Troubleshooting
Pink Rock Orchid problems — and how to fix them
Pink Rock Orchid (Dendrobium kingianum) 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
Caused by insufficient cool, dry winter rest — temperatures above 15°C at night prevent spike initiation.
Root rot
Overwatering or dense potting medium starves roots of oxygen, leading to blackened, mushy roots.
Mealybugs
Waxy white clusters in leaf axils and pseudobulb sheaths, more common in warm, still air.
Pseudobulb shrivelling
Underwatering during summer active growth causes pseudobulbs to wrinkle and deflate.
Leaf tip burn
Salt build-up from tap water or over-fertilising scorches leaf tips; flush potting medium regularly.
