First average killing frost -- NOT


On Aug. 19 I calculated the first average killing frost for my area by going to the website of the National Climate Data Center. The date I came up with was Nov. 12, yesterday.

Although we have had at least two nights as low as 31 degrees, we have not had a true killing frost for which 28 degrees seems to be the magic number.

Impatiens (above photo) are a sure-fire measure of a killing frost. The bright blooms fold up and drop off with the first hard freeze. These are probably not long for this world.
