Propagation of Euphorbia celastroides Boiss. var. halawana Sherff
Euphorbia celastroides Boiss. var. halawana Sherff can be propagated through various methods including division, cuttings, and seeds.
Propagation through Division
Propagation through division is recommended for mature plants with a well-established root system. The best time to propagate through division is during the growing season, which is typically in the spring or early summer. Carefully dig up the plant and separate the clumps into smaller sections, each with their own roots and stems. Make sure to keep the soil intact around the roots and replant the sections in a well-draining soil mixture. Keep the soil moist until new growth appears, and then begin regular watering and fertilizing.
Propagation through Cuttings
Euphorbia celastroides Boiss. var. halawana Sherff can also be propagated through stem cuttings. The best time to take cuttings is during the growing season, which is typically in the spring or early summer. Take a 2-3 inch long cutting, making sure to make a clean cut just below a leaf node. Dip the cut end in a rooting hormone powder and plant it in a well-draining soil mixture. Keep the cutting moist and in a bright, warm location. Roots should begin to form in 2-4 weeks.
Propagation through Seeds
If you want to propagate Euphorbia celastroides Boiss. var. halawana Sherff through seeds, collect the seeds from the ripe seed capsules, which typically form in the late summer or early fall. Sow the seeds in a well-draining soil mixture and cover with a thin layer of soil. Keep the soil moist and in a bright, warm location. Seeds should germinate in 2-4 weeks.
