crispy leaves on Fittonia
Quick answer
If your Fittonia has crispy leaves, the most likely cause is: Desiccation of leaf margins due to low ambient humidity (<50% RH) or direct sunlight scorch. Fittonias have high transpiration rates and thin cuticles, making them vulnerable to dry air.
Start here:
- 1. Humidifier: Move the plant near a humidifier targeting 60-70% RH. Pebble trays are often insufficient for Fittonias.
- 2. Terrarium Mode: Place the plant in a glass terrarium or under a large jar to maintain high localized humidity (80%+). This is the best long-term solution for Nerve Plants.

Water Quality: Use distilled or rainwater if your tap water is hard; mineral salts can accumulate at leaf edges and cause burn.

Sun Protection: Move away from direct sun. Bright indirect light (e.g., North window) is ideal.
Keep crispy leaves off this Fittonia
Monitor RH with a hygrometer; never let it dip below 50%. Group with other thirsty tropicals. Avoid misting in rooms with poor airflow as it can lead to fungal spots.
