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 love using this product, it helps the strength off roots and forming of roots. Also creates a nice air flow for the roots to breath.
never disappointed with the growing media from bonsaitree. quick delivery & nice to be able to source so easily from them & well priced
Love it I mixed it with Bonsai tree's professional growing mix finally got the right Bonsai soil for my trees
It is a very good product but in my climate in Kimberley it dries out very quickly and additional compost needs to be added to retain a bit more water.
I switched to using akadama over the past three years and have seen real benefits in its use. With the Kobayashi brand, the extra you get in each pack let's you mix perfect proportions of pummice and akadama without having left over pummice. Really happy with product.
