David,I've found most magnolias take very well to pruning! I regularly cut back mine, as they would certainly overtake my smallish garden (smallish meaning large for the city, postage stamp for the rest of you). The only one I have allowed full romp is 'Elizabeth', as she is relatively small, at 10m and a bit on the columnar side. Otherwise, I find between 3-4m a good height for most.Or did I misunderstand thyn comment?
