Propagation of Dolichandrone (Frenzl) Seem.
Propagating Dolichandrone (Frenzl) Seem. can be done by various methods, including:
Seed Propagation
Seeds collected from the plant should be sown in well-draining soil that is moist but not waterlogged. Plant the seeds in a container with a depth of at least 10 cm. Cover the seeds with a thin layer of soil and water. Keep the soil moist and in a warm, sunny location. Germination can be seen within two weeks.
Cutting Propagation
This plant can also be propagated through cuttings. Take a cutting of 4-5 inches long from the mother plant. Remove leaves from the lower half of the stem as well as any flowers or buds. Dip the cut end of the stem into rooting hormone and plant it in moist, well-draining soil. Keep the cutting in a warm, bright location, and maintain moisture levels in the soil. Roots can start growing in a few weeks, and the plant will start growing within 4-6 weeks.
Air Layering
Air layering is another propagation method for Dolichandrone (Frenzl) Seem. Choose a lower branch from the parent plant. Create a 1-2 cm cut on the branch and dust some rooting hormone on the wound. Wrap moist sphagnum moss and plastic wrap around the cut, keeping it in place with a string. Within 6-8 weeks, roots will start to develop and the new plant can be separated from the parent plant, and planted in a new container with well-draining soil.
