Yesterday I realized a disease has seriously harmed my red twig dogwood. It\'s white powder that seems to extend up the branches from the roots. Some branches seemed completely dead with all of the leaves dead. Some branches with less white powder seem like they are dying. I started cutting some of the totally dead branches. Is this a form of powdery mildew or something else? The pictures I found online for powdery mildew didn\'t seem as extreme and all encompassing as this.
