Propagation of Bulbophyllum calamarium Lindl. var. albociliatum Finet
Bulbophyllum calamarium Lindl. var. albociliatum Finet is a rare and exotic species of orchid that is native to Southeast Asia. Propagating this plant can be challenging, but with the proper care and techniques, it is possible to grow new plants from existing ones. Here are the different methods of propagation:
Division
Division is the easiest way to propagate Bulbophyllum calamarium Lindl. var. albociliatum Finet. This method involves dividing the plant into smaller sections, each with its roots and stem. To do this, you need to carefully remove the plant from its pot and gently separate the sections, taking care not to damage the roots. Once each section is separated, repot them into fresh orchid media and water them thoroughly. Keep them in a shaded place and avoid exposing them to direct sunlight for a few weeks until new growth appears.
Backbulb propagation
The backbulb propagation method is another way to propagate Bulbophyllum calamarium Lindl. var. albociliatum Finet. In this method, you need to separate the smaller bulbs or backbulbs from the main plant carefully. Each back bulb requires a shallow pot, and it should be planted with its top protruding from the surface. You also need to ensure that the backbulbs are not overwatered as they can easily rot if not appropriately treated. Place them in a shaded spot, avoid direct sunlight, and wait until new growth appears.
Tissue culture propagation
Tissue culture propagation is the most advanced and challenging method of propagating Bulbophyllum calamarium Lindl. var. albociliatum Finet. In this method, sterile laboratory techniques are involved, and the plant is grown in vitro on a specially formulated medium. Tissue culture propagation allows you to grow a large number of plants from a small amount of plant tissue in a sterile environment, reducing the risk of diseases and other problems. This method is quite expensive and time-consuming, and it requires specialized equipment and training.
