How to use 3–4 mm pumice

Mix 3–4 mm pumice with fine akadama for shohin and young trees, typically 1/3 pumice. It also works as a top layer in small pots.

Good to know

  • Pumice is the lightest type of stone and often floats on water – which makes large pots easier to move.
  • The grains hold water in their pores but drain away excess water, so the roots get air.
  • Pumice does not break down, so the mix keeps its structure for many years.
  • Rinse or sieve off the dust before use if you want the most free-draining mix.
