What's wrong with this tree?
Hi there, I'm not sure what type of tree this is. It had lovely white flowers in the spring, and seemed okay for much of the summer, but it is now not doing well. Most if not all of the leaves are filled with holes, and are falling/have fallen off of the tree already. It also has some webs in the upper branches. Can you tell what is wrong with it? Please let me know if you need any other photos. Thank you.
The tree looks like a type of cherry, possibly Yoshino.
The holes in the leaves look like cherry shot hole, a fungal disease. This can be common when we have wet spring weather and may continue to infect leaves throughout the growing season if rainy weather persists. You will also see some defoliation. In most cases trees recover from these diseases and no treatment is necessary. Remove and dispose of fallen leaves in the fall to reduce overwintering pathogens.
