Troubleshooting
Calathea Undulata problems — and how to fix them
Calathea Undulata (Goeppertia undulata) 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 leaf edges and tips
Low humidity or hard/fluoridated tap water; raise humidity well and use filtered, distilled or rainwater.
Curling leaves
Underwatering or dry air; this thirsty species needs consistently moist soil and high humidity.
Yellowing leaves
Overwatering or soggy soil; ensure drainage and let only the surface dry between waterings.
Faded feather pattern
Too much direct sun bleaches the markings; move to bright indirect light.
