Troubleshooting
Long Spider Orchid problems — and how to fix them
Long Spider Orchid (Brassia longissima) 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.
Shrivelled pseudobulbs
Caused by insufficient humidity or underwatering. Move the plant to a more humid spot, add a pebble tray, and check watering frequency. Once pseudobulbs are firm again, the plant recovers fully.
Root rot
Overwatering or a waterlogged medium causes roots to blacken and collapse. Remove affected roots, repot into fresh bark, and reduce watering intervals. Ensure the pot has generous drainage holes.
Failure to rebloom
Brassia longissima needs a brief, cooler and drier rest period once new pseudobulbs mature. Reduce watering and lower night temperatures to around 13–15°C (55–59°F) for 4–6 weeks to initiate flower spikes.
