Q.Oleander Shrubs
I plantedĀ four pink oleander shrubs early last spring. They were beautiful and were really growing until we had the extreme winter in north Texas. Now they have lost all of their leaves and look dead. What should I do? Is there a possibility that they will come back? I have never had this type of plant before and do not know if I should cut them down to the ground or what?

If the stems are still alive, they will regrow their leaves. I would give them a month, and if you do not see growth by then, they are most likely dead. These articles will help you as well:
