Bulbophyllums are a massive, diverse genus of tropical orchids characterized by distinct pseudobulbs, single leaves, and often foul-smelling flowers. They share identical growing requirements with associated genera like Cirrhopetalum and Trias.
-
Light: Provide bright, indirect light (similar to Phalaenopsis or Cattleya conditions). Leaves should maintain a healthy apple-green color.
-
Water: Best grown mounted; require daily spraying, which can be increased to twice daily if pseudobulbs shrivel from underwatering. Reduce watering frequency in winter.
-
Humidity: Target a minimum of 50% humidity. They thrive at peak potential when a dedicated misting system is provided.
-
Temperature: Varies drastically depending on the specific species, as the genus includes varieties native to both hot lowlands and cooler mountain cloud forests.
-
Potting & Media: Ideally grown mounted on plaques or in plastic mesh boxes with very coarse media. They are fast growers that easily outgrow traditional pots.
-
Fertilizer: Apply a balanced growth fertilizer (like HighGrow) once a week throughout the year. Switch to a blooming fertilizer (like HighBloom) during their annual springtime flowering period.
