Brown Spots on Hydrangea Leaves
I have 8 hydrangeas in my garden, all on the same side of the house, facing east. About 3 of them didn't flower this year, and was worse, 5 of them have brown spots on their leaves. How can I remedy this? I live near the southern coast of Long Island, NY and I'm getting ready to cut all the plants for the winter.

It sounds like you may have a fungus. This is a common cause of spots on leaves. I would recommend treating the plants with a fungicide and destroying anything you prune from them so the fungus does not have anywhere to overwinter.
