Vegetative propagation
Vegetative propagation involves multiplying plants using asexually reproduced plant parts, such as roots, stems, or leaves. Some of the commonly practiced vegetative propagation methods include:
- Division: This involves dividing the plant's rhizomes during the growing season, being careful to discolor and trim off any dead roots. The divided sections should have strong, healthy roots and stems.
- Cuttings: Select a stem from the parent plant and cut it at an angle just below a node. Place the stem in a pot or tray filled with moist soil. Cover the cuttings with a plastic bag and place them in a shaded area with a temperature of about 70 degrees Fahrenheit. Once rooted, transplant the cuttings into a larger container or back into the garden.
Following the above propagation methods, you can successfully multiply Berula Bess. ex W.D.J. Koch plants. It is essential to provide the necessary care to the plants as they take time to grow to maturity.
