Kanuma Soil

Kanuma soil is a granular clay-like mineral used mainly as soil for bonsai trees. It is a baked substrate obtained from the Kanuma region in Japan, which is a volcanic rock that is mined from the soil and then carefully processed, sterilized, and baked. Kanuma soil is small particles of eroded rock and does not contain organic materials. It acts as an excellent substrate for growing plants that love to thrive under slightly acidic conditions.
