Growing a Winter Garden

Posted by Thomas, from A Growing Tradition Blog.

Eat local, organic, in-season foods
- that's a mantra that may be difficult to follow year round, especially if you live in an area located within climate zones 1 through 7. Where I live, in zone 6 northern Massachusetts, our winters often prove long and frigid. Those wishing to buy organic locally grown produce in November will find that most of our farmers markets have closed for the season at the end of October. And the few farmers here who do choose to grow vegetables during the winter months may not always practice sustainable methods, since adding supplemental lighting and heat (which consumes significant amounts of fossil fuels) to a commercial greenhouse operation may be perceived as the only viable means to ensure a timely harvest. The alternative would be to buy organic produce at a supermarket. But in the dead of winter, this would not be considered local, in-season or sustainable.

This reality begs the question - as someone who wishes to follow this "eat local, organic, in-season" mantra year round, am I limited for 6 months out of the year to what's stored in a root cellar, processed in a jar or bagged in a freezer? Or is it possible to add some fresh variety to my local diet during the lean months by starting a low-tech, low-energy consuming, organic winter garden, while at the same time lessening my family's dependence on produce that is shipped in from California and foreign countries? (Packaged organic salad mix, for instance, is one of the most energy-inefficient and costly veggies that one can buy at the supermarket.)

I will admit that I have a fascination with growing and harvesting food during the winter months beyond just the need to eat local, organic and in-season food all year round. For starters, I appreciate the fact that this practice has had a long and rich history, particularly in Europe, and the stubborn Luddite inside of me wishes to preserve this tradition. Ultimately though, for the die hard locavore (which I am not), it does not get any more "local" or "in-season" than growing your own winter crops. Nor do you have to rely on a governmental agency to tell you whether the carrot that you are consuming is organic. And finally, using low-tech winter gardening techniques ensures that your practices are sustainable.

winter bed inner layer
Depending on where you live, your winter veggies may require an extra layer of protection during the coldest months. An inner layer of fabric row cover can help to increase the nighttime temperatures inside of your hoop houses by a few critical degrees.

I am a huge fan of farmer and guru Eliot Coleman, best known for his writings on winter gardening. His Four Season Farm in zone 5 Harborside, Maine specializes in growing food year round using only low-tech, non-heating (and in some cases, minimal-heating) elements. Coleman's technique relies upon, among other things, choosing the right varieties of winter crops, succession planting on specific fall dates, and a couple added layers of protection during the harsh winter months. The goal here is not to create an high-tech artificial environment in which to grow anything and everything, but to use low-tech and sustainable methods to give traditional winter crops the added protection they need to survive all winter long in zones 5, 6 and 7 and to extend the growing season by at least a couple more months in zone 4.

Snow
Hoop houses must be strong enough to withstand the heavy snow storms and winds of winter.

So grow a winter garden if you'd like to add some fresh variety to your local, organic and in-season diet during the cold months. Here are some tips on how to get started:

1. Read about Eliot Coleman's Winter gardening techniques. Coleman offers a great deal of information on which winter crops to grow, when to sow them and how to protect them from the elements. His book, "Four Season Harvest: Organic Vegetables for Your Home Garden All Year Long" is a great place to start.

2. You will need to offer your winter crops some form of protection from the elements. There are many hoop house designs available via the internet that practically anyone can build. Personally, I utilize mini hoop houses. You can read about how I built my mini hoop houses at here or go to http://www.agrowingtradition.com/2009/10/building-mini-hoop-houses.html.

3. Familiarize yourself with the hardiest of winter crops. Here are a few (some varieties are hardier than others): leeks, carrots, green onions, lettuces, bull's blood beet, a wide variety of Asian greens, spinach, radishes, chard, kale and wild greens like wild arugula, mache, claytonia and minutina. You will be surprised by the amount of fresh greens you can produce during the winter months.

4. Finally, just because none of your neighbors grow a winter garden doesn't mean it can't be done! Believe that it can be done and seek advice from local gardeners and bloggers who do! Practice makes perfect and soon, your lean winter months will seem shorter and shorter.

A picture is worth a thousand words so here are photos of some of my zone 6 winter veggies:

I love this....we've just moved, so a winter garden isn't in the cards this year, but perhaps next! I loved all the freshness from this past summer's garden!

This is exactly what I needed. Thanks for putting it in front of me and giving the info to begin. I have wanted to know. I am new to gardening in northern New Mexico which is Zone 5 and was wondering. My one disappointment which has nothing to do with your post is that it is mainly greens. It does answer the question though of why this is what we get in the CSA box and I find at our Farmers Market which does not shut down, but definitely has fewer vendors.

Thank you for the post. I currently live in a HOT arid climate, but will file away this information for the day we move back to the Northeast. I would also like to read Coleman's book, so thank you for the reminder! Good luck with your winter garden, and if anyone knows some tricks for growing veggies in a desert (with desalinated water), I'd love to hear from you!

Amazing! I've just started reading Coleman and ordered his other books. I too am hooked on the idea and am starting to scheme for next year.

What beauty! I just posted some photos of my winter harvest here in Maine. It's my second season over-wintering greens, and I hope to expand. Thanks for the inspiration!

I will never complain about growing food in winter. We are very lucky here our winters are very mild, but frosts can kill plants pretty quickly. You have inspired me to try and cover some of my garden.
Well done.

I keep trying to grow a winter garden, but then since my garden is shady my stuff doesn't mature as fast as I'd like. Then I run out of space. I think when I add a few more beds I'll start leaving a few beds in cover crops spring/summer just so they're ready for fall crops.
