Answer: I don't think there's much to worry about - you planted it with care, from what I can tell. Most newly transplanted shrubs and trees go through a period of adjustment we refer to as transplant shock. It simply means that until the roots become re-established in their new home, your tree rose is likely to look pathetic. All you need to do to ensure success is to water it deeply once a week. When the roots are firmly established, which may take 2-3 weeks, it should perk up and begin to produce new growth. When you see new growth you can prune away any dead stems or branches and pull off any dead leaves. I'm sure your rose will recover and you'll be able to enjoy the flowers later this summer.
Best wishes with your garden!
