To get plants going through winter, I decided to construct some cheap low tunnels. I followed the directions in Nikki Jabbour's The Year Round Vegetable Gardener which is pretty similar to these instructions. Although, I don't use a sleeve for the PVC (small beds), and I instead have a piece of PVC to act as the 'spine' between my two PVC ribs. The spine is connected to the ribs with a #320 U-bolt. No collapse so far!
I also have some Super Hoops from Gardeners.com for my smaller bed. Even if you're not going to grow through winter, a low-tunnel can help extend the season. It'll let you start growing earlier and keep harvesting later. Certain vegetables, such as mache and carrots even get better with cold. Carrots, however, can just be covered with 6" of mulch. No tunnels needed!
Once the hoop tunnel is put together, you place a few inches of mulch, compost, or organic matter on top of the bed. This helps block out weeds while also improving the quality of the soil beneath it. More plant nutrients! Then the bed is ready to be filled with cold-hardy plants.
Here's my slightly frost-bitten Asian greens that I forgot to throw a cover on. They may not make it. They're now under both a row cover and a plastic drop cloth. Each layer of cover is said to move your growing zone one further south (although any more than 2 blocks out too much sunlight).
I think I should probably do denser plantings...
