Topsoil is the top layer of soil, usually 2 to 8 inches deep, that contains most of the soil’s nutrients and fertility. If you have poor soil in your garden and want to start planting vegetables or creating a lawn, purchasing fresh topsoil will give your plants a good start.

Forming topsoil is an incredibly slow process, typically taking 100 years per inch of soil. It is formed by the weathering of rocks and the subsequent addition of organic matter from decaying plants and animals. This enriches the soil and adds important nutrients to support plant life.
