In order to get information about pruning or caring for my Magnolia tree, I need some information on how to identify it so that I get correct information. My tree flowers in early spring with large beautiful blossoms and when they die and fall off, leaves appear and they fall off in the fall/winter. It stays leafy and beautiful all summer. It is about 6 years old and about 14 feet tall and it looks strong and healthy. My problem is that the lower branches are 4 inches off the ground and they extend about 4 feet out from center all around. I must crawl under there to trim the grass and would like to know if I can cut some of the lower branches off so that I can put a push mower under to cut the grass. Will it grow into a tree or always remain like a big bush?
