Akadama is now on sale in our webstore. Mirai is proud to provide the opportunity to access this incredible soil substrate to maximize the cultivation of your finest shohin bonsai. Our limited supply of chumei, or smaller-sized akadama, is largely regarded as the highest quality in the world. It is this quality that facilitates the healthiest amount of root growth—allowing the root system to scale with the active decomposition and fracturing of the soil particles. The self-scaling nature of this material provides the best balance of water and oxygen as well as the ability to hold nutrition in the bonsai container. Take your shohin to a new level of refinement and shop now at https://goods.bonsaimirai.com/collections/supplies/products/akadama #akadama #bonsai
