crispy fronds on Nephrolepis Exaltata
Quick answer
If your Nephrolepis Exaltata has crispy fronds, the most likely cause is: Crispy brown fronds result from three mechanisms: 1) Low humidity (<50% RH) causes marginal frond necrosis as thin cuticles cannot retain moisture; 2) Terra cotta/porous pots accelerate soil drying, causing desiccation despite regular watering; 3) Misting creates prolonged leaf wetness that promotes fungal infections causing brown spots.
Start here:
- 1. For humidity stress: relocate to bathroom with shower steam, install humidifier (60-80% RH target), or use pebble tray
- 2. For porous pots: repot into non-porous plastic or glazed ceramic pot
