sections of my viburnum hedge are turning brown and dying. Other hedges in the neighborhood area are also suffering from dead leaves and branches. Don't know what to do, should I cut off all the dead branches I live in Orlando. FL
Viburnum Hedge Turning Brown

This could be due to a few issues.
Viburnum can be susceptible to Armillaria root rot, Botryosphaeria canker is a fungal disease that causes leaves, even entire branches, to wilt and die.
These links have more information.
I would suggest also taking samples to your County Extension Office. Since multiple gardens are effected.
I'm including a link to locate your nearest office.
