Bonsai Soilless Potting Medium consists of organic material (such as soil conditioner or peat moss), baked or kilned clay granules (akadama is a commonly used kilned clay from Japan), and porous rock material (such as lava rock or Perma Till™). We supply our own mixture of Bonsai Soil at Randy’s Nursery. It is a great mixture for Bonsai plants formulated by our Bonsai Specialist/Enthusiast. It’s designed to decompose slowly, hold water, and provide aeration for optimum root growth and moisture retention.
