I was scrambling this morning to protect my little cabbages and collards. It was in the upper 20’s and they did well over night in their plastic water bottle greenhouses but then the wind picked up and when I checked on them mid morning they were all uncovered. After a couple hours a few of them looked a bit windblown so I searched my cupboards for glass bowls. A quick search online told me to vent them with a stick during the day. I didn’t want to cook them under glass!
It’s late afternoon and I just checked them. Looks like they survived the day. As they get shaded by the barn I’m moving the stick so they are protected from the cold air overnight. Expected low 19 degrees F. Brrrrrr!
