Rooting a Cutting in Perlite

If you're intrigued by the idea of propagating a cutting in perlite, you're not alone. Similarly to rooting a plant in sphagnum moss, all you need to do is find a suitable pot and fill it near to the top with the perlite. We recommend using an Orchid container with drainage for the best results. Simply pour water through the perlite for 8 seconds and place your cutting's base in the middle. Wrap some cling film around the top of the pot to create a lid-effect, keeping the cuttings foliage above the film to breathe. This will lock in the humidity and allow light to penetrate the pot, thus creating the optimal condition to develop roots. Keep in a bright indirect location and on a drip-tray; water if necessary by taking off the cling film to pour water through the perlite.

Once the roots are a few inches in length, you can safely repot it into our Houseplant Potting Mix with a new pot to continue growth as a normal plant. The perlite can be used to root another cutting if it's still crunchy and healthy!
