Gardening soil, also referred to as topsoil, is a natural dirt. It is found in the ground and also can be combined with various other ingredients to promote healthy plant growth. Typical blends to topsoil consist of manure and garden compost. These blends are meant to be "conditioners" to the topsoil because topsoil per say is normally not quite enough in making plants expand. It is normally for exterior plant use due to its all-natural buildings that enable healthy and balanced roots as well as eventually, allow healthy plants.
