Why Are The Leaves Dropping On My Stella Cherry Tree,

Question

My container grown “Stella” cherry tree (3rd season) had beautiful flowers in the spring and went on to produce a good crop of fruit.This has been harvested but the leaves are now dropping quite rapidly. Only 1 or 2 are yellow the rest look quite normal, I can’t see any sign of aphids, mildew or the like so I don’t know whether to spray and if so, what with? Sorry don’t know how to send photo?

Answer 1

I suggest checking the undersides of the leaves that are dropping. Sometimes they are diseased but don't turn yellow before they drop. Here's some info:
