Propagation of Euphorbia celastroides Boiss. var. hanapepensis Sherff
Euphorbia celastroides Boiss. var. hanapepensis Sherff is a unique perennial plant that originates from Hawaii. The plant features glossy leaves and stunning crimson flowers that bloom annually, attracting bees and hummingbirds. If you would like to propagate Euphorbia celastroides Boiss. var. hanapepensis Sherff, utilize the following methods:
Propagation by Cuttings
Propagation by cuttings is a reliable method to grow new Euphorbia celastroides Boiss. var. hanapepensis Sherff. In this method, you can use a sharp knife or a pair of scissors to cut a healthy stem from the mother plant. When selecting cuttings, look for stems that are at least four inches long and contain two or three sets of leaves.
After taking the cuttings, place them in a dry, warm place and allow the cuttings to dry for a day or two. This process enables the wound caused by cutting to heal and prevent infection of the plant. Afterward, dip the cuttings into hormone rooting powder and plant them into suitable potting soil.
Put the pots in a shaded area and water them sparingly. Moreover, do not allow the soil to dry up. The roots will start developing in six to eight weeks, and you can transplant the plants to their permanent location after this period.
Propagation by Seedlings
Propagation by seedlings is another viable method. Begin by collecting seeds from the mother plant during the blooming season. Select mature seeds that fully ripen and collect them in a paper bag or envelope.
Next, prepare the soil by removing weeds, rocks, and debris and tilling the soil to a fine texture. Sow the seeds at a shallow depth, no more than 1/8th inch deep, and cover lightly with soil. Ensure that the soil stays moist, and the seedlings will germinate within two to three weeks. Later on, thin them out by spacing them 12 to 24 inches apart.
However, the plant propagation by seedling is a slow process compared to the propagation by cuttings. It takes a longer time to grow large plants, so expect to wait two to three years before transplanting them to their permanent location.
