I have apple , cherry, and plum trees. I have noticed the leaves have been eaten by something. Can anyone suggest how I stop this happening please.
Can you show us some photos of the damaged leaves please?
However, I would not be too concerned about leaf damage at this time of year ... the leaves have served their purpose and will soon be falling ... no harm to the tree.
