We've read that it's important to keep the plastic from touching the leaves so that the condensation won't freeze the leaves to the plastic. Our row covers float over the large raised bed about 15 inches from the box and about 12 inches over the narrow bed. Hopefully this will be enough to keep everything protected from both the harsh winter and the moist plastic.
