When I was growing up, I often visited the Central Experimental Farm in Ottawa, Ontario. I have fond memories of huge draft horses, grain fields, and flowers. The farm exists to develop new varieties and systematically discover the best techniques and crops for the Canadian climate.
My “farm” is tiny, but I’m trying to take a scientific approach to it. I have researched plant varieties and growing techniques in an attempt to find the best, most sustainable way to feed my family organic food grown right in our own backyard. I am planting an enormous variety of plants (about 100 different cultivars) to see what works and what doesn’t. I have tried to choose the earliest cultivars I can find because of our short season. In many cases I have more than one variety of a particular vegetable – I want to know what grows best. Naturally, this process of experimentation will take years to bear fruit (pun intended). Fortunately, if I keep track of my results, other people can save some of the same effort.
The square foot method makes this easier because each one-by-one-foot square can be planted with a different vegetable. So, for example, I have usually planted one square of each variety under a plastic cover and another without.
So far the plastic-covered seeds are winning. My turnips, mustard greens, radishes, spinach, lettuce, cabbage, kale, basil (!), and kohl rabi have sprouted under plastic covers, but only the mustard greens have sprouted in the open air.
I am also keeping very careful records of what I have planted, planting dates, germination dates, and even soil temperature. Our average last frost date is officially May 30th (perhaps creeping earlier because of climate change), and our first fall frost date is supposed to be September 15th. With only a little effort, I think it should be possible to push those dates in either direction by two weeks to a month.
Every garden bed is a little bit different, of course – more or less sun, more or less shelter from wind, slightly higher or lower elevation. My lot is quite flat and uniform, which is unusual in Yellowknife, so the variation between beds isn’t extreme. This makes it easier to garden and more consistent for experimentation. I have also filled all my raised beds with the same soil mixture, which eliminates another variable.
Slowly, but surely, I am trying to collect Yellowknife garden lore. Gardening is a popular hobby and I am constantly surprised by the things I discover when I ask people. There isn’t anyplace to look to find out whether chives will survive YK winters, for example (they will!), but there should be.
Everyone says you can’t grow much food in Yellowknife. They are somewhat correct. There isn’t enough arable land here to grow a lot of wheat or soybeans, for instance. However, I am increasingly convinced that, on a family by family basis, we could grow a significant percentage of our food here. The payoff for this is enormous: zero petroleum used in cultivation, zero petroleum used in processing and packaging, zero petroleum used for transportation – to produce organic, fresh, healthy, wholesome food. Even if we can only supply 10-20% of our needs, we should be happy to reduce our greenhouse gas footprints accordingly.
