Today's Post had a garden column in which the writer bemoaned the fate of his fall-planted fava beans, but was glad he hadn't built a hoop house because the recent cold weather would have been too severe anyway. Caused me to wonder how the White House garden survived the cold. In past years Obamafoodorama has noted the hoop houses surviving snow, but the cold might have been too much.
On a personal note, my wife harvested the last fall-planted (transplanted) kohlrabi just before the single digit weather. Still good.
