Wondering if someone can help. We planted about 15 beautiful Magnolia trees approx 3 years ago. All are growing beautifully except for 1 which appears to be dying. It was fine up until 3-4 months ago when the leaves started browning. I tried giving it extra water but didnt seem to help. Can anyone help? Is it dead? Can it be saved? It seems to be sprouting towards the bottom as pictured which makes me think its still alive. Appreciate the help!
