I certainly agree with the importance of temperatures, but am not familiar
with
any classified Heat-Zones. Can you tell us more? I think Linda Mann is in
Zone
7 Tenn., as I am in Texas but I suspect there is a huge difference in our
growing
conditions. I personally always suspect warm and sometimes hot night temps
over an extended period of time kill more plants than the cold temps during
the
winter.
