What zeolite is

Zeolites are a group of porous, crystalline minerals made up mainly of silicon, aluminium and oxygen. This zeolite is sifted to 2-6mm, a particle size that blends evenly with the other substrates on the site.

Water retention

Zeolite absorbs up to 55% of its own weight in water and releases it slowly as the roots draw on it. Water held inside the particles, rather than sitting between them, keeps moisture available without waterlogging the pot, which helps prevent root rot.

Using it in a mix

Blend it through a mix alongside akadama or Sakadama, Japanese pumice and pine bark to even out how quickly the pot dries between waterings.

Which bag size

This 5 litre bag suits single repots and topping up a blend. If you are mixing soil for several trees, the 10 litre bag is the same zeolite in bulk.
