Cold Damage on jade plant
What's Happening
Jade plants are native to South Africa and have evolved in frost-free subtropical climates. Their succulent tissues contain high water content that freezes and expands at temperatures below 40°F (4°C), rupturing cell walls. Cold damage typically appears within 24-48 hours of exposure and is irreversible.
How to Fix It
- 1
1. Move immediately: Relocate affected plant to warm area (65-75°F) with bright indirect light.

2. Assess damage: Soft, translucent leaves indicate severe freezing - remove these immediately. Firm leaves with dark spots may recover.

3. Withhold water: Do not water for 2 weeks post-cold exposure as damaged roots cannot process moisture and rot risk increases.

4. Prune cautiously: Remove only clearly mushy/damaged tissue. Wait 3-4 weeks to see if firm damaged leaves recover before removing.

5. Propagate if necessary: Take healthy stem cuttings above damage, allow to callus 5-7 days, then root in dry succulent mix.
How to Prevent It
Maintain minimum temperature of 50°F (10°C). Avoid placing near drafty windows in winter. Move plants away from air conditioning vents during summer.
