Expert Response
Hello,
Your Dogwood appears to have spot anthracnose that causes distortion of the leaves, bracts and fruit. Read more here: https://plantpathology.ca.uky.edu/files/ppfs-or-w-06.pdf
And here: https://plants.ces.ncsu.edu/plants/cornus-kousa/
Spot anthracnose is not considered detrimental to the tree and the best way to control it is to carry out the cultural practices recommended in the articles.
To obtain a definitive diagnosis and management recommendations send a photo/sample to MSU Extension’s Plant and Pest Diagnostic Lab.
A certified arborist can assess your tree. To find an arborist in your area, go to www.treesaregood.org the website of the International Society of Arboriculture.
