Do I need to give an annual/spring feeding to my row of arborvitae that were planted 20 years ago? If so, what would you recommend?

Mature trees are more equipped to resist disease, pests and fuller, dense foliage than younger ones, so fertilizing shouldn't really be a concern for yours unless it is beginning to show signs of stress. As long as it looks healthy, I would simply let it be.
