What Could Be Wrong With My Magnolia Tree?
The leaves on a well established magnolia tree in my yard is dropping leaves. They turn yellow with spots, like a fungus on a rose bush. I know nothing about caring for trees. Can anyone help me?

To tell the truth, it is likely the same disease that gets on your rosebushes, which is black spot. Trees are susceptible to it as well. Treat the tree with a fungicide and it will recover fine.
