Perlite is a naturally occurring volcanic rock, which is fired in furnaces to produce lightweight porous cinders. It is exemplary for increasing aeration in compost/soil an also excellent for moisture retention and drainage.


By mixing the fine lightweight particles with your soil/compost, you will benefit from:
  • Improved drainage and aeration.
  • Increase of water retention and absorption.
  • Stimulated growth of health, strong roots.

How to use perlite

To minimise dust when using, we recommend dampening the perlite initially. As a rough guide, if using the full bag, add approximately 1 litre of water into the bag and allow to sit for several minutes to permit soakage.

Rooting cuttings

For leaf cuttings and soft stem plants: use an equal mixture by volume of perlite with compost.

For harder cuttings and more fragile plants: use 2 parts perlite to 1 parts compost.

Keep well watered ensuring that the pot can drain well at all times. Once roots begin to appear, pot-on into compost, or a compost/perlite mix. Adding perlite at this stage will help to speed up further rooting and also greatly reduces any risk of root disease.
