Some of my evergreen shrubs have brown, dead branches. This is seen mostly near the root and underneath more healthy foliage. Is this fungus or some kind of mineral deficiency?

This happens because not enough light is reaching the lower limbs. When you trim the shrubs, trim them so that the sides angle in just slightly. This will allow more light to reach the lower limbs and prevent them from dying.
