Parts of my veggie garden are still plugging along under the hoops. Ended up doing two beds that way (plastic over 1/2" bent pvc), and laid my cold frame over a third bed. Still getting lettuce, radishes, beets (too many), and carrots. Started spinach too late. Cabbages are getting some decent size, but about half of them are pretty eaten up by cabbage worms. Biggest problem is getting out there to water since it's dark when I leave and when I come home from work. I haven't been out there to see what these temps in the teens have done to things in the last few days.
This has been a lot of fun extending the year like this. Fresh veggies in December is a new one for me. The natural thing to do now is get stuff outside earlier next spring.
