How to use kanuma

Kanuma is the classic substrate for Japanese azaleas (satsuki) and other species of the rhododendron genus that need acidic soil. For azaleas it is often used completely on its own. For other acid-loving plants you can mix it with akadama or pumice.

Good to know

  • Kanuma is softer than akadama – avoid pressing it down hard when repotting.
  • It is pale yellow and darkens when wet, so you can see when it is time to water.
  • Use it dry – the grains then keep their shape better when you fill the pot.
  • The fine grade suits small pots and young plants.
