I know that Pieris are prone to root rot- is there a possibility of knowing if this is what happened to my plant?
This Pieris japonica 'Shojo" was installed last fall and has done very well until about one month ago. We had a very dry spell and I was watering twice a week, deeply. There are three others right next to it that are doing fine.
My soil is very slightly acid in the 6.8 range, and the site gets morning sun until about 10 am, bright indirect thereafter.

I am replacing this one- once. If it happens again I will relocate the remining three and call it a bust.
There are no insects apparent, although I did have lacebugs nearby. I caught them early and dealt with them.
