Hydrangea

Why are the leaves on my hydrangeas turning black? I recently transplanted a few potted hydrangea plants. They were the type you buy in a smaller pot as a gift. Some are in sunnier parts than others. I see new growth, but the color change in the leaves is really strange.

It could be either black spot or sooty mold. Both are treatable and in most cases, not fatal to the plants. These articles will help:
