Hello all

Our plum tree has gone mad this year and has tons (almost literally) of
plumlets on it now. They're at an early stage - about the size of an
apricot stone (we are in Tynedale, Northumberland).

My friend looked at them and said "I've heard of June drop when a tree
gets like that".

What does that mean - anyone know? (my friend had heard the expression
but didn't know what it means) Does the tree divest itself of excess
fruit, or should one manually strip each bunch down to a more reasonable
number?

In any event I had better prop the branches tomorrow, or they'll be
breaking.

Cheers
John
