Checking in on the winter greens mini-experiment. These guys have been through six weeks of up and down weather, balmy days well above zero (reaching 60-70°F/15-20°C on a sunny day in the hoophouse) , and many extreme freezing nights. So, how did it all do? The Bloomsdale spinach, uncovered (above), is fine, although after all that freezing and thawing, the taste and texture changes (good to eat, but probably wouldn’t sell). It wasn’t the plan, but this spinach can be trimmed back to see how new growth does in spring. The other beds, all brassicas (tatsoi, mizuna, arugula, mustards), left half uncovered, are completely toasted. Meanwhile, under a single layer of medium-weight row cover, arugula (below) is good, perky and quite tasty. Not the most extensive and scientific testing plan, but combined with the experience of harvesting through December and in mid-January, it’s a solid starting point for next winter’s goal of full-on, unheated winter greens production!
