Hello experts, I am desperately looking for information on what's wrong with my 8 ft tall Magnolia Grandiflora which I planted 2 months ago. It was putting out a lot of flowers and looked happy in the middle of the garden in the lawn. About a week ago it started to look ill. Please see photos. Is it a fungi infection? Should I remove grass surrounding it? What can I do? Thank you so much for your help.
