My 20 year old magnolia was damaged in an ice storm. I live in Northern Indiana and only have blossoms on the tree for a two week period in April-May. A large branch and nearly one fourth of the tree was ripped off in the storm from the heavy ice that coated the area. The tree is very lopsided now. Do I dare prune it heavily after it blooms, cut it down, or leave it alone. The tree was over 20 feet in height and had many branches of large pink blossoms. There are many buds on the branches for this year, but it looks pretty ragged. I am not sure what to do.
