Kanuma is a soft, pale-yellow volcanic soil from Japan, prized by bonsai growers and anyone raising acid-loving plants. Its porous, airy structure holds moisture well while still draining freely, giving roots the ideal balance of air and water.
Naturally acidic, Kanuma is the classic choice for azaleas (especially satsuki), rhododendrons and other ericaceous plants, as well as bonsai. Used on its own or blended into a mix, its small, free-draining particles encourage strong, healthy roots and help guard against waterlogging.
