I finally got out to the garden today to check on the green stuff growing there. Even after Tuesday night's low of 13, stuff was alive. It wasn't all necessarily happy, but it was alive.
The lettuce did fairly well. Some of the plants looked bad, but most looked pretty good. The cabbages are ok, but a bit droopy.
The Red Russian and Dwarf Blue Scotch kales, which had the same amount of protection as the lettuces were wondering what all the fuss was about. "Cold? You mean this fine, brisk weather?"
The brussels sprouts are under only a row cover, with sheets and tarps thrown over for extra protection on the really cold nights. They look droopy when viewed through the row cover. After tomorrow night, when the low is forecast at 16 degrees F., the weather warms a bit (lows in the upper 20s) and we'll see how things are doing with a bit of recovery time.
