cherry Tree and grapefruit bush

[olly]

Unless your cherry is a Morello variety, which is self fertile, you will need a male and female tree of the same species to cross- pollinate, to get fruit.
As for the grapefruit, it could be many things, if you've had fruit off it in previous years, did you get any blossom?
If so, did you water well when the fruit set, as it's been a very dry Winter, and the fruits will drop if not given sufficient water?
Was it exposed to the high winds we've had this year?
So many things can have gone wrong, that it's a hard question to answer.
