curling leaves on Chinese Evergreen
Quick answer
If your Chinese Evergreen has curling leaves, the most likely cause is: Curling in Aglaonema typically presents in three forms: 1) Downward curling due to humidity stress (<40% RH) as the plant attempts to reduce transpiration; 2) Inward/Protective curling from photoinhibition when light intensity exceeds 1000 lux; 3) Juvenile Vernation where new leaves emerge as tight, wonky spears that take 2-6 weeks to naturally unfurl. Consistent downward curling while soil is moist can also signal root dysfunction (rot) preventing hydraulic turgor.
Start here:
- 1. Humidity Check: If leaves curl downward and edges feel dry, increase ambient humidity to 50-60% using a pebble tray or humidifier.
- 2. Light Audit: If curling affects newest/top leaves, move the plant 3-5 feet away from the light source or use a sheer curtain.

How to reverse curling leaves on Chinese Evergreen
- 1
Humidity Check: If leaves curl downward and edges feel dry, increase ambient humidity to 50-60% using a pebble tray or humidifier.

Light Audit: If curling affects newest/top leaves, move the plant 3-5 feet away from the light source or use a sheer curtain.

Patience: If the curled leaf is at the center/top of a stem, it is a new growth spear; do not force it open, as this can cause abortion or permanent scarring.

Root Inspection: If curling persists despite high humidity and correct light, unpot to check for mushy roots.
Keep curling leaves off this Chinese Evergreen
Maintain stable temperatures (65-75�F) and 50%+ humidity; provide bright indirect light (200-400 foot-candles); avoid placing in direct paths of AC/heating drafts; use a moisture meter to ensure top 2 inches dry before watering.
