Troubleshooting
Rattlesnake Plant problems — and how to fix them
Rattlesnake Plant (Calathea lancifolia) 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 leaf tips and edges
Most commonly caused by low humidity, fluoride or chlorine in tap water, or inconsistent watering. Switch to filtered or rainwater and increase ambient humidity above 50%.
Leaves curling inward
A sign of under-watering or very low humidity. Check soil moisture and move the plant away from heating vents or air conditioning. Leaves should uncurl within hours of watering if dryness was the cause.
Yellow leaves and mushy stems
Indicates overwatering and potential root rot. Allow the top inch of soil to dry before watering, ensure the pot has drainage holes, and repot into fresh mix if roots are brown and soft.
