Troubleshooting
Coconut-Scented Bulbophyllum problems — and how to fix them
Coconut-Scented Bulbophyllum (Bulbophyllum cocoinum) 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.
Pseudobulb shrivelling
Shrivelled, wrinkled pseudobulbs indicate drought stress or root failure. Check roots — viable roots are white-green and firm; dead roots are brown and hollow. If roots are healthy, increase watering frequency; if lost to rot, remove affected material, treat with fungicide, and allow recovery in high humidity before resuming normal watering.
Botrytis (grey mould) on flowers
Small, grey-brown spots on flowers or buds that spread rapidly indicate Botrytis cinerea, common in cool, still, high-humidity conditions. Improve air circulation, remove affected blooms immediately, and avoid misting late in the day. A systemic fungicide can be used in persistent cases.
Slow growth or loss of fragrance
Insufficient light is the most common cause of weak growth and reduced scent production. Move the plant to a brighter (but still filtered) position. Ensure fertiliser is provided regularly during the growing season, as nutrient deficiency also reduces both growth rate and aromatic compound production.
