Troubleshooting
Calathea Exotica problems — and how to fix them
Calathea Exotica (Goeppertia roseopicta 'Exotica') 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.
Brown, crisping leaf edges
The classic roseopicta complaint, caused by low humidity or tap-water minerals. Raise humidity above 60% and use filtered, distilled, or rainwater.
Faded painted markings
Excess direct light bleaches the rose tones; too little light dulls them. Keep in bright indirect light.
Curling, drooping leaves
Indicates underwatering or dry air; persistently wet roots instead point to rot. Maintain even moisture and good drainage.
Spider mites
Dry air invites mites on the broad leaf undersides. Boost humidity, wipe leaves, and treat promptly with neem or insecticidal soap.
