Greengage Tree And Plumb

[getonwithit]

I planted a greengage tree last year which seamed to take to the position very well it has 4 branches about 4 ft long in April all the leaves fell off other than a foot at the end of each branch 4 fruits grew and in the last 2 weeks two of them fell off , I picked one of the remaining greengage yesterday which was ripe and delicious , I was hoping for more than two fruit ?
I also planted a Victoria plumb at the same time , half of the tree got leaf curl which I have treated it has a lot of fruit which seams very small and some of the plumbs are very shrivelled ?
Advice would be greatly appreciated thanks

Lead poisoning?

Its possible that the distorted curled leaves are a disease carried by aphids.
what I've found affective, as a none chemical option is blasting the leaves (particularly the under sides) with a strong blast of water from a garden hose.
