Propagation of Coleus swynnertonii S.Moore
There are several methods of propagating Coleus swynnertonii S.Moore, which is a tropical plant that belongs to the Lamiaceae family. Propagation is the process of creating new plants from existing plants. This can be done sexually or asexually.
Propagation by Seeds
Propagation by seeds is the sexual method of propagating plants. In the case of Coleus swynnertonii S.Moore, seeds should be sown in a well-draining soil mixture that has been moistened. The seeds should be placed 1/16 inch deep into the soil and covered with a thin layer of soil. The container should then be placed in a warm, bright location. The seeds will germinate in approximately 1-2 weeks. As the seedlings grow, they should be transplanted into individual pots and cared for accordingly.
Propagation by Stem Cuttings
Propagation by stem cuttings is the asexual method of propagating plants. In the case of Coleus swynnertonii S.Moore, stem cuttings should be taken from an existing plant. The stem should be cut approximately 4-6 inches from the tip. The lower leaves on the stem should be removed, leaving only a few leaves at the tip. The stem should then be inserted into a well-draining soil mixture that has been moistened, ensuring that at least one node is buried beneath the soil. The container should then be placed in a warm, bright location. The cutting should root in approximately 2-3 weeks. Once the cutting has rooted, it can be transplanted into an individual pot and cared for accordingly.
