 What is topsoil?

Topsoil is the most wonderful and precious resource on this earth. If it were not for topsoil and rainfall, life on earth would be very different indeed.

If you were to dig a very deep hole in your garden – or anywhere in fact, you’ll see that there are lots of distinct layers.

Nearest to the top is topsoil. It’s where you’ll find plant roots, mini beasts, microbes and a wealth of living things that scientists are still learning about.

Below the topsoil is subsoil. It tends to be hard to dig, a kind of a dull beigy-grey colour and not at all exciting. Its job is to supply the soil and everything living in it with minerals. It’s also extremely important for drainage.

Beneath the subsoil is the bedrock – which is, as the name suggests, pretty rocky. Bedrock determines the mineral content of the subsoil, purifies water as it drains through it and provides a firm foundation for everything above it.

The depth and the consistency of each layer varies from region to region. And indeed from garden to garden and that’s one of the reasons why certain plants grow well in some areas and not others.

What is in topsoil?

Now, that’s a very difficult question to answer because everyone’s garden is different. But in general terms, topsoil is a mix of millions of different particles.  There are sandy type particles made from minerals. Silt – miniscule particles often from ancient river mud or from dust that has settled on the surface of the earth. And clay, medium sized particles that can stick together like glue. Added to those is organinic matter. Dead vegetation and animals in various stages of decay.

If soil were a recipe, the different types of particles would be the dry ingredients and the proportions of them will determine the texture and the character of the final dish.

Topsoil with a high proportion of sand will be free draining and low in plant nutrients. It’s great for growing wildflowers but lawn turf, vegetables and/or flowers will need lots of feeding and watering

How do I judge topsoil quality?

  • Good topsoil smells “earthy” any chemical type aroma should be investigated by an expert
  • Nice brown or brown-black colour. Grey may indicate subsoil, yellowy-brown could have a high sand content
  • Bag only contains soil. No rubble, cloth, sticks, stones or plastic
  • Texture is not too crumbly, not too sticky

The first thing to judge when you are assessing soil is the smell. Soil smells like – well – dirt. It’s not an unpleasant smell, kind of like damp leaves. If you can smell poo, bleach, or any kind of chemical whiff, then the soil could be contaminated.

A nice loamy topsoil will be crumbly and sweet smelling. Choose a screened topsoil to make sure you don’t buy lots of unwanted stones or plant debris.

If you are buying soil online or over the phone, ask for reassurance that the soil has come from a reputable source and is free from contaminants.

Where Can I find reputable Topsoil suppliers near me?

A quick glance at the ads section in your local paper or an internet search will normally flag up several potential suppliers. Your job is to decide who has the right quality of soil for your project and whether or not it has been properly sourced and screened.

Never buy soil from anyone with no horticultural associations. Sometimes builders or DIY’ers will sell the soil that has been removed from a building site. Be very careful – building foundations involves removing subsoil and you definitely don’t want to be buying that.

Look for soil that will suit the project you are planning.

The ideal topsoil for gardeners is easy to work with and will grow healthy plants

For growing wildflowers, you will need a specialist soil with very low nutrient levels. Meadowmat low fertility soil has been specially blended. It drains well, is easy for you to handle and discourages excess grassiness.  Read more about low fertility soil here

For general landscaping, turf laying and growing most fruits and vegetables, this screened soil is ideal.    It’s sensibly priced, but at the same time it is free from big stones, plant debris and chemical contaminants.

For container growing, many people opt for a peat based growing medium. Peat isn’t terribly sustainable and so the Turfonline Team recommends this enriched topsoil.  You can use it for topdressing lawns too. The drainage is excellent and its bursting with nutrients. 

Worried that your soil might dry out too quickly? Rake in some of these water retaining gel crystals for extra reassurance.  They’re great for hanging baskets, small pots, raised beds and turf laying.
