Propagation of Clerodendrum Silvestre B. Thomas
Clerodendrum silvestre B. Thomas is primarily propagated through stem cuttings and seeds.
Propagation through Stem Cuttings
Stem cuttings from the plant should be taken during the growing season, typically during the spring or summer. Cuttings should be taken from healthy stems with a diameter of around 0.5 to 1 cm. The cuttings should be around 10-15 cm in length and should be taken from the upper part of the plant.
After taking the cuttings, remove the lower leaves and any flowers or buds. Dip the cut end into a rooting hormone and plant it in a well-draining soil mix. Water the soil and place the container in a warm, humid location with bright but indirect sunlight.
The cuttings should develop roots within 3-4 weeks. Once the roots appear, transplant the cutting into a larger container or into a garden bed.
Propagation through Seeds
Seeds from Clerodendrum silvestre B. Thomas are viable and can be used to propagate the plant. The seeds should be sown in a well-draining soil mix, either directly in a garden bed or in a container.
