cold damage on Kalanchoe
Quick answer
If your Kalanchoe has cold damage, the most likely cause is: Kalanchoe tomentosa (Panda Plant) originates from Madagascar's warm climate and has low cold tolerance. Exposure to temperatures below freezing causes ice crystal formation inside leaf cells, leading to irreversible cell membrane damage. Even brief frost exposure can kill the plant.
Start here:
- 1. 1. Bring plant indoors to a warm location when frost is forecast
- 2. 2. Place near a south-facing window with maximum sunlight exposure

How to reverse cold damage on Kalanchoe
- 1
1. Bring plant indoors to a warm location when frost is forecast

2. Place near a south-facing window with maximum sunlight exposure
- 3
3. Reduce watering frequency in winter — the plant's growth slows significantly
