cold damage on Peace Lily
Quick answer
If your Peace Lily has cold damage, the most likely cause is: Peace lilies are tropical plants that suffer severe damage when exposed to temperatures below 50°F (10°C). Cold damage occurs from: leaving plants in cars during winter transport, drafty windows, or homes that drop below 55°F. Ice crystals form in cells causing tissue death. Key risk: if the basal growth point (crown) freezes, the plant cannot recover. Leaves turn black, wilt, and become mushy.
Start here:
- 1. Inspect the crown/base of plant: if firm and green, plant is salvageable; if mushy/black, growth point is damaged and plant likely cannot recover
- 2. Trim all blackened, mushy leaves and stems at the base with clean shears - damaged tissue won't recover and wastes energy

How to reverse cold damage on Peace Lily
- 1
Inspect the crown/base of plant: if firm and green, plant is salvageable; if mushy/black, growth point is damaged and plant likely cannot recover
- 2
Trim all blackened, mushy leaves and stems at the base with clean shears - damaged tissue won't recover and wastes energy
- 3
Place entire plant in a clear plastic bag for 2-3 days to create humidity dome - helps rehydrate leaves and soil
- 4
Move to warm location (65-80°F) with bright indirect light - avoid direct sun on weakened tissue
- 5
Water sparingly with room-temperature water only when top inch is dry - cold-damaged roots are prone to rot
- 6
Wait 2-4 weeks for new growth from crown - peace lilies are resilient and often bounce back even from severe damage
Keep cold damage off this Peace Lily
Never expose peace lilies to temperatures below 50°F. When transporting in winter, wrap pot in insulation, preheat car, and minimize exposure time. Keep away from drafty windows and doors. Use smart thermostats to maintain minimum 60°F during absences.
