Magnolia tree dropping leaves
We have a 15-foot-tall magnolia on the parkway in front of our house. For the past few months, it's been dropping an unusual numbers of leaves.
The leaf-drop has progressed from the lower branches and from the trunk, with leaves turning a spotted yellow before falling. The lower branches are looking pretty dead and bare now. It's been a very rainy summer, but we have fairly sandy and well-draining soil.
Anyone out there have an idea what might be the matter? All theories much appreciated!
