Diseased Outside Bushes

In the corner of my yard, I have a bushy hedge that grows from the top of my retaining wall with branches that cascade down the wall to cover it. Recently I noticed that a few of the branches were turning brown. So as I went to snip them off and spray the hedge, I picked the long branches up and underneath was MAJOR discoloration. The underneath root area is pretty much completely blackened and brown, and a white dusty powder was blown up. My question is: Do I need to completely get rid of the hedge? I love it and want to save it if I can.

Yes, I would trim it all back and then treat it with a fungicide. The white powdery stuff is powdery mildew. Here is more information that will help with treating it: https://www.gardeningknowhow.com/plant-problems/disease/get-the-cure-for-powdery-mildew.htm ^[1]
