High quality HARD Akadama.
Imported from Japan, this Akadama is a premium substrate. Uses as the bulk component for other substrate mixes. Akadama provides a high cation exchange for nutrient availability and water retention/availability. It acts as a surface for roots to enter and divide, creating a dense healthy root system.
For the use in any Bonsai substrate, mixed or straight.
We recommend if used straight for any high metabolising and water using species such as Leptospermum, Melaleuca, deciduous trees, Larch, Ceder, redwood, Taxodium etc.
