Hydrangea Care Concern
I have several hydrangea plants. Two are the same and are in pots outdoors. The one is doing fine. The other one's leaves were all curled and wet-like (gooey). Then I have three that are planted in the ground. Those too have the curled leaves and I don't think they look normal. Is there a bug that is eating at it (can't see anything) or some other disease?

It sounds like aphids or spider mites, both of which are quite small so you may need to look very closely to spot them. It could also be due to a fungus. I would recommend treating the plants with neem oil. This will treat both the pest issue as well as any fungal probelms. These articles will help:
