curling leaves on Fittonia
Quick answer
If your Fittonia has curling leaves, the most likely cause is: Physiological response to excessive transpiration. Leaves curl inward to conserve moisture when ambient humidity is <50% or when light intensity is too high for this understory species.
Start here:
- 1. Humidity Baseline: Maintain at least 60% RH. If leaves are curled but the soil is wet, the issue is definitely atmospheric; a humidifier is mandatory.
- 2. Light Gradient: Fittonias prefer medium indirect light. If leaves curl and look bleached, move them 2 feet further from the light source.

Water Temperature: Always use room-temperature water. Cold tap water can cause root shock and subsequent leaf curling.
- 4
Stop Excessive Misting: Over-misting can lead to mineral buildup on leaves, clogging stomata and causing distortion. Use a humidifier instead.
