I have a magnolia susan which never seems to flower well, flowering is sparse at best, as per the photo where you can see just a few flowers at the very top of the plant.
Its in clay soil and gets sun most of the day. I have a magnolia tree nearby which flowers wonderfully every year. The magnolia susan is about 6ft tall. I haven't ever pruned it and I'm wondering if I should?
