Q.What Is Wrong With My Mock Orange Plant?
My small healthy mock orange was goin good along nicely when all of a sudden the leaves on several of the branches withered died and go crunchy. It seems to be happening one branch at a time with no warning, like wilting. I was told it was a fungus and to spray it with neem. That has not stopped the branches from turning.

Keep pruning out the dead wood; maybe you can stop its spread. This article should help narrow the disease:
