How to use coarse akadama

The coarse grade gives plenty of air around the roots in large pots, where water would otherwise stand for too long. Use it as a drainage layer at the bottom with the medium grade on top – or mix it with coarse pumice or lava for large deciduous trees.

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.
