To do this, you prune about mid August, this gives the subsequent growth enough time to sprout but not enough time to grow large before the end of the season. So basically, summer pruning will have a more dwarfing effect, this of course is the principal behind the summer pruning of fan trained and dwarf apple trees.
hope this helps, Lannerman.
