QuestionsHow to growTrees and ShrubsPlantingMagnolia ‘Susan’ 0 Vote Up Vote Down ionela Papai asked 14 years ago I planted a magnolia Susan this spring in the garden and it was full of flowers in May but after they were gone no leaves appeared. What do you think happened? 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 7 years ago It is possible that the tree had a root rot and died just after flowering. Or if leaves appeared briefly or the buds began to break, that snails ate the leaves before they expanded.
