Kanuma  Japanese Pumice 14L (3-5MM GRADE) This is similar to the Small Grade of the other brand of Kanuma we stock.

A granular Japanese potting medium for Ericaceous (Acid Loving) Bonsai. Its acidic, soft, highly water and nutrient retentive soil used primarily with Satsuki azaleas. Can be easily crushed so be careful when working with Kanuma soil around the root ball. This particular Bonsai potting mix comes from the Kanuma Area of Japan which is basically the center of Azalea Bonsai Growing. Again, you must understand as with Akadama, that Kanuma soil is the stuff that the Japanese have out in their back yards it's their "dirt." This material is dug out from 10 feet down, allowed to dry, crushed, and then sorted as to grain sizes. This Bonsai growing medium is more acidic than Akadama, and therefore, used mainly for Azaleas, Camellias, Gardenias and other acid-loving Bonsa.
