Finding the right topsoil is crucial to the health, functionality, and look of your garden. At it’s most basic level, topsoil is the top layer of soil, and contains the nutrients that all plants need to grow and survive. Though the specific blends of topsoil vary depending the plants they are nourishing, just about every topsoil layer is 5 to 12 inches deep, with a calculated mixture of clay, silt and sand to provide plants with the proper growing and nutrient-receiving facilities. We at Asphalt Materials understand the necessity of ingredients and custom blends that contribute to a good topsoil and a rich, healthy garden.
