Hi, Almost all of my deciduous trees have white powdery mildew on their leaves. It came on very fast and spread quicker than I can believe. Of the trees that have it, they have lost almost all of their leaves. I have applied Daquinil 3 in 1 fungicide, both proactively during the season, and now trying to get rid of the mildew and ensure the trees are going to winter alright. I am new to bonsai, I live in NJ USA, and we are transitioning from summer to fall right now. Thanks.
