Fall Season Powdery Mildew?

[thatguy]

Hi All,

Recently spotted some of what I believe to be powdery mildew on my maples. I thought at first it was just hard water spots but now I think it is mildew. It affects a few leaves on some palmatum seedlings, a few leaves on a little koto hime and a bit more widespread on a dwarf palmatum.

Is this common in Fall do to the increased dew in the mornings? When I water I don't get much of the foliage wet. Should I treat them with copper fungicide or is it close enough to leaf drop to not be a concern? See attached and thanks!

I wouldn't worry about it.

Mine is doing something similar and I’m stressing out

That's normal, nothing to worry about.

I like not worrying! Anytime I'm able to "not" worry about something is a huge victory in this day n age. Thanks for the reassurance
