This lovely magnolia was beautifully shaped and seven-feet high, but our wet Vancouver Island spring following a cold snap or two in winter and last year's heat dome killed several large, structural branches. I removed the dieback and was left with basically a few long lower branches. It looked pathetic, but then got a heavy flush of new leaves, all growing from new vertical stems. Now a lot of the leaves seem to have a fungus of some kind (which has showed up in previous years). My question is: do I attempt to prune the magnolia or just leave it alone for a year? Will some of those verticals branch out or just behave like suckers? Regarding the fungal infection on the leaves: do I remove each leaf and discard it? I guess the larger question is, do these magnolias generally do well in our climate, or should I cut it down and replace it with something else. It is planted on a slight slope and receives afternoon sun.
