Plum tree blight
We have an old plum trees that we inherited on the property we bought two years ago. Last year the leaves and fruit were quite diseased, this year all the leaves are diseased (full of holes and no fruit) and two newly planted apple trees nearby caught the blight too. I did not find the problem or how to treat it online, is it possible for you to figure out what the issue is and how to take care of it, other than cutting the tree down? Thanks much. Arlette

It looks like bacterial leaf spot. There are treatments and if you like the tree it is probably worth doing if the tree is reasonably healthy. Fruit trees often alternate years of fruit production and no production.
