Let’s start out with a bit of honesty, shall we? The four season harvest isn’t for wimps. Winter gardening —growing plants in temperatures below freezing to sub-zero, beneath plastic sheeting— isn’t a natural act. And although I enjoy a good game of woman vs. wild, sometimes winter gets to be a bit much around here. Shoveling decks, terraces, walkways and woodpiles is a lot of work. And now that I’ve added potager path-clearing and hoophouse roof-raking to the list, I’ve created quite a snow-removal burden. So why do it? Because the taste of fresh arugula and the smell of damp earth on a cold February day is —as the people at Mastercard say— priceless. And I think a jump-start to the short, northern growing season is worth a little extra work (OK, so it’s a lot of extra work).
Over the past three years —cooking more at home and experimenting in my kitchen— I’ve become more and more interested in four-season vegetable gardening. And although I haven’t made the leap to a heated greenhouse yet, I’ve found that with proper timing, I can keep some crops going in my hoophouses year round. Greens sown in late fall will germinate and then continue to grow (albeit much more slowly) throughout the short, cold days of winter. Tender crops are out of the question of course, but tasty root vegetables sown in early autumn can be harvested from cold houses straight into the new year. Seedlings require light to grow —10-12 hours of daylight is a good rule of thumb— so the sowing of seed is suspended during the weeks leading up to —and about a month and a half after– the winter solstice. But come late January, February and March —when the days are getting longer, and sunlight is getting stronger — I can begin sowing cold-hardy, late winter crops in my unheated hoophouses, for early spring harvest. Yesterday I planted a variety of greens in house #3 (arugula, chard, spinach, lettuce and mesclun mix), and I pulled spent crops and turned soil in house #1 to prepare for more planting (carrots, radishes and other crops) on my next free afternoon. If you are interested in learning more about the four-season harvest and winter vegetable gardening, I highly recommend Eliot Coleman’s books. And if you’d like to build a hoophouse of your own this spring (I now have four, with three currently in use) click here for basic plans. I’m hoping to upgrade to a larger, walk-in cold house this year.
Gardening in winter is all about science, but it sure feels like magic when you can reach your hand into sweet, sun-warmed earth on a cold and windy day. And it’s even more spectacular when you’re enjoying your own salad greens and root vegetables —harvested from an icy, snow-covered garden— at dinner in January and February. Winter pasta with fresh arugula, root-cellared onions and olive-oil preserved, sun-dried tomatoes —all from the garden— now that is priceless…
Here’s the potager, with house #1 and #2 buried by nearly 3′ of snow and ice. I still can’t believe they didn’t collapse. And yes, I shoveled them out all by myself. Sadly, Alfred hasn’t left Batman for me yet. I can’t figure out why…
