Q.I Have A Dwarf Navel Orange Tree Whose Leaves Have Died Completely Just On One Side. The Other Side Looks Healthy.
I cut off the dead branches on the one side, but of course they remaining ones stem from the main trunk. Not sure what to do at this point. Thanks. Pam

Your tree is stressed from insects, fungal disease, old age, or environmental problems. Was the good side shading out the dying side? If so, prune to keep the canopy open.
Here are some causes and your options:
