Frost

The question for today was--Should I bring my plants inside?  The forecast for the morning of September 24 was for frost in my town of Franklin in the western mountain section of North Carolina.  This could be a record-breaking low.  Usually we make it into October with no really cold weather.  The neighboring television stations said our low was 32, but they never are close to what the town has.  Our thermometer was at 41 with just a bit of frost on the roof.  There seems to be no harm to all the flowers I didn't bring inside. The forecast is for warmer the rest of the week.
