Bantam soil is the fundamental core of every potting mix. Simply add the necessary nutrients and/or fertilizer of your preference. These soils are vital for retaining an adequate balance of oxygen/moisture around roots and absorbing excess liquids reducing over-watering. Outline or enhance the aesthetics of models, hardscapes, or other top-layer decorations. Bantam soil can also be used as a growing medium for many plants as well as make a solid surface for moss to establish.
