Magnolia grandiflora 'Exmouth' Magnolia

Posted: 02 December 2011
Overall: Can someone help? I have an established mge planted 7 years ago,approx. 3m.tall. It has been healthy and flowered over the years. However toward end of last year, some leaves turned brown and dropped off.Survived the frosts.Whilst new growth has appeared, leaves are still dropping in abundance. The flowers are opening then turning brown and dropping within a day. I have had a garden makeover this year and I know that a layer of topsoil has been dropped around the plant. What am I doing wrong?
