Many of my pittisporiums ar slowly dying, one branch at a time. What could this be and what should I put on them.
We have sprayed them with Neem oil but so far the leaves and branches are still slowly turning brown. What else should we do?

It is impossible to dianose and make recommendations without knowing more about the growing conditions and your soil and water management. Neem oil is not a cure-all and in some cases it is not appropriate treatment. Wrong dilution rate can cause burning of foliage.
Look first to water management, too much or too little? Too little is most common in cases of decline and die-back. If the plants have adequate irrigation, then consider fertilization and mulch. There are insect pests to consider.
