AKADAMA AND KANUMA SOILS
Our imported soils are high quality akadama and kanuma from Japan. Japan sells several grades of these soils graded by size and quality. The top layers of these volcanic soils are soft and decompose very quickly. Within a year, they can become mush in your bonsai pot.
We purchase the best grade of Japanese soils for our nursery. We learned the hard way that using poor soils that may cost less, will end up costing more in the long run. We planted hundreds of Satsuki Azaleas in inexpensive kanuma, and in less than a year they were in poor health and in need of repotting to get them out of rapidly decomposing kanuma.
