Troubleshooting
Showy Corytoplectus problems — and how to fix them
Showy Corytoplectus (Corytoplectus speciosus) 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.
Leaf edge browning
Almost always caused by low humidity or cold draughts. Raise ambient humidity above 65% and keep the plant away from air-conditioning vents and cold windows.
Root rot
Overwatering in a dense mix causes basal stem collapse. Always use a well-aerated substrate and ensure the pot has drainage holes. Remove affected roots and repot into fresh mix.
Failure to flower
Insufficient light or excess nitrogen prevents blooming. Move to brighter indirect light, switch to a phosphorus-rich fertiliser in late summer, and ensure a slight cool period (16–18°C nights) to trigger bud set.
