Troubleshooting
Calathea Medallion problems — and how to fix them
Calathea Medallion (Goeppertia roseopicta 'Medallion') 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.
Crispy brown leaf edges
Usually low humidity, or fluoride/salts in tap water. Raise humidity above 60% and switch to filtered, distilled, or rainwater.
Yellowing leaves
Most often overwatering and soggy soil. Let the top of the soil dry between waterings, ensure drainage, and reduce frequency in winter.
Curling or limp leaves
A sign of underwatering or very dry air. Keep the soil evenly moist and increase ambient humidity.
Faded or scorched foliage
Too much direct sun bleaches the pattern and burns leaves. Move to bright indirect light.
Spider mites and other pests
Dry conditions invite spider mites, plus mealybugs, aphids, and scale. Wipe leaves, raise humidity, and treat with insecticidal soap or neem.
Root rot
Caused by chronic overwatering, especially in winter. Let soil dry out more, improve drainage, and trim any mushy roots.
