I hope someone here can help me. I planted a lovely magnolia tree in my garden 6 weeks ago and I am sure it is dying. I don't know what to do. The flowers all withered and fell off and no leaves have appeared. I have only recently moved in to my new home and am trying to get the garden into shape, but I am fairly new to gardening. Please help. Thanks. I have planted several other trees and many plants and they are all thriving, so I'm unsure about what I've done wrong with the Magnolia tree.
