What's wrong with my hydrangeas?

[hamster]

I have some 4 year old hydrangeas that are suddenly not looking so hot.

One only has leaves on the top 1/3 of the plant for the most part. Now suddenly the other one has a bunch of brown, wilted leaves like they are dying. The already questionable one has some, but not as many.

What gives? I've only ever pruned old, dead wood. I'll try to add pics but I usually struggle.

Did you get some frost?

We've had a little bit the last day or two, but nothing that I would expect to harm a hydrangea. The others in the yard are fine.

It looks like it's still leafing out. When it's done, then prune off any dead tips.
Your hydrangea looks better than mine.
