The Q&A Archives: I have a dwarf Magnolia tree

Question: I have a dwarf Magnolia tree and it is blooming this year and now there is black spots on the leafs and the blooms are dying before they open up. What can I do to save my tree?Thanks, Judy
I've had the tree for one year and this is the first time that it has bloomed.

Answer: I can't be sure without seeing the plant, but what you describe sounds like bacterial blight (which is common in magnolias and other ornamental shrubs). If so, you may be able to control it with a fall spray of copper. Before treating your tree, though, why not take a sample of the affected leaves and flowers to your local Cooperative Extension office or Master Gardener clinic for positive identification of the problem? Helpful folks there will be able to offer some control measures. Best wishes with your magnolia!
