None of my magnolias have flowered, ever. They get fertiliser. They are not overly wet or overly dry.
There are several things for you to look into. Make sure that your magnolia is a variety that is hardy in your area. Make sure that it has enough sun. Make sure the soil is slightly acidic. Try adding more phosphorous in the form of bone meal. Make sure you are not pruning at the wrong time.

I have a 10 year old magnolia that has spread too far, too low and wonder if I can prune it by taking a whole bough off?
I take it your question about "young" is in reference to the article referring to pruning young trees. Since a magnolia can live over 100 years, a 10 year old tree is still young, and you should be able to prune it. If you have any doubts about your specific tree, you can have a certified arborist stop in and take a look. Here's an article that will give you a primer on pruning: http://extension.oregonstate.edu/linn/sites/default/files/pruning_pub_handout2012.pdf
I just purchased a Magnolia tree. My son loaded it on the back of his truck and it did not survive the ride home. The trunk of the tree snapped in two. Is there anything that can be done to save it? Can we splice it back together? Please help! Thank you.
Unfortunately, there is nothing that could have been done. Damage that extensive is not repairable. I am sorry.
The leaves of my magnolia tree have turned black. Is this mold? How do I fix this? It is a fairly young tree. Part of the landscaping for my new home.
I would treat your Magnolia with Neem oil.
Here are some links to help you.

I have had this tree for 10 years. It is finally about 10 feet tall, but it has never bloomed. What am I doing wrong?
Was your magnolia grown from seed by chance? If so, you haven't done anything wrong - it can take up to 10-15 years to bloom.
Does your tree look healthy?
Do a double-check on the care of magnolias by reading the following article - is it getting the sunlight, water and fertilizer that it needs?

Has this tree been in the U.S. long enough for it to be a host for insects? I am wondering if I need to plant some other plants to feed the birds around here, as I have heard bad things about the impact of non-native plants on birds.
The star magnolia was introduced in the United States in 1862. Healthy star magnolias are usually pest-free, but its twigs and leaves can succumb to infestations of aphids, scale insects, spider mites and leafrollers. I have read that star magnolias produce seed pods which feed the birds:

I have a magnolia tree that is 5 or 6 years old and stands about 15 ft high. I noticed that the leaves seem to be thinning out, then noticed that some of the branches are bare. The bare branches are dead, as they snap off easily. At first it was just one branch near the top but now several branches throughout the tree are also bare and seem to be dying. Why is this happening and can I save this tree?
I would still consider your tree a fairly new planting. Sufficient watering needs to be maintained for your tree. I would prune up any dead material on your tree and water on a regular basis. Wait and see is my best advice.
Here is an excellent article about growing requirements of a magnolia tree.
