Troubleshooting
Large-Bulb Bulbophyllum problems — and how to fix them
Large-Bulb Bulbophyllum (Bulbophyllum macrobulbon) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow or no flowering
This species requires many years to reach flowering maturity and needs consistently warm conditions. Ensure the plant has accumulated at least 6–8 healthy pseudobulbs, temperatures stay above 18°C, and light is adequate. Do not rush the plant — maturity cannot be bypassed.
Root rot from waterlogged medium
Large pseudobulbs that begin to wrinkle despite regular watering often indicate root loss from rot. Check the roots; if they are brown and soft, remove all affected tissue, dust cut surfaces with cinnamon or sulfur powder, and repot into fresh chunky medium.
Leaf tip browning
Brown leaf tips are usually caused by low humidity, fluoride in tap water, or salt build-up in the growing medium. Raise humidity above 60%, switch to rainwater, and flush the medium monthly with plain water to clear accumulated mineral salts.
