Leaves wilting on trees

A number of trees, some of which that produce fruit (that aren't edible) have leaves that have been wilting since a heavy storm a few weeks ago.

From the pictures attached, can you give any advice. Should I remove the wilted leaves and leave the branches bare?

 

Isn't it winter there?

 

Yes, sorry I meant that they do produce fruit in Spring but will the wilted leaves affect the production?

 

Certainly looks like frost damage.

 

Thank you very much. Would you say the roots are damaged?

 

Very unlikely.
