Propagation of Clerodendrum trichotomum Thunb. var. ferrugineum Nakai
Propagation is the process of reproducing plants either sexually or asexually. The propagation of Clerodendrum trichotomum Thunb. var. ferrugineum Nakai can be achieved through both sexual and asexual means.
Propagation through seeds
Clerodendrum trichotomum Thunb. var. ferrugineum Nakai can be propagated through seeds. The seeds must be collected from ripe berries as soon as they fall from the plant. The outer fleshy layer should be removed, and the seeds should be cleaned. After cleaning, the seeds should be soaked in water for 24 to 48 hours to enhance their germination rate. The seeds should then be sown in well-draining soil and covered slightly with soil. The soil must be kept moist, and the seeds should take about 3-4 weeks to germinate.
Propagation through stem cuttings
Clerodendrum trichotomum Thunb. var. ferrugineum Nakai can also be propagated through stem cuttings. Cuttings should be collected from the parent plant and treated with a rooting hormone to stimulate root growth. Cuttings without leaves are preferred. The cuttings should be placed in well-draining soil and kept slightly moist. In about 4-6 weeks, roots should begin to form.
Propagation through layering
Clerodendrum trichotomum Thunb. var. ferrugineum Nakai can also be propagated through layering. In this method, a low-lying branch of the parent plant is bent down to the ground. The bark on the underside of the branch should be scraped to promote root growth. The branch should then be pinned to the ground with a small stake and covered with soil. After about 2-3 months, roots should have formed, and the new plant can be separated from the parent plant.
