Akadama(赤玉土, akadamatsuchi, red ball earth) is a naturally occurring, granular clay-like mineral. Imported from Japan, it is our favourite topping stone to decorate the surface of the soil. It has good water retention properties and it drains well. It is also a great indicator of soil moisture as it is a light brown color when dry and a dark brown color when moist. Recommended for all succulent plants. It can be used for most house plants as well.
