80 degree temps in March for Michigan is unheard of. My Magnolia tree bloomed a month earlier than usual. While in full bloom, we experienced a hard freeze. . . . within one day all the flowers turned brown and look dried up. (Not just brown on the tips, they are totally brown. ) It has now been a month and they have not fallen off, and a few green leaves are trying to come through, but my tree looks terrible. What should I do to help it, and will it ever be healthy looking again? Thanks- Concerned in Michigan
Unusually cold weather can damage developing buds. So if it suffered from any cold damage, the tree may need to be pruned. Simply remove the dead brown leaves/buds. The tree should regrow its leaves though flowering may be inhibited some this season due to the cold damage.

Magnolia flower buds attacked by "pests" and destroyed them before flowering. The buds darken and simply drop off and appear to have been attacked during the autumn/winter. How to treat/prevent?
Have you seen the "pests"? It could be due to the wonky weather instead. Most people experienced a fairly mild winter, resulting in early budding of many trees and plants. This was followed by sudden cold spells, which could have possibly caused damage to these buds. This too would cause the symptoms you are seeing.
Should I trim my magnolia bush? It is huge and the bottom branches are very close to the ground, but large in size. I actually wanted a tree, but bought a bush instead. I just want to know how to care for it.
Yes, if it has gotten unsightly, you can prune it to your desired appearance. Just take no more than a third of the plant at one time.
I have an infestation of scale on my 2 magnolias, a bay tree and an acer. The bugs appear on the stems and branches and have secreted a white substance which appears like a sticky white cotton wool. I have been blasting them off daily for about a week with high pressure hose, but they return but seem to be less daily. Should I just carry on with my treatment or is there an easier way??
Hose down the plants and then treat them with neem oil. It is both safe and effective against these pests. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I have a five foot wall about 3 feet from the magnolia tree. Now, the leaves are turning yellow. I wonder if there is any relationship between the wall and the tree. The garden center told me it was from the concrete leaching??? I don't know if he is correct.
That could be possible, but only if the wall is relatively new, say just a few years old. If it is older than that, the chemicals in the concrete would have leached out long ago and be gone.
There are many things that can cause yellow leaves on a plant. This article should help you get some ideas on what could be affecting your tree:
I have a Japanese Magnolia tree that is infested by some type of fungus, I believe. I was told that they were mealy bugs, but after doing my research, it doesn't appear to be an accurate assessment of the problem. They're oval in shape and beige in color. The inside part of them are mushy, slimy and pinkish in color. My tree's barks/limbs have all turned black, to include my deck. The liquid, which is secreted from this fungus, is very sticky and dries up black in color. So far, I haven't found any pictures online to describe what has infected my tree and I'd sure hate to chop it down. Your help would be greatly appreciated.
I think the culprit here is scale, though mealy bugs is naother possibility. It also sounds like the tree has sooty mold (the black you are seeing), which is actually an indicator of the pest infestation. Many times these pests are too small to see, but they can be damaging. The stickiness you notice is honeydew, which they secrete. I would recommend treating the tree with neem oil. This will treat both the pests and the sooty mold fungus.

Our Tulip Magnolia has a gall, yellow to light orange with lots of ants around. Can you, please, tell me what it is and what treatment to use?
Oftentimes, galls can be spawned by insect pests, like aphids. If you are seeing ants, this would be a clue that aphids (or similar sap-sucking insect) are present, as they are attracted to the sticky residue these pests leave behind (honeydew). You can treat the tree with neem oil to get rid of the aphids, which in turn will get rid of the ants as well.
