Propagation of Euphorbia celastroides Boiss. var. kealiana Sherff
Euphorbia celastroides Boiss. var. kealiana Sherff, commonly known as Hawaii Spurge, is commonly propagated through seeds and stem cuttings. The following are the propagation methods for this plant:
Propagation through Seeds
Seeds of Euphorbia celastroides Boiss. var. kealiana Sherff can be sown in a well-draining soil mix. It is recommended to scarify the seeds before sowing to improve their germination. The seeds should be lightly covered with the soil mix and kept moist until they germinate, which may take up to several weeks. Once the seedlings have grown big enough, they can be transplanted into pots or directly in the garden where they will grow.
Propagation through Stem Cuttings
Stem cuttings of Euphorbia celastroides Boiss. var. kealiana Sherff can also be used to propagate the plant. Take 6 to 8 inches of stem cuttings from healthy plants and place them in a well-draining soil mix. Make sure that the bottom portion of the cutting is buried in the soil mix. Keep the soil mix moist and place the pot in a bright, filtered light area. In approximately 2 to 3 weeks, new roots will start to emerge from the cutting. Once the cutting has rooted, it can be transplanted into a bigger pot or directly in the garden.
Care for Propagated Plants
Whether propagated through seeds or stem cuttings, caring for the newly propagated plants is essential for their survival. Ensure that the plants are placed in a bright and filtered light area and are regularly watered to maintain soil moisture. Fertilizing the plants with a balanced fertilizer every 4-6 weeks is also important to keep the plant healthy and promote growth.
