Depending on the conditions of the soil in your yard, you might need a little assistance to help the plants in your garden bed grow. That’s why it’s a good idea to stock up on topsoil before starting a gardening project. The top layer of the earth contains organic matter that vegetation needs to sprout. However, some types of topsoil are more suitable for certain growing conditions than others. Below are answers to common questions to help you make the right choice. 

An Overview of Topsoil

What nutrients does topsoil add to existing soil?

Gritty to the touch, topsoil contains potassium, phosphorus, magnesium, and calcium, among other minerals. Decomposing organic matter adds nitrogen to the material. It also contains bark particles, wood ash, and lime, which increase the pH of the existing dirt.  

Does soil need to be fertilized if it's already rich?

Topsoil also contains fertilizer, which is rich in nitrogen—a chemical that helps plants produce the chlorophyll needed for photosynthesis. Fertilizer also contains phosphorus, which helps flowering plants flourish, and calcium to help vegetables stave off disease. Even if you believe your soil is already rich in these substances, it’s a good idea to conduct a soil test before each growing season and plan accordingly. Adding a layer of topsoil can make up for the nutrients the existing soil lacks.  

What are the different types of topsoil?

All topsoil contains sand, clay, and silt. How the ingredients are proportioned is what makes some products different than others. An ideal topsoil mixture contains 60% sand, 25% silt, and 15% clay. The covering is almost black in appearance and can help retain moisture to keep plants hydrated while allowing for airflow and drainage during wet weather.  

Can I use existing soil in the yard for gardening instead of topsoil?

Topsoil is engineered to have vital nutrients and organic matter the dirt in your yard might lack. That’s why it’s best to use it for gardening instead of digging up the existing earth. Adding compost to the ground and tilling it thoroughly can also ensure that your garden plants receive essential nutrients.
