Troubleshooting
Spectacular Dendrobium problems — and how to fix them
Spectacular Dendrobium (Dendrobium spectabile) 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.
Failure to bloom
Insufficient cool, dry winter rest prevents the plant from initiating flower spikes.
Root rot
Overwatering or a dense potting mix that retains too much moisture causes roots to blacken and collapse.
Mealybugs
Soft, white cottony insects collect in pseudobulb sheaths and leaf axils, weakening the plant.
Leaf yellowing
Too little light or an interrupted growing season leads to premature yellowing and leaf drop.
Shrivelled pseudobulbs
Under-watering during active growth causes stored moisture to deplete, resulting in wrinkled canes.
