Wilting rose bush. What to do?

I planted a rose (disneyland resort rose) in an appropriate container. She stared sprouting new growth but all of a sudden they're starting to wilt. I don't know what could be the problem as shes well watered and I used rose soil to plant her. Shes getting enough sunlight and the other two roses that are in containers next to her ( brandy and blue girl) are doing beautiful. I don't want to lose her because she is a show stopper. Any advice would be greatly appreciated!!!
