Troubleshooting
Rose-painted Calathea (Dottie) problems — and how to fix them
Rose-painted Calathea (Dottie) (Goeppertia roseopicta) 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, crispy leaf edges
Usually caused by tap-water fluoride/chlorine/salts, low humidity, or overfeeding. Switch to distilled or rainwater, raise humidity above 50%, and dilute fertiliser.
Curling or limp leaves
A sign of underwatering or air that is too dry. Check that the top inch of soil hasn't fully dried out and boost humidity; leaves should recover after a thorough watering.
Yellowing leaves
Most often overwatering or soggy, poorly draining soil leading to root rot. Let the top layer dry between waterings and ensure the pot drains freely.
Faded pink markings / reversion to green
Too little light dulls the variegation. Move to brighter indirect light, but avoid direct sun, which scorches and bleaches the foliage.
Spider mites and mealybugs
Common when air is dry and soil too dry. Inspect leaf undersides; wipe with a mild dish-soap solution or treat with insecticidal soap, and raise humidity as a deterrent.
Leaves not moving at night
The prayer-like nyctinasty can stall under stress from inconsistent watering or temperature swings. Keep moisture even and temperatures stable at 18-24C, away from draughts.
