First, this is a young tree. It takes approximately two years for a woody ornamental or tree to even accept a site, meaning they are susceptible to transplant shock as well as other issues during that two years. Plants may struggle and show signs of stress for several years if the environment is extreme during that time. We had a wet spring 2019, then in July 2019, immediately endured 90+ degree temperatures along with drought. 2020 has been wet as well with one of the wettest summers on record.    

Next, this is a man-made plant with the grafted weeping branches grafted onto upright stock. A grafted plant can have issues at the graft sight. In the center photo there are cracks between branches in the graft zone. That is not uncommon. Cracking can be caused by wounds or sunscald. Most cracks do heal within the plant. If sapping occurs then there may be a problem with gummosis.

Cherries, peaches and other stone fruit are related (even the ornamental ones) so they can share some of the same conditions, problems and diseases. Disease usually sets in at bloom time. The following spray schedule applies to all stone fruit trees. The disease and insect control spray schedule publication, ID 21, has information on sprayers, how the chemicals work and likely pests and diseases to watch out for:

It is too late to spray for any disease as fungicides are protectants not curative. They are applied early and should be applied according to label instructions following a schedule, like the one on peaches/cherries in the above linked publication.  

We have another publication- Growing Peaches in Kentucky, that might be helpful as cherries and peaches share many problems: http://www2.ca.uky.edu/agcomm/pubs/ho/ho57/ho57.pdf

Holes in leaves at this time of year are usually caused by caterpillar or beetles. they are already gone by the time we see the damage and the plant is going to be discarding them soon for winter.

Please let me know if I can help you further!
