Cold Frame update - Late December 08

It’s almost the end of December, the 27th actually and I finally got out to check on the health of my romaine, lettuce and radish plants. They reside in two small cold frames in my front yard and would no doubt be complaining about the cold if they were able. The mean temperature for this month has been two degrees lower than normal and that’s a lot!
I noticed some of the larger plants in cold frame #1 show evidence of tip burn. This was caused by their coming in contact with the glass on days that were below freezing. Otherwise, they are in good health. The plants in cold frame #2 are also good to go, just a little smaller due to them get planted after the ones on frame #1.

Two conclusions I’ve come to regarding this effort are; one, that even though plants will grow during the winter, they do so slowly. And two, I need to consider a much larger cold frame if I am to have anything worth harvesting. Eleven square feet (the inside growing area of both frames together) is not enough to produce enough to feed one person. I will need at least sixteen square feet to accomplish this. So, that will be my next project this coming early spring. I am in the planning stage at this time.
