I've never used a cold frame before. I planted it today with cold weather greens that should be OK down to about 30*F. Our weather is so balmy right now, but it will drop during this week. The frame is in a very sunny placation, so a few days of of sunlight should warm up the soil well. I'm hoping it will be full of salad greens soon.
Seedlings transplanted into the cold frame:
Parsley
Lettuce, Rouge d'hiver and Black seeded Simpson
Escarole, broadleaf
Kale, Tuscan, Winterbor and wild mix
Broccoli, Blue wind and Marathon
