How to use medium akadama

This is the most widely used grade. For deciduous trees it can be used on its own or with 20–30 % pumice. For conifers many people mix it with kiryu or lava so the mix drains faster and dries out more between waterings.

Good to know about akadama

  • Akadama holds water and nutrients and releases them again, while the grains still let air through.
  • The colour changes from dark to light as it dries – an easy sign that it is time to water.
  • Sieve off the dust before use so it does not block the drainage.
  • The grains slowly break down over 2–3 years – a natural sign that the tree will soon need repotting.
