I was asked to elaborate on the construction of our row covers, and having considered doing a post on this subject in the past I was finally encouraged to do so. Season extending row covers allow us access to fresh salad greens at least until early January and often all year depending upon the weather. Regardless of the amount of snow received, if diligent in keeping the row covers free from snow, I am also provided with a place to plant greens, onions, brassicas and other cold hardy crops in the very early spring.
We also have a few cold frames and will be constructing more in the future and although they do have some advantages over the covered rows they cannot cover the amount of space needed and are also not as versatile especially in the sense that they cannot be easily removed when no longer needed.
It has been my experience that many winter greens, especially less mature (smaller) ones, can survive numerous freeze and thaw cycles. The trick is to provide them with adequate protection from the elements as the, wind, rain, and snow will take their toll on the crops long before cold temperatures will.
The design I chose for my row covers is simple yet effective, easily put up and just as easily dismantled and stored away for the season. Our garden rows are approximately 4' wide and anywhere from 10-60' long. I use 1" poly irrigation pipe for the tunnel frames and 4 mil, 10' wide plastic for the covers.
The pipe is cut with a hacksaw into 8' 4" lengths, to allow for taller growing greens such as Swiss chard and certain brassicas.
A length of rope is staked to the ground at each end of the row as well as being securely looped around each individual pipe in order to prevent them from sliding back and forth.
To further strengthen the pipes a piece of rope or twine can be attached to both sides of each hoop in order to allow it to handle more downward pressure.There are a few issues with this type of season extension. The snow can accumulate faster then you can remove it and the structure may collapse under the strain. While shoveling the snow off it is easy to tear the plastic. I find that a piece of duct tape attached to each side will fix any rip and often wait until summer to repair the tears as I am able to dry the plastic in the sun and this really helps the duct tape to bind with the sheeting. Some of my tape jobs have lasted over 3 years now.
Although row covers as season extenders take some effort, the choice has been made to use them as it affords us the ability to procure fresh produce from the garden much longer then otherwise possible and also fits into an ongoing goal to provide for ourselves. As our quest for food self-reliance progresses, we find ourselves increasingly reluctant to consume food from sources other than our own garden. The availability as well as the quality of the produce offered in the supermarkets is most disturbing and I would just as soon not have to wonder what is in, on, or being done to our food. Below are a couple other posts I've written regarding cold weather gardening.
There Is Nothing Like Salad Fresh Out Of The Garden In January
Winter Greens



As far as ability goes, my horticulture skills are average at best and certainly do not achieve "green thumb" status, so I must use any means necessary to achieve my goals. Fortunately, I do excel in one area that is most helpful when it comes to growing ones own food, I am persistent. My secret to a great garden harvest is to plant a lot more than I will ever need so that no matter what Mother Nature throws my way I will surely have enough. One for germination issues, one for the bugs, one for the voles and field mice, one or two for the weather and the rest for my flock and I... Perseverance!
