I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
The brown shrub is in big trouble. I would just watch and wait while keeping the soil moist but not too soggy wet. If new growth appears then prune out any dead branches past that point. In a month or so you should see something if it is going to survive.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
