I haven't posted anything in a while, and I apologize that I don't have any pictures (I forgot the camera in the house) but I do have an update. We had three types of vegetables in the two cold frames alive and well before winter struck. Swiss Chard, Spinach and Parsnips. I am happy to report the spinach is alive and well, even the sprouts that didn't have time to turn into full sized plants are still green. The chard looks dead. And the parsnips still have green growing crowns (the rest of the leaves look dead).
I have made a couple of observations this year on the subject of cold frame gardening.
2. In my case, the cold frames are in a pour spot in regards to sun exposure. They face south but the low winter sun gets blocked by the trees in our yard. In town, this might be unavoidable.
