Ughh... got lazy... lemon zest heavily affected by powdery mildew

[savemejebus]

Did not really pay attention this year. Lemon Zest put out a ton of flowers - tree fully loaded. Just today walking by noticed not too pretty of a sight - appears to be full of powdery mildew. I don't want to spray sulfur at this point as a lot of flowers are open/fragrant right now. Is there anything that can be done or just hold by breath and wait for the flowers to run their course?

Spray the sulfur right now but it’s probably too late. Should have been done when the panicles and flowers were emerging.

Lemon Zest is horrific when it comes to PM. Zill won’t even be grafting it anymore because of how disease prone it is.
