I planted 3 rose bushes 3 days ago and they look like they are dying. They're wilting terribly.?

Someone please advise what to do. Is bone meal and Vitamin B good for the roots like I was told. They get 3 hours of sun a day. They were fine in the pots and the next day after planting they were drooping very badly. I am sad and beside myself with worry. Don't have a green thumb.
