MAGNOLIA DISEASE PROBLEMS
Magnolia may be subject to leaf spots caused by the
bacterium Pseudomonas syringae or a large number of fungi.
Leaf spots rarely require chemical controls. Rake up and
dispose of infected leaves.
Canker diseases will kill branches. Cankers on branches
can be pruned out. Keep trees healthy with regular
fertilization and by watering in dry weather.
Verticillium wilt may cause death of a few branches or may
kill the tree. Prune out dead branches and fertilize with
high nitrogen fertilizer.
