Ornamental cherry with shot hole leaf
Ornamental cherry trees can have a disease called 'shothole' but the damage you have there looks like insect feeding, so we'd suspect caterpillars or beetles. The most likely to skeletonize like that are beetles, likely Japanese beetles.
How does the rest of the tree look? What percentage of the leaves would you say look like this?
If the tree is large like you say and otherwise healthy, it shouldn't be a problem, especially this late in the growing season.
Top of the tree is very thin not many leaves from spring left and bottom branches are still fairly green and full with what seems to be normal dead mixed in. I couldn’t see any other signs of pests. Are there other signs I should look for to confirm beatles? And would pesticides next spring help the health of the tree?
How did the tree look overall in the spring? Was it thin then?
How old is the tree? Did it bloom well? What color? Are there dead limbs that never leafed out? Any additional info would be helpful.
If you can, we'd like to see some digital photos of the tree. Up to three at a time can be attached at a time, directly to this reply by using the Choose File tabs below.
An overall shot of the tree, some leafy limb photo and a picture that includes the area where the trunk goes into the ground would be most helpful.
It’s a large cherry at least thirty years old, the spring growth was full and with many white blooms. The tree had not been trimmed or thinned in years and once the blooms started to drop this began. There are several dead branches that have no leaves growth but they seem to have been dead for a few seasons. Some of the limbs have started to die tip back but this seems to be more recent
Cherry trees are not long-lived trees. Their lifespan in our area is about 25-30 years. So at this point, you should have an arborist look at the tree for an evaluation. At a minimum, the arborist should prune out the dead branches. If we should have a prolonged dry period the tree should be watered.
