Hi! Two things:

The edges of my peony leaves on one plant are tight, as if there was a rubber band running along the edge and forcing the leaves to pucker. It is showing up on more leaves as the season continues. Does that demonstrate a deficiency of some kind? The plant is flowering as expected. (pic 1)

(pic 2) I have a hydrangea that was eaten multiple times by deer last year. I put it in a pot on my deck and it finished the year ugly and covered in brown spots (looking sick). It has regrown lush and green this spring, but the flower heads are turning brown and drying up before developing. Does anyone know what is happening?

I will appreciate any advice/help anyone can give me.
