I planted a resistant variety, it is planted in an open area of my yard w no other shrubs/trees around it, so it has plenty of air. It is raked and cleaned up meticulously. I have only had it planted 3 years and (4 summers) and for the past 3 summers by mid July most of the leaves look awful and many have fell off. It is a Robinson. I am thinking of taking it out I am so disappointed w it. I did drench the soil w a fungicide this spring, it does seem better this year, but I can still tell its there. There is no way to spray a mature tree and reach all of it, not feasible for the average homeowner. Better to just toss it out now before it gets any larger I guess.
I am thinking of replacing it w a clump amur maple.
