Similarly, how do you treat damaged tree bark? The warm sun heats one side of the tree, making the bark tissue less cold hardy and resulting in inactive cells.

These cells can freeze and die at night as temperatures drop, leading to discolored. As the tree grows wider and the bark splits a bit it will find a weak spot (for a number of reasons) and just peel off naturally (it will be more noticeable with younger trees).
