IMPORTED JAPANESE BONSAI AKADAMA - AKADAMA SMALL PARTICLE, IN SOUTH AFRICA

What is it? Akadama is a granular volcanic clay-like (although it is not clay) mineral which occurs naturally in Japan. It has been extensively used by Japanese gardeners and bonsai artists for many centuries as a growing medium for bonsai trees and other container-grown plants. It is mined from the surface of the ground, after which it is graded and packaged. Unlike LECA it is not fired at high temperatures however when it is mined from greater depths it tends to be harder or it might be slightly baked. It has many unique qualities, one of which is that when it is wet it has a darker colour so indicates when watering is needed  Akadama is unique as a growing medium and is sought after due to its ability for water retention and nutrients due to its high CEC value. However at the same time it provides porosity and free drainage. How to use? Akadama can be combined with other elements such as crushed stone, composted bark, peat, or for best effect use  pumice.
