We already have been down to 41 F (5 C) twice. This temperature was
in a part of Lexington, KY that is 1070 feet above sea level. Some of the
Maples are starting to turn, as are the Dogwoods. The Dogwoods have
started to shed their leaves, but I think that low light intensity and
mildew have caused this more than cold.
