Noble Dendrobium (miniature form) problems — and how to fix them
Noble Dendrobium (miniature form) (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.
Failure to bloom
Usually caused by omitting the cool dry winter rest. Cool nights (8-13°C) and minimal watering for 6-8 weeks are essential triggers.
Keiki formation instead of flowers
Excess nitrogen in late summer can stimulate plantlets rather than flowers. Switch to a low-nitrogen, high-potassium feed from August.
Cane rot
Overwatering or water pooling in leaf axils. Ensure fast-draining medium and avoid wetting canes.
Shrivelled canes
Indicates underwatering or root loss. Inspect roots; increase watering cautiously during growing season.
Scale insects
Appear as brown bumps on canes. Wipe away with a damp cloth or treat with horticultural oil.
