Cherry tree+ lose of fruit and sparse leaves
I have an establishes Sweet Cherry tree, this year it bloomed O.K and I saw the fruit coming on. Then overnight it had all gone, so now the tree has no fruit and only sparse leaves, which are clustered on the ends of the branches.
I grow organically, I mulch in the spring and use rain water. My soil is free draing , there's no sign of disease, any advice will be welcome.
