This morning, I discovered that the subfreezing temperatures damaged my mini jade plant that I keep on the deck outside.
After reading about what to do with plants damaged by subfreezing temperatures, I bought it inside where it will stay to revive. I placed it where it will get lots of light. Since it wasn't totally damaged, it should recover. Once we get back into the warmer months, it will go back out (if it has healed).
According to SF Gate:
Tropical and subtropical plants such as jade plant (Crassula argentea) don't possess the tolerance to survive extreme temperature drops, and suffer severe injury and even death if exposed to a hard frost. Jade plant grows in U.S. Department of Agriculture plant hardiness zones 10 through 11, where it requires daytime temperatures between 65 and 75 degrees Fahrenheit, and nighttime temperatures between 50 and 55 degrees. The survivability of a jade plant left outside during an unexpected frost largely depends on the duration of exposure to freezing temperatures. Exercise patience and care when helping a frost-injured jade plant.
If desired, you can leave the damaged jade plant parts untouched, allowing them to fall off naturally after the plant heals. This is actually the preferred method of frost damage care for outdoor plants because the damaged plant material provides protection to the rest of the plant.
