Find a node which you’d like to propagate from, usually four to six nodes back from the tip of the branch you’ve chosen.

With a clean knife make a few small 2mm deep incisions into the internode above your chosen node

Apply hormone

Now make sure your sphagnum moss is moist, and wrap it around the node and incisions like a sausage roll. You want it somewhat tight as the moss will loosen up when it dries.

Cover the moss with your plastic wrap a few times so it’s secure and tighten both ends with wire. Be sure to poke some holes into the moss so you can spray it with water afterward. This process only works if the sphagnum stays moist. After a few weeks you should be able to see roots growing into the sphagnum moss and this indicates you’ve successfully propagated your chosen section.

You can unwrap the plastic and make a cut below the node you’ve chosen. This cutting can now go straight into moist moss or soil, just to be sure to keep it warm and moist as it starts to establish.
