This picture shows the corner of a cold frame, and an unprotected bed just above it. There is a patch of lettuce at the left of the above bed, and although the lettuce may be alive, it is not worth salivating over.
Surprisingly alive, but barely
I am surprised that the unprotected lettuce has not turned to mush, as a month ago we had a low of 13 degrees, just had a recent 15 degrees, and last night was 18 degrees. I may dig up the lettuce to repot to the porch for some recovery time before replanting to a cold frame.
Cold frame, 1/19/12
But with just a single pane of glass on the cold frame, this lettuce looks delicious. Pickable in fact. In time for a trip to daughter Emily's fridge tomorrow.
