What is the white stuff on my hydrangea?
Question:I have two hydrangea bushes with white, almost looks like bird poop, on the underside of the leaves and some on the stems.
I wasn't sure if it was a fungus and what to do about it.
I don't want my bushes to be damaged.
Answers:
Could be spittlebugs - they leave a white foamy stuff, but don't do harm. Or butterfly/moth larvae. Keep an eye on it and if it doesn't seem to be hurting the plant (lots of leaves curling up, stems dying) I'd leave it alone.

You must have very perverse neighbours then.
Here is a list of Hydrangea diseases

If you dont see it on this list your probably safe.
It sounds like powdery mildew. Only water in the morning so the leaves have time to dry out before dark - when mildew can form.
There is a certain butterfly that has larva shaped like and looking like bird poop--so the birds won't eat them. Maybe that's it. Check and see if it's actually a living creature. What tipped me off is that it is on the stems as well as the leaves.
