Troubleshooting
Coelogyne nitida problems — and how to fix them
Coelogyne nitida (Coelogyne nitida) 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 flower
Almost always too warm in winter. This species needs a distinctly cooler, drier rest (down toward 10-12°C nights) to initiate spikes; uniform warm conditions give lush growth but no blooms.
Black leaf spotting
Cool, damp, stagnant air invites fungal/bacterial spotting on the soft leaves. Increase air movement, avoid wetting foliage late in the day, and remove affected tissue with a sterile blade.
Shrivelled pseudobulbs
Indicates dehydration or dead roots from earlier overwatering. Check the root system; rehydrate gradually and increase humidity rather than drowning the medium.
Root rot
Dense, water-retentive or decomposed medium suffocates roots. Repot into fresh, chunky bark the moment the mix breaks down and never let the pot stand in water.
