Long-Flowered Bulbophyllum problems — and how to fix them
Long-Flowered Bulbophyllum (Bulbophyllum longiflorum) 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.
Root desiccation on mounts
Mounted plants in warm, airy rooms can dry out faster than roots can absorb moisture. Increase misting frequency to at least once daily in summer, or move to a shallow basket with sphagnum to retain more moisture. Monitor pseudobulb firmness as an indicator of hydration.
Rhizome rot from stagnant moisture
Dark, soft patches on the rhizome between pseudobulbs result from excess water sitting in still air. Improve air circulation with a small fan, and if potted, switch to a more open medium. Cut back to clean healthy tissue with a sterile blade and treat with a fungicide.
Restricted spread inhibiting flowering
This species needs room to creep and extend its rhizome. A crowded pot restricts pseudobulb production and reduces flowering. Remount onto a larger cork slab or transfer to a wider shallow basket when pseudobulbs reach the edge of the current mount.

Most long-flowered bulbophyllum issues are care-mismatch, not bad luck. Dial in the basics:
