premium Japanese Soil

Kanuma Soil (1–3mm, 6–6mm, 6–9mm) is a lightweight, acidic Japanese substrate designed specifically for species that thrive in lower pH conditions. Its soft, porous structure retains moisture while allowing excess water to drain freely, creating a balanced environment for sensitive roots. Naturally low in nutrients and organic matter, it gives growers full control over feeding while enhancing both root health and overall bonsai presentation.
