I've been looking forward to harvesting lettuce on Christmas Day. In the snow. Not much left in the frame now, but enough for a bowl of greens for the Christmas table. They were very fresh and crisp. I picked spinach, baby beet greens, escarole frisee and curly red lettuce. I also added some baby kale for color.
I think this is my last harvest of the season. Maybe what's left in the cold frame will wait until spring and regrow when it warms up again. I've heard spinach is good at regrowing in the spring. We have heavy snow coming tomorrow night, so I'll replace the tarp covering tomorrow and see how the cold frame survives its first winter.
