Size:13 Liters  |  Color:25mm Grain Akadama (red ball earth) is a volcanic byproduct mined exclusively in Japan. It is similar to clay with microscopic differences that make it ideal for bonsai use. Akadama is excellent as a component in bonsai soil as it retains nutrients. It also allows roots to grow through it and breaks down over time. Akadama is a key component in nearly all quality bonsai soils. The shipping process will break down some of the akadama so it will need to be sifted prior to use. The fines in Akadama restrict aeration within bonsai soil so need to be removed prior to repotting. The fines can be saved and mixed with sphagnum moss to create muck which is commonly used in forest plantings.
