Propagation of Clerodendrum thomasii Moldenke
Propagation is the process of creating new plants from existing ones. Clerodendrum thomasii Moldenke, commonly known as "Bleeding Heart Vine", can be propagated through various methods, including seeds, stem cuttings, and layering.
Seeds
Clerodendrum thomasii Moldenke can be propagated by seeds. The seeds should be collected from the mature fruit, cleaned, and then sown in a well-prepared seed bed. The seed bed should be kept moist and in a shaded location until the seedlings emerge. The seedlings can then be transplanted into individual pots or directly into the ground.
Stem Cuttings
Stem cuttings is another method of Clerodendrum thomasii Moldenke propagation. Stem cuttings should be taken from the current season's growth, and the cuttings should have 2-3 nodes. The cuttings should be dipped in rooting hormone and then inserted into well-drained potting soil. The cuttings should be kept moist and in a shaded area until they develop roots and new growth. Once the new growth has emerged, the cuttings can then be transplanted into individual pots or directly into the ground.
Layering
Layering is a propagation method that involves the formation of new roots on an existing branch while it is still attached to the parent plant. For Clerodendrum thomasii Moldenke, the layering method can be done by bending a lower branch to the ground, wounding a section of the stem, and then covering the wound with soil. The covered section should be kept moist and in a shaded area. Once roots and new growth have developed, the rooted section can then be separated from the parent plant.
