Description

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.

Uses

Do not mix with organic material.

  1. This medium (5 ~ 8mm) particle size akadama is suited to large trees and for a drainage layer.
  2. 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.

    Japanese Akadama

    I use Japanese Akadama in my shrimp tanks as a secondary substrate. This safely lowers the pH of the water. I will be trying a Akadama only tank in the future and will review my 4star rating accordingly.. Very happy with the service I've received. 5 stars for that.

    Medium Ibaraki Akadama

    Bought this for my orchids, it seems to have pretty good water retention and aeration. Will be using this for my bonsai trees as well. Thank you as well for the speedy delivery and excellent service :)

    Ph buffering in shrimp tank

    I bought the courser akadama soil to use as a substrate in my shrimp tanks to buffer the ph. Works great and looks good without topping it with other substrate.
