Calathea Loeseneri (Brazilian Star) problems — and how to fix them

Usually insufficient light or low humidity. Provide bright indirect light, keep humidity above 60%, and feed regularly in the growing season.

Hard or fluoridated water plus dry air. Switch to rainwater or distilled and raise humidity.

Overwatering or poor drainage stresses roots. Let the surface dry slightly and ensure the pot drains freely.

Underwatering or cold drafts. Keep soil consistently moist and temperatures warm and stable.
