Propagation of Othonna hederifolia B.Nord.
Othonna hederifolia B.Nord. can be propagated through both seed and vegetative methods.
Seed Propagation
The plant produces small, elongated seeds that can be sown directly into the soil. The best time to sow the seeds is in the spring or early summer when the soil has warmed up. Before sowing, prepare the soil by removing any weeds or debris and loosening the soil. Sow the seeds no deeper than ¼ inch and water gently. Keep the soil moist until the seeds germinate, which can take up to two weeks.
Vegetative Propagation
Othonna hederifolia B.Nord. can be easily propagated through stem cuttings. Take a cutting of about 4-6 inches long from a healthy plant and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a well-draining soil mixture. Water the cutting and cover it with a plastic bag or dome to retain moisture. Keep the cutting in bright but indirect light and ensure the soil remains moist until it develops roots. This should take around four to six weeks.
Another vegetative propagation method is through division. This can be done by carefully digging up and separating the root system of a mature plant, and planting the divisions in new pots or locations. Divisions should be kept watered until they have established their own root systems.
