Propagation of Eulophia chilangensis Summerh.
Eulophia chilangensis Summerh. can be propagated through both sexual and asexual methods.
Sexual Propagation
The plant produces capsule fruits that contain numerous tiny seeds. These seeds can be collected and sown in a seed tray or pot. The best time for sowing is during spring or summer. Before sowing, soak the seeds in water for 24 hours to soften the seed coat. Then, prepare a well-draining potting mix and sow the seeds, covering them with a thin layer of sand. Water the soil lightly and keep it moist until germination occurs. It takes between one to two months for the seeds to germinate.
Asexual Propagation
Eulophia chilangensis Summerh. can be propagated asexually through division. This method is best done during the plant's active growth period, which is in spring or summer. Carefully dig up the plant and separate the root clumps into smaller sections. Make sure that each section has a healthy shoot and root system. Plant each section in separate pots, using a well-draining potting mix. Water the soil thoroughly and keep it moist until new growth appears.
Eulophia chilangensis Summerh. is a slow-growing plant, and it may take up to several years for the plant to reach maturity and flowering stage regardless of the propagation method used.
