Help! What's wrong with my Hydrangea?
I have a beautiful old hydrangea, it was here when we moved in 8 years ago and was well established then. Its in a protected spot and has always bloomed beautifully. This year I noticed there was less foliage than usual and there are lots of smallish flower heads instead of the usual large fluffy ones. Now all the flowers are turning brown, but not really dry, they look dirty. I found a couple of leaves that have brown spots that could be anthracnose, but I think I would have expected more leaf damage. Here's a link to some pics. Please let me know if you have any ideas.
