Water I think Patricia
when you moved your hydrangea did you tease the roots out? You said it was pot bound.
I think you will find your hydrangea roots have not grown much in the soil and therefore been unable to take up enough water.
hydrangeas need water and quite a bit of it
I would be inclined to lift your plant and loosen the roots. Then put plenty of manure or compost mixed in with the soil. Water well. Mulch thickly. Bet your plamt grows better next year....if you water it occasionally
