Akadama is a granular volcanic clay-like (although it is not clay) mineral which occurs naturally in Japan. It has been extensively used in Japan for many years as a growing medium for bonsai trees and other container-grown plants. 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.

    I have been experimenting with different combinations & mixes to improve rooting of Asclepiads. The Akadama is a useful addition and definitely something I would advise others to try.
