So my spinach, bietola swiss chard and trevisio radicchio all over wintered successfully in the cold frame and are now ready to be transplanted to their permanent raised beds. Again I'm really surprised how well the cold frame worked. We've had the worst winter in recorded history here in PA, and the cold frame was able to shield the greens from any permanent damage. All the greens you see above were sown in October of 2009. I regularly watered them once spring temps began to rise so they wouldn't dry out inside the cold frame. The one thing you have to remember is that the cold frame doesn't let much rain water inside, so it's up to you to either remove a lid from the cold frame once you expect rain in your forecast.
