My Magnolia tree used to have beautiful flowers. Now the buds start beautiful, but before the flowers open, the tips turn a rust color and the buds never open. What is the solution? I water twice a week.

How have the temps been around bloom time? It sounds like they may be suffering from a bit of cold damage. Unfortunately, there is not much to be done for that.
If cold has not been a problem, make sure that when you are watering, you water deeply and at the perimeter of the canopy of the tree, not at the trunk.
