Dying Southern Magnolia ( Magnolia Grandiflora) Tree
I have a 15-20 year old Magnolia tree, about 30 feet tall, and that has been extremely healthy until this year. Attached are several pictures. I believe it is a Southern Magnolia ( Magnolia Grandiflora) and is in full sun. There are no competing plants near it and nothing has been disturbed in its root system. Thank you for any advice you may have, as I really don't want to lose this tree. There is also another identical tree in another part of our yard that is doing very well...

Detective work is needed to find out what has happened. Share photos of the root area and the trunk. Describe irrigation during these recent drought years. Are there lesions or evidence of damage on the bark anywhere?
