Moore's Coelogyne problems — and how to fix them
Moore's Coelogyne (Coelogyne mooreana) 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 despite healthy growth
Moore's Coelogyne requires cool nights (10–13°C) in autumn and early winter to initiate buds. Plants kept above 18°C at night year-round will produce lush foliage but no flowers. A cool windowsill or unheated greenhouse in autumn triggers reliable blooming.
Brown leaf tips
Usually caused by salt accumulation from tap water or high fertiliser concentration. Use rainwater or RO water, flush the medium with clean water monthly, and fertilise at no more than quarter-strength.
Pseudobulb yellowing
Older back-bulbs naturally yellow over time — this is normal. Premature yellowing of current pseudobulbs indicates overwatering or poor drainage. Check roots, improve drainage, and reduce watering frequency until new healthy roots are established.
