- Cuttings: Cuttings are another common method used to propagate Scaevola chamissoniana Gaud. var. piccoi O. & I. Deg. Cuttings are taken from the parent plant and treated with rooting hormone. The cuttings are then planted in a well-drained medium and kept in a warm and humid environment. The cuttings usually develop roots within 2-4 weeks and can be transplanted to individual pots or the field after they develop a few leaves.
- Division: Division is a method used to propagate mature plants. The plant is carefully dug up, and the root ball is divided into several sections. Each section is then planted in a well-drained medium and kept in a warm and humid environment. The plants usually establish root systems within 2-4 weeks and can be transplanted to individual pots or the field.
Overall, these methods, when done correctly, can be quite effective in propagating Scaevola chamissoniana Gaud. var. piccoi O. & I. Deg. However, it is essential to ensure that the propagation is done in suitable conditions to ensure successful establishment and growth of the plants.
