Propagation of Pteronia camphorata can be done through seeds or cuttings. For seeds, they should be sown in well-drained soil during the early spring or late winters. The seedlings should be transplanted into larger containers or in the garden after 2-3 months.
If propagated through cuttings, they can be taken up during the early summer, and be planted in a container with well-drained soil and kept in a shaded area until established.
Watering needs
Proper watering is essential for the growth of the Pteronia camphorata (L.) L. var. stricta (Aiton) Harv. When planting in containers, ensure the soil is well-drained, and water until it drains out of the container bottom. In the garden, it's recommended to water the plant deeply once a week.
