Troubleshooting
Nobile Dendrobium problems — and how to fix them
Nobile Dendrobium (Dendrobium nobile) 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.
No flowers, only keikis
The classic D. nobile failure: without a cool, dry, bright winter rest and a stop to nitrogen feeding, the plant makes plantlets (keikis) along the canes instead of flower buds.
Leaf drop
Some leaf loss in autumn-winter is natural for this deciduous species. Sudden whole-cane leaf loss in summer, however, points to overwatering, cold, or root rot.
Shriveled, wrinkled canes
Underwatering during growth or, conversely, dead roots from past rot. Check roots; if healthy, water more in the growing season while keeping the winter rest lean.
Soft, rotting base
Overwatering, especially during the winter rest or in too-large a pot, rots the cane bases. Use a snug pot, sharp drainage, and keep nearly dry in winter.

Most nobile dendrobium issues are care-mismatch, not bad luck. Dial in the basics:
