Troubleshooting
Golden Arch Dendrobium problems — and how to fix them
Golden Arch Dendrobium (Dendrobium chrysotoxum) 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
Skipping the cool, dry winter rest is the most common cause of vegetative-only growth year after year.
Soft, sunken pseudobulbs
Indicates chronic underwatering during the growing season or root loss from rotting.
Leaf yellowing
Dropping lower leaves is normal as pseudobulbs mature, but widespread yellowing signals overwatering or root rot.
Mealybugs
White cottony clusters hide in pseudobulb sheaths, especially under warm, humid indoor conditions.
Fungal spotting on leaves
Overhead watering combined with poor airflow encourages fungal leaf spot; water at the base and increase ventilation.
