Quick update on the cold frame: after snow, blizzards and other March weather, we planted lettuce, mixed greens and green onion seeds in the cold frame today. It was up to 25 degrees Celsius in there today, only about 7 or 8 outside, so it is functioning. Yay! I’ll add a photo from this year when we see some growth.

Planted the rest of the cold frame today – spinach, radishes, mixed greens and carrots. Keeping our fingers crossed.
