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 LECAit 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.
Do not mix Akadama with organic material.
- This fine (1~3mm) particle size akadama is suited to shohin and general bonsai growing mixes as a top dressing to encourage fine surface rooting.
- Akadama can be combined with other elements such as crushed stone or for best effect use pumice.
For typical growing conditions, a ratio of 1(akadama) : 1(pumice) can be used. For plants which prefer more moisture you can double the quantity of akadama.
