Propagation by Seed
The most common propagation method for Stomatium deficiens is by seed. The seeds should be harvested when the fruit has ripened and turned yellow. The pulp should be removed by soaking the seeds in water for 24 hours, after which the seeds should be cleaned and dried in a shaded area. Seeds can be sown in trays filled with a well-drained soil mix and a layer of fine gravel on the bottom. They should be covered with a thin layer of soil and kept moist. Germination usually takes two to three weeks, and the seedlings should be transplanted when they reach a height of about 5 cm.
Propagation by Division
Another propagation method is by division. This is best done in early spring before new growth appears. The plant should be carefully dug up, and the roots should be gently separated to create new plants. Each new plant should have a few stems and some roots attached, and they should be planted in a well-draining soil mix. The soil should be kept moist until the new plants are established.
Propagation by Stem Cuttings
Stem cuttings can also be used to propagate Stomatium deficiens. Cuttings should be taken in the early summer when the plant is actively growing. The cutting should be at least 5 cm long and should be taken from the top of the plant. The leaves on the bottom half of the cutting should be removed, and the cutting should be allowed to dry for a few days. Once the cutting has calloused over, it can be planted in a well-draining soil mix. The cutting should be kept moist and should root within two to three weeks.
Overall, Stomatium deficiens is a relatively easy plant to propagate. By following these simple steps, gardeners can quickly and easily expand their gardens with this unique and attractive plant.
