Can you tell me why my Port Wine Magnolias leaves are turning brown and falling off. I have sprayed once with a copper spray and Shield to no effect. I see no sign of borer and it is in a warm sheltered spot with good drainage.I have fertilized with Seasol. It has been in two years.
Regards Betty

Hi Betty. They could be suffering from drought. Check your watering over dry periods.
Happy gardening
