Hi Melissa, for some sensitive plants of mine I wrap them with burlap. if freeze warnings is in forecast. Make sure it is kept dry and move plant container closer to your house. I have my jade outdoors and it has endured occasional 20-21 F during winter. It will get really chilled colors, reddish hues.
So far with mine, I have not wrapped it all these years during winter, but it is always in that spot right beside our house.You are in higher elevation, in case you also get snow fall forecast, then definitely move it indoors.
This was my jade taken Feb 2012
