cold damage on Aloe Vera
Quick answer
If your Aloe Vera has cold damage, the most likely cause is: Aloe Vera cold damage occurs when temperatures drop below 50°F (10°C), causing cellular ice crystal formation that ruptures leaf tissue. Frost damage manifests as mushy, darkened patches that progress to blackened, necrotic tissue. Aloe is not frost-tolerant and should be protected from cold drafts, unheated rooms, and outdoor temperatures below 55°F. The succulent's high water content makes it particularly vulnerable to freezing.
Start here:
- 1. Move plant to warmer location immediately (65-85°F range)
- 2. Remove damaged leaves at the base with sterilized scissors if tissue is completely dead
