Topsoil is the upper, outermost layer of soil. It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs. Having a healthy topsoil is key to ensuring your plants flourish.
Any garden is only as good as its soil. If your garden is susceptible to extreme weather or is particularly sandy, clay-rich or lacking in nutrients,the solution can be found in adding quality soil and compost.
Soil can have different levels of pH values which can affect the growth of grass as well as plants. Make sure that you use the right lawn soil to give your grass the best chance of growing lush and even.
