Can potted lime exposed to freezing temps be saved?

Question

I want to save a frozen potted lime tree. I have a potted dwarf lime tree that was exposed to unexpected frigid temperatures for a couple of days. It was covered, but still it was very cold and somewhat exposed. It has lost the majority of its leaves. I do not know what to do to save it. Should I cut it down low and start over? It produced over 28 limes this past summer and fall. I am clueless about what to do with it to save it. Please help.

The best option is to wait until spring (while protecting the plant from any further winter damage) and see if the tree starts growing again. Even if it loses all its leaves, the trunk may still be alive and able to put out leaves again in the spring. You'll then be able to see which parts of the tree are dead, and prune accordingly.

Here's how to check whether a tree is completely dead:
