Japanese maples did not loose their leaves over winter
I believe that the Japanese Maples in my yard typically loose their leaves completely in the winter. I know that I have pictures of them in ice storms in the winter with no leaves. This year they have kept their leaves throughout and they are still rust colored and hanging on. Could you tell me if this is an usual and why?

This is occurring all up the East Coast. It is caused by the abnormally long warm fall that suddenly got bitter cold. Many Japanese maples as well as many other species were not able to transition into dormancy normally. They should all be fine. The dead leaves should fall off when they put out new growth in the spring.
