How can I prevent thyis fast growth of so many new shoots, sometimes three from each cut?

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.
