Cold Temperature Stress on parlor palm

parlor palm with cold temperature stress

What's Happening

Parlor Palms are tropical plants adapted to consistent 65-80°F temperatures. Exposure to cold drafts from windows, air conditioning vents, or entryways causes chilling injury, manifesting as dark brown or black spots on fronds. Temperatures below 55°F stress the plant and slow growth; below 45°F causes permanent tissue damage.

How to Fix It

  1. 1

    Move plant away from cold drafts, AC vents, or poorly insulated windows immediately

  2. 2

    Maintain stable temperature: Ideal range 65-80°F, minimum 60°F

  3. 3

    Increase humidity to 50-60% to help plant recover from temperature stress

  4. 4

    Trim severely damaged fronds at base once they turn completely brown

  5. 5

    Monitor for secondary issues: Cold-stressed palms are more susceptible to root rot and pests

  6. 6

    Resume normal care once temperature stabilizes—recovery takes 2-4 weeks

How to Prevent It

Maintain consistent temperatures between 65-80°F year-round. Position away from cold windows in winter, air conditioning vents, and drafty doors. Avoid placing near heating vents that create hot, dry air.
