Actually, I planted to the coldframe 10 days ago. But it was a really long shot, and yeah, the 10° nights that followed whacked the liddle bit of lettuce seeds that I stuck in the ground.
Today was quite another matter. There’s still a lot of chanciness involved—we’re zone 4B, and wintry weather isn’t done with us yet. But today I stuck my gunboats in my pink (hells yeah) barn boots, tucked seed packets in my shirt pocket, and put in a half-row each of maché (though using last year’s seed—is that a mistake?) and lettuce (Burpee’s Green Ice).
The good news: When the back porch thermometer said it was 52° outdoors, the thermometer in the closed coldframe said it was 72°. Scott, the coldframe builder, has been tinkering with it to get it truly windproof, and I think he just may have succeeded. We’re not having a sunny winter (we did last winter! I swear!), and that’s not helpful. The coldframe needs sun to get really warmed up. Still, when it’s holding heat that well, it just might make it through the nights in the the teens that await us here in Squirrelyville. This second planting has a much better chance than the first did.
