There are many names for what is known as topsoil and it can be confusing. Some customers will ask for dirt and some will ask for topsoil when they mean potting soil. So what is top soil? Topsoil refers to native soil which is usually composed of sand, silt and clay.  In certain areas on the island of Hawai’i, a unique combination of volcanic ash deposits, lush vegetation, humidity and time have conspired to create a deep layer of topsoil rich in organic matter. At Soil Plus, our top soil is worth its weight in gold. This nutrient-rich topsoil is an ideal base to add compost and cinder, creating the perfect growing medium for plants, grass, crops and trees. Our 1/3rd Mix, CTH and Cinderless Blend are soil blends that contain top soil. If you’re looking for plain topsoil with nothing added to it, we do have this available as well. Be sure to ask for plain topsoil (also known as Cinderless without Compost) at our sales office.
