Typically between October 8 and November 12, depending on the station; the median is October 22. Plan fall crops back from your own station's date.
What do "typical" and "safer" mean?
With the typical (50%) last-frost date, half of years still have a frost after it. With the safer (10%) date, only one year in ten does. In fall it's the other way around: the safer date is the earlier one.
