Aloe Vera Cold Damage — Signs and Recovery
Aloe Vera (Aloe vera)
Symptoms
- translucent or water-soaked patches on leaves
- patches appearing after cold exposure
- mushy sections that were firm before
- brown patches that appeared suddenly
Causes
Freeze or near-freeze temperatures
Aloe vera is damaged by temperatures below 28–32°F, and stressed significantly by temperatures below 45–50°F over extended periods. When the cells freeze, the ice crystals rupture cell membranes. The result is the characteristic water-soaked, translucent patches that later turn tan or brown. Unlike overwatering, freeze damage has a clear triggering event (cold night, outdoor frost, cold window contact) and doesn't spread after the cold exposure ends.
How to Fix It
- 1
Move the plant to a warm location immediately after cold exposure.
- 2
Do NOT cut the damaged areas immediately. Allow 1–2 weeks for the extent of the damage to become clear — some areas that appear damaged initially may recover.
- 3
After 2 weeks, remove the sections that have dried to brown and crispy. Cut to healthy green tissue with sterile scissors.
- 4
If the damage is extensive (more than half the plant), save any undamaged or minimally-damaged leaves for propagation — each large, healthy leaf base can potentially root and grow a new plant.
- 5
Resume normal care. If the root system and core of the plant are undamaged, new growth will emerge from the center.
Prevention
- Keep above 55°F year-round
- Move outdoor plants inside well before the first frost
- Keep away from winter-cold windows that may drop below 50°F on cold nights
- Never leave in an unheated greenhouse or car overnight in cold weather
