I and two of my friends each acquired an Amagi Shigure in the fall of 2013. *Last year was the first full year for all of us and all of us experienced a similar problem. *All three trees leafed out fine in the spring but shortly after the leaves were fully formed individual leaves started dying. *The petioles on the leaves turned black and limp and the leaves gradually did the same. *The initial appearance was almost as if they were wet. *The leaves dried somewhat on the tree and then fell off. *The leaf loss did not happen suddenly but throughout the summer. *By the end of summer all three of the trees had very few healthy leaves (Iâ€™d estimate no more than 15 - 20 per tree. *Aside from the leaf loss all else seemed fine. *Bud formation by fall appeared quite normal at the nodes where the leaves fell off. *This spring all three of the trees leafed out in spectacular fashion. *Unfortunately all three are now seeing the same symptoms as last year. We all have planted numerous maples and the three are all obviously in different locations. *All are correctly planted. *Water certainly isnâ€™t an issue as this spring has been perfect and the last two winters have not had any extremes occurring both years. *In fact I donâ€™t think there were any real extremes either winter. *The leaf loss doesnâ€™t seem to follow any pattern that makes sense. *Leaves seem to droop at the tips of branches, in the middle of branches, towards the bottom, middle and top of the trees. *This spring certainly hasnâ€™t been unusually hot and a our weather in the Pacific Northwest isnâ€™t extreme. Iâ€™m attaching three photos of my tree. *One is the full tree (great looking!) and two show leaves that are turning black. *You may have to enlarge them to fully see the effected leaves. We would really appreciate any diagnosis you may have. *Iâ€™ve tried to search the Internet for Amagi Shigure issues with no luck.
