Propagation of Bulbophyllum oxychilum Schltr. var. oxychilum
Bulbophyllum oxychilum Schltr. var. oxychilum is commonly propagated by two methods, namely:
1. Division
Division is the most common method of propagating Bulbophyllum oxychilum Schltr. var. oxychilum. The plant is divided during repotting. The best time to divide Bulbophyllum oxychilum Schltr. var. oxychilum is just before the plant enters a new growth cycle. The division should have adequate roots and pseudobulbs with at least one growth. The sections should be disinfected with a fungicide before potting. The new pots should be filled with a well-draining medium such as orchid bark, sphagnum moss, or a combination of both. The plant should be placed in bright, indirect light, and watered sparingly at first until new growth appears.
2. Seed Propagation
Propagation of Bulbophyllum oxychilum Schltr. var. oxychilum can also be achieved through seed propagation. The seeds should be collected when the seed capsule is mature and fully dried out. The seeds should be sown immediately on a sterile, well-drained medium such as sphagnum moss or fine orchid bark. The pots should be covered with either a clear plastic lid or placed in a plastic bag to increase humidity. The seeds should be kept warm, with temperatures around 77°F, and placed in bright, indirect light. The seedlings can be transplanted when they have grown 1 to 2 inches tall and developed 2 to 3 leaves. The plant should be given adequate time to establish before repotting again.
