    Most likely fungal leaf spots which don't require any intervention. Just pick up the fallen leaves and discard them in the trash so as not to spread the fungus.

    YOu don't say how old the tree is or how you went about transplanting it, so it's hard to say. The deed is done, though, so now about all you can do is keep it well watered, but make sure it drains well, no standing water, and keep your fingers crossed.

    Here are a couple of articles about moving trees and pruning magnolias.

    A few things appear to be causing the issue. First, it is important to measure and follow instructions on feed packaging to avoid over, or underfeeding. Because this is an acid mix, overfeeding will lead to a severely low pH. this can cause nutrient lock out, or many symptoms of what you are seeing here.

    Another thing that can cause these symptoms is overwatering. This is the most common issue. They do not tolerate being wet constantly without a period to dry out thoroughly down to about 3 or 4 inches.

    It sounds like fungal issues at work. Powdery mildew is the white floury stuff and it is caused by too much shade. The spots are from a different fungal infection. Clean up any leaf debris in the fall so as not to spread the fungal spores to next year. Botrytis blight, another fungal infection. could also be present. Read the information below to determine if that is what is causing the bud drop.

    It appears to be fungal/bacterial, but this is not Verticillium.

    It sounds like the tree was planted a little too late in the year. It is best to plant these in early Spring, since they are quite cold tolerant, but won't take well to the soil in the heat. Pair this with lots of water in attempt to compensate for hot weather and you have the perfect recipe for infection.

    It sounds like you are already treating the best that you can for the upper portions of the tree. Cooler weather will take care of the rest. You can help it out by removing any heavily infected growth or anything that is completely dead, but don't butcher it up too badly at this point.

    I would also suggest WETTABLE SULFUR and DOLOMITIC LIME together in the soil. Do this once per year around the tree where its roots extend to. This will help keep infections at bay, and treat existing ones.

    Yes, they are just barely hardy in your area, as you are at the edge of their survival zone. With some protection from summer heat, you should see normal growth.

    I t could be so many different things. Water shortage. Toxin in soil. Planting techniques.
    Fungus. Inadequate root protection during transit.
    How was it transported?
