Hello,

It sounds like your tart cherry tree may be experiencing symptoms that could be associated with a disease. Common cherry tree diseases in Michigan include cherry leaf spot, powdery mildew, and Phytophthora root, crown, and collar rot. More information at this link:

The symptoms you described, such as shriveled and browned blossoms and abnormal leafing, could be caused by cherry leaf spots, which are known to cause defoliation and impact the tree’s ability to build up proper reserves for overwintering. This disease is particularly important to manage, as trees that defoliate prematurely cannot build up proper reserves for overwintering and are more likely to die due to extremely cold temperatures.

For immediate action, you might start by removing any fallen leaves or debris around the tree to prevent the spreading of potential diseases. Also, ensure that the tree is not over-watered or under-watered, as proper watering can sometimes alleviate stress on the tree and improve its overall health.
