White and Spafford show Lamp'l around the garden's propagation facilities. They have a variety of methods for propagating plants, including stem cuttings, leaf cuttings, and seed starting. They also have specialized facilities for tissue culture, which allows them to propagate plants in sterile conditions.

Lamp'l learns about stem cutting propagation from Spafford. She explains how to take a stem cutting from a plant and create a new plant from it. She also shows Lamp'l how to create a rooting hormone from willow branches, which can help improve the success rate of stem cuttings.

Next, Lamp'l learns about seed starting from White. He shows Lamp'l the garden's seed starting facilities and explains how to start seeds indoors. White emphasizes the importance of using high-quality seed starting mix and sterilizing the containers to prevent disease.

Finally, Lamp'l learns about leaf cutting propagation from Spafford. She shows him how to take a leaf cutting from a plant and create a new plant from it. She also explains the importance of using a sterile cutting tool and keeping the cuttings in a high humidity environment.

Throughout the episode, Lamp'l emphasizes the importance of propagating plants sustainably. He discusses how to avoid taking too many cuttings from a single plant and how to avoid contributing to wild plant populations being over-harvested.

The episode concludes with Lamp'l visiting a local nursery that specializes in sustainable and native plants. He discusses the importance of supporting local nurseries and buying plants that are grown sustainably.

Overall, this episode of Growing a Greener World provides a comprehensive overview of propagation techniques for plants.
