Dendrobium phalaenopsis problems — and how to fix them
Dendrobium phalaenopsis (Dendrobium phalaenopsis) 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 flowering
Most often insufficient light. Phalaenopsis-type Dendrobiums need brighter light than typical houseplants; move to a brighter spot and ensure steady feeding and a slight day-night temperature drop to trigger spikes.
Yellowing or dropping lower leaves
Some leaf loss on old canes is natural for this type. Widespread yellowing usually points to overwatering and root rot — check for soft brown roots and repot into fresh open bark if needed.
Shrivelled pseudobulbs
Wrinkled canes indicate underwatering or damaged roots that can't take up water. Increase humidity and watering frequency, and inspect the root system, repotting if roots have rotted.
Bud blast
Buds yellowing and dropping before opening stems from sudden environmental change — draughts, temperature swings, dry air or relocation. Keep conditions stable while in spike.
