I live in Southern New England and have a peach tree growing in the ground in my yard. I have had it for about two years. The weather this summer has been fairly warm, averaging mid to upper 80s.
I am seeing purple streaks / blotches in some of my cherry leaves along with holes that appear to be insect damage. Damaged leaves fall out easily. The discoloration is not uniform but appears most often in the center of each leaf. The majority of the plant other than some of its leaves look very healthy. See picture below. This is the same plant I talked about in my other question here.
What is causing the damage to the leaves of my peach tree?
