I am uploading a photo of the phlox from last August for you too see the difference. I dont understand how it could be sun damaged when it has been in this very spot for 3 years now.....and it only is in the sun until around 1PM.

I will watch to see if the new leaves change any or if anything else happens.

@Dustin, I will check the soil and see what I can come up with. I appreciate the help from all of you!!
