Is there a way to prune a star magnolia that will keep it small and shaped nicely? Every year I end up pruning it twice which is not the best for blooms. I cut it back in the spring after it blooms to about 5 feet, and by fall it is 10-12 feet. It is in front of the house between the walkway and house, so I don't want it to get so big. It is quite healthy and does bloom well.
