I had some sugar maples near by but on different irrigation systems do fine but one that was in the sun with a spray irrigator didn't. One parrotia in more shade did good but the sunny one didn't. We had our usuall perfect October with cold nights in the 30s. Followed by sunny warm 50 and 60sF afternoons. You are right about microclimes but I have planted based on those variances. We irrigate all late summer to overcome the dry airs we have in Aug and Sept. The plants seem to enjoy the irrigation. The trees that were planted in our lawn did fine (mature specimens) that only had once a week irrigation 1 to 2 " soakings. Thank for the ideas.
This is one acer sacc. that had good color and leaf shed. I have about 9 sugar maples and only one did the no color change.
