It's been a while since I wrote here. I've been getting little projects accomplished over the winter, but mostly doing research and preparation for the season. Obviously, the hoop house has been something I've been able to work on even in the cold weather. I was out digging up the beds in January and February. Even through the blizzard, during which by the way no snow accumulated on top of the hoop house because of the strong winds, I was able to continue working in the soil.
I've been keeping track of lows and highs in there all winter and the lowest temp recorded was I think around 4 degrees, but that was without using the row cover, a thin plastic fabric, which insulates the soil and keeps a warmer microclimate underneath. Once I'd planted, first small test beds in late January and then the first plantings of most crops in mid-February, I used row cover to add another layer over the beds to hold heat from the soil in overnight. During the sunny days I would roll back the row cover so the plants could get heat and sunlight.
