I planted two Akebono Cherry trees a year ago sometime in November. They were doing well in the Spring: flowering and then beautiful green leaves emerged. But later this year starting late July the leaves started to wilt with brown edges around them. Now it's November, the trees still have their leaves but they don't look healthy. PLEASE HELP! We live somewhat close to the Bay in Marin County near San Francisco (zone 9). The soil is heavy clay but I amended it and planted the trees on raising beds. I was trying not to over water it but this summer I had to because we didn't get any rain. One tree is by the house another one is on the lawn though. I also have Kwansan tree and it's doing very well. I attached the photos. Thank you!!!
