flower beds and borders often benefit from 150 to 200mm.
• Raised beds may require a greater depth depending on what you're planting.

If you're unsure, our Topsoil Calculator can help estimate how much you'll need before ordering.


Preparing the Ground

Before adding fresh topsoil:

• Remove weeds and large stones.
• Break up compacted ground.
• Level the surface.
• Spread the topsoil evenly.
• Lightly rake to create a smooth finish.

Taking time to prepare the area properly helps create better growing conditions and produces a more even finish.


Frequently Asked Questions

Can I lay turf directly onto existing soil?

If the existing soil is poor quality or compacted, adding fresh topsoil before laying turf is recommended. This provides better growing conditions and encourages stronger root establishment.

Is topsoil the same as compost?

No.

Topsoil provides the structure and growing medium for plants, while compost is primarily used to improve soil fertility and organic matter. The two products often work best when used together.

Should I buy screened topsoil?

For most garden projects, screened topsoil provides a smoother finish and is easier to spread, making it suitable for turf, planting and landscaping.


Choosing the Right Topsoil

Every garden project is different, which is why selecting the right topsoil is so important.

Whether you're laying a new lawn, creating planting beds or levelling your garden, using the correct product will help achieve better results.
