Dana, where in the world did you find such detailed information on soil
temperatures? Because of the usual late winter/early spring damage to
some cultivars, I've always been interested in this kind of stuff too.
And I suspect it was even warmer here last winter than where you are.
All of the "southern wobbles' of the jet stream hit their southern
extreme well to the west of us so we escaped all late freeze damage for
the first time I can remember in the 35 yrs I've lived here.
I remember running across this kind of detailed soil temp info when I
did the search for Reemay and all the related plant bed covers, but
haven't seen it elsewhere.
<This is a topic I have always been very curious about so, I did a
search and
discovered that our ground temps only dropped below
40 @ 2" depth 25 times
last year, all in January and February. The ground
temp @ 2" only dropped
below freezing twice last year. At 6" we dropped
below 40 12 times and
never got below freezing.
