Hi royroy, Pruning any plant when its dormant generally encourages
growth, as the subsequent growth has all season to grow, thus becoming
large. Having pruned these new growths again now, all that will happen
will be a repeat performance of last year, so you need to break this
cycle ! 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.
