Congrats on covering your bed with the plastic. It always amazes me what a difference it can make to keep the crops from total damage. I do this with my raised beds in early spring to start my cool-season crops here in western, N.Y. I have been gardening for over 50 years and I am still learning and experimenting with new ways to keep on growing. Right now, since it is December, I will start growing microgreens in my plant room again. I still have Rutabega in the garden but I think I planted the seed way to late to get a winter crop. Always learning. Great job on your garden.
