I have 2 young Cherry Trees in my garden, all the new leaves on the growth from this year has now turned black and crispy. It is only effecting the leaves on the new stems and the growth located on existing stems seems to be un-effected for now.

The trees are a good distance away from each other.

The ground is usually very well drained but its very wet at the moment.

Black spots on the leaves of cherry trees are caused by fungal diseases. Cherry leaf spot is one fungal disease that attacks cherry trees, leaving black spore spots on the leaves and eventually killing the leaves. Another disease that attacks cherry trees is bacterial spot. The bacteria form brown spots on the underside of cherry leaves that eventually turn black.
Cherry tree leaves with black spots on them eventually turn yellow or brown and fall off the tree as they die. This weakens the tree further, as leaf loss limits the amount of photosynthesis the tree can perform. Fungi and bacteria also enter the tree itself and destroy it.
A picture may help also check if there is oozing from the bark it could also be canker

I may also be damage from the Cherry Blackfly as they target new shoots and the leaves curl up and turn black eventually
