We recently bought a Little Lamb Hydrangea from a local nursery. It has been in the ground for nearly two weeks and is looking very unhealthy. Last weekend, the leaves began to shrivel and had some holes on them. Now all the leaves are close to falling off and the flowers are beginning to shrivel. I took a sample of the leaves to the nursery and they thought I was probably watering too much. They also thought it could be from overhead watering. I have backed off on watering, but it just continues to get worse. Any thoughts??
