Troubleshooting
Strongly-Scented Bulbophyllum problems — and how to fix them
Strongly-Scented Bulbophyllum (Bulbophyllum graveolens) 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.
Rhizome rot at pseudobulb base
The creeping rhizome can rot at points where it contacts constantly wet medium or standing water. Elevate the rhizome slightly above the medium surface and ensure rapid drainage. Trim rotted sections back to clean tissue and dust with sulphur or cinnamon powder.
Failure to bloom in cultivation
Bulbophyllum graveolens requires stable warmth, high light, and high humidity to trigger flowering. Temperatures below 18°C or dry conditions inhibit flowering. Some growers report that a brief (2–3 week) slight temperature drop of 3–5°C at night in autumn can stimulate spike initiation.
Fungal root rot from poor drainage
The preference for consistent moisture creates a fine line with overwatering. A heavy or decomposed medium that holds water can cause Phytophthora or Fusarium root rot. Refresh the medium annually if it begins to compact, and always use a container with ample drainage.

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