    This depends on many factors. Your USDA zone will be important here. Some magnolias DO lose their leaves in cooler climates. Many do not, even in the coldest locations.

    Can you give me a little more information about your area, and the tree's environment? A photo will help greatly as well.

    These are fungal spots. This is common, and usually not a big threat to the tree. This will usually resolve itself over time. You can help it along some with some wettable sulfur. Just follow the instructions on the package.

    Can you include a photo? This could be a serious fungal infection. As a preventative measure, and a spot treatment you can use wettable sulfur in the soil around the tree. This can help kill off an infection, and will replace sulfur deficiencies in the soil.

    Here is an article on magnolia blooming problems. Get a soil test from Cal Extension Service. https://www.gardeningknowhow.com/ornamental/trees/magnolia/magnolia-blooming-problems.htm. It drought by itself caused the problem, I believe you would have seen leaf curl and leaf drop last summer during bud formation. If yours is simply not making buds in fall, nutrient deficiency may be to blame or you may be growing it outside the recommended zones 5-9. Look up your AHS Heat Zone. This magnolia is rated for 9-5 but the ag and AHS zones are different. http://www.plantmaps.com/interactive-california-heat-zones-map.php

    They will do just fine and slightly better if you growth them like you do rhododendron. They are very tolerant of most any soil type, but they do like to be in slightly acidic soils. So Yes, I would say that you are correct.

    Remove the damaged branches as soon as is safe to do so. A jagged cut is an invitation to disease and bugs. If the limb meets a branch(lateral) at a Y and the branch is at least 1/3 the diameter of the limb, you can trim back to the Y. If there is no such branch, take it back to the main trunk. Please read up on "branch collar". It is imperative that you make the cut properly or the wound may not heal. There are YouTube videos and google images of branch collar cuts.

    You should fertilize this at least once per year. This is likely the cause if it doesn't get fertilized regularly. I would also add dolomitic lime to keep the pH stable. This can help it along as well.
