My sprouts that froze had been enjoying nights in the high 30s and the sudden plunge to below ten (as in single digit temp) is what did them in. It was bitter and mean, that night!
But all is well now. And I did get some planting done after all as schedules changed, but mostly potting up lettuce that I'd left in the jugs. I did do four more of my little border clay pots, these from wintersown chamomile (German this time) and thyme. But no pictures cause by then I was bushed and hongry!
