the second thing that we did was a thicker piece of plastic at an angle, this is over the broccoli and the carrots. we also put this over an open bed and i am hoping to plant a batch of lettuce and spinach in that but i am not sure if it will germinate in the cold. i feel like everything we do is an experiment.
we also have two beds that are under recycled windows. this has been our most successful way of covering the beds in the past, but it is hard to lift them up without the snow falling
