When do you prune? I've got an olive in a pot that is about 2 or 3 years
old, it gets as far as tiny little fruit every year, but doesn't go any
further. It's getting a bit one-sided and thought I ought to prune it back,
but haven't got to finding out how and when to do it yet.

Advice from someone who's managed to not kill one always appreciated. ;-)
