Troubleshooting
Christmas Orchid problems — and how to fix them
Christmas Orchid (Cattleya trianaei) 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
Insufficient light is the primary cause; secondary causes include skipping the autumn dry-down rest.
Root rot
Decomposed bark retaining moisture suffocates roots; repot into fresh coarse mix every 2-3 years.
Scale insects
Armoured scale on pseudobulbs and leaf undersides is common, especially in still indoor air.
Bud blast
Ethylene from ripening fruit, gas stoves, or draughts causes developing buds to brown and drop.
Viral mosaic on leaves
Cattleyas are susceptible to Cymbidium mosaic virus (CymMV); introduced on contaminated cutting tools — sterilise tools between plants.
