1. Soak high quality new zealand sphagnum moss.
2. Squeeze excess water so it's similar to moisture of a damp sponge.
3. Mix in perlite, pumice or lava rock. Add more perlite for cuttings that like to be drier.
4. Put the cutting in a cup and then in a high humidity bag or prop box.
5. Add water when the moss starts to dry, which is usually after a week or 2.
