Our tree has been slowly getting brown edges on its leaves.
This is likely caused by a lack of water. I would increase water to the tree.
My magonlia tree is over 5 years, and no blooms at all. It is growing tall and green but no blooms. Is it true it is a male and bears no flowers?
Magnolia trees do not have male and female trees (though some other kinds of trees do). Both the male and female parts of the flower are contained on the same blossom.
If I had to guess, I would bet your magnolia is planted in the middle of a lawn that gets a lot of attention, especially in regards to fertilizer. Lawn fertilizer is high in nitrogen, which makes for lots of green growth but few flowers. If there is enough of it, it can actually stop a plant from blooming.
Try adding some bone meal (or other phosphorous heavy fertilizer) around the tree at least a few feet from the trunk. This will help offset the nitrogen. Also, if possible, try not to use lawn fertilize under the magnolia tree.
This tree is over 5 years old and it hasn't given one bloom. Why?
Have you fertilized? The soil could be lacking phosphorus, which is responsible for blooming. Get a soil test to know for certain. In the meantime, it wouldn't hurt to go ahead and add some phosphorus-rich fertilizer or bone meal to the soil to help encourage flowering in your tree.
What is the proper watering cycle for magnolia trees?
Once they are established, magnolias typically do not need to be watered unless you are experiencing drought conditions. Right now, much of the country is experiencing drought conditions, so you may need to water.
If this is the case, once a week is good. The water should be done so that it covers from the trunk all the way out to about a foot or so beyond the edge of the tree's canopy. 2-4 inches of water should be put down at each watering.
Watering is best done in the early morning or early evening.
I have two saucer/tulip magnolias in my yard. I would like to know soil requirements and best time of year for pruning?
Why does my magnolia bush have yellow leaves?
The tree is stressed from a watering or nutrient issue or pest of some kind. Check the soil for excessive moisture. You may need to improve drainage to the area. Also, get a soil test to see what, if anything, is lacking and fix as necessary. Finally, check the tree carefully for signs of pests. Neem oil is an effective treatment for most insect pests.
When and how should I prune a magnolia shrub (it's not a tree but a small shrub - or at least should be!)?
You can prune it to your desired appearance. Just take no more than a third of the plant at one time. This article will help: https://www.gardeningknowhow.com/ornamental/trees/magnolia/pruning-magnolia-trees.htm
