Answer: It isn't unusual for newly transplanted shrubs to go through an adjustment period; wilting and looking pathetic is just part of the game. The should rebound in a few weeks, once the roots become established. Hydrangeas prefer to grow in morning sun and afternoon shade. If they are sitting in afternoon sun they will look terribly droopy, but will recover overnight. The best thing you can do for your hydrangeas is to water them deeply once each week. They should recover from the transplant in a week or two.
Best wishes with your new plants!
