Propagation of Bulbophyllum Ugandae
Bulbophyllum ugandae (Rolfe) De Wild. can be propagated in various ways. The most common methods of propagation are through seeds, division of pseudobulbs, and vegetative propagation.
Propagation through Seeds
Propagation through seeds is a common method but requires careful observation and a bit of patience. The seeds must be harvested when the capsule becomes brownish-yellow and has dried up completely. The seeds should be surface sterilized to avoid any fungal or bacterial infestation. The seeds are then sown in a suitable potting mix and kept in a shaded location with high humidity. The seeds usually take a few weeks to months to germinate depending on the conditions provided.
Propagation through Division of Pseudobulbs
Bulbophyllum ugandae can also be propagated through division of pseudobulbs. The plant should be grown in a suitable medium and allowed to form a new growth. Once the new growth has reached a reasonable size, the plant should be carefully removed from its pot. The pseudobulbs should be separated gently by cutting them apart and then replanted in separate containers. Each division should have its own roots and leaves, and a layer of sphagnum moss can be used to wrap around the roots to help it establish quickly.
Vegetative Propagation
Vegetative propagation of Bulbophyllum ugandae is another popular method. In this method, new plants can be grown from stem cuttings. The stems should be cut from healthy growth and should be about 5-10 cm long. The cuttings should be rooted in a container with a suitable potting mix and kept in a warm, humid location with filtered light. With care, new growth will emerge from the cuttings in a few weeks to months.
