Troubleshooting
Fringed Coelogyne problems — and how to fix them
Fringed Coelogyne (Coelogyne fimbriata) 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.
Root loss from old bark
Fine bark decomposes faster than coarse grades and can stay wet, rotting roots. Repot every 18-24 months into fresh medium.
Spider mites
Can occur in warm, dry indoor conditions. Increase humidity and treat affected plants with neem oil or insecticidal soap spray, covering leaf undersides thoroughly.
Poor flowering
Typically caused by insufficient light or the absence of a cooler autumn period. Ensure the plant experiences a temperature differential of at least 5-8°C day-to-night in autumn.
Crown rot
Water sitting in the growth apex causes blackening and rot. Water early in the day so excess moisture evaporates, and ensure good air circulation around the plant.
