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.
Scale and mealybug
Common pests on Coelogyne; inspect the pseudobulb bases and leaf axils. Treat with isopropyl alcohol on a swab for isolated infestations or systemic insecticide for severe cases.
Overwatering in winter
The most frequent error; soggy bark during the cool rest causes root and pseudobulb rot. The medium should be barely moist, not wet.
Brown leaf tips
Caused by low humidity, fluoride in tap water, or root damage. Switch to rainwater and increase humidity. Trim brown tips with clean scissors.
No flowers
This species needs a temperature drop to 8-12°C at night for 6-8 weeks in winter to set buds. Without this cool rest, vegetative growth continues but flowering is suppressed.
