Propagation of Stoebe microphylla DC.
Stoebe microphylla DC., commonly known as creeping cotton, is a woody, perennial shrub native to South Africa. The plant is known for its delicate, cotton-like flowers and its ability to adapt to a variety of growing conditions.
There are several methods of propagating Stoebe microphylla DC., including seed propagation, vegetative propagation, and layering.
Seed Propagation
Seed propagation is relatively simple but requires patience and a good amount of time. The seeds should be collected from the plant in the dry season. They should be dried and stored in a cool, dry place until sowing.
The seeds should be sown in a prepared seedbed that is weed-free and well-drained. It is advisable to sow the seeds in the autumn season. After sowing the seeds, cover them with a thin layer of soil and water them gently. Germination will occur within 21 to 28 days.
Vegetative Propagation
Vegetative propagation methods involve taking cuttings from the parent plant and rooting them to produce new plants. The best time to take cuttings is during the spring or summer seasons when the plant is actively growing.
The cuttings should be taken from healthy, disease-free parent plants and should be approximately 5-10 cm long. The leaves at the base of the cutting should be removed, and a rooting hormone can be applied to the base of the stem to encourage root development.
The cuttings should be planted in a well-draining soil mix and kept moist until roots have formed. Once the roots have formed, the new plants can be transplanted to their desired locations.
Layering
Layering is another method of vegetative propagation that involves bending a low hanging stem down to the ground and burying a section of it in soil while it is still attached to the parent plant. The stem should be bent down in the spring season just before the plant begins to grow actively.
The section of the stem that is buried in soil should be scraped or wounded slightly and have some rooting hormone applied to it to encourage the development of roots. After a few weeks, the stem can be cut off from the parent plant, and the new rooted plant can be transplanted to its desired location.
