This clear pod allows new roots to grow prior to taking a cutting. It allows you to see the fresh root growth without disturbing them.
The pods are sturdy and durable enough to be reused over and over again.
Your plant will need a fairly straight area of stem for the pod to fit well. Then simply fill with moss and click shut. A small cut will be made in the stem by the tabs. This will be where the cutting is taken in the future.
If you find the parent plant stem is not strong enough, the pod can be attached to a plant support or cane with a small tie.
