Troubleshooting
Tiger Crow Orchid problems — and how to fix them
Tiger Crow Orchid (Oncidium tigrinum) 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.
Pleated, accordion leaves
New growth that emerges crimped signals inconsistent watering or low humidity during leaf expansion. Keep moisture and humidity steady while the new fan develops.
No flower spike
Skipped blooming usually means too little light or no cool winter rest. Brighten the position and allow a drier, cooler 2-3 month rest to trigger spikes.
Black, mushy pseudobulbs
Bacterial or fungal rot from a soggy, broken-down mix. Cut out affected tissue with a sterile blade, repot into fresh bark, and improve airflow and drainage.
Scorched or red-flushed leaves
Direct midday sun burns the foliage. Move behind a sheer curtain; a slight bronze tinge is fine but brown patches mean too much light.
