Grandma is 96. She still lives in the house that she raised her 4 children in, along with numerous fosterlings along the way. She still gardens, and still produces enough to put away for the winter. When I went up to visit her in February, she was still eating her own carrots, potatoes and beans.
I asked her what her last frost date was, given that her house is north and east of Ottawa ( I was imagining a short growing season). The conversation went like this:
"Grandma, when is your last frost date?"
"I don't know"
"When do you plant your garden, then?"
"When the ground is ready to be worked" (a look at me here, suggesting I was a bit dense for asking)
"How do you know when it's ready?" (here I was hoping for some practical advice for my own efforts)
"I just know" (again, the look that I was asking very stupid questions)
She just knows. After a lifetime of growing her own food (a necessity, not a hobby or a fad or an experiment) she just knows. She composts as a common-sense understanding of what her garden needs, as well as a habit of necessity - once they took their garbage to the dump and were charged based on weight. Her garden is rototilled in the spring (now that my grandfather is gone, my cousin does it faithfully for her) so that the ends of last years crops get tilled under. She doesn't exactly rotate her crops, but nothing is really set in stone, so nothing necessarily gets planted in the same place as last year. She doesn't use chemicals - they are an unnecessary expense so why would she? She thinks her garden might be a bit tired these days, so she gets my cousin to add some manure from a local farmer each spring now.
She grows what she eats because that is what she has always done (as did her parents before her) and because why should she not? Why would she buy tomatoes from somewhere else when she could grow her own and then can them?
Granted, at 96 she is slowing down and so I've noticed that she is buying more of her food lately. There was a time when she would not buy things out of season, based on cost alone. But she also doesn't understand why on earth we would bring in vegetables and fruits from 'far-off countries', why we should expect to eat strawberries in December. It makes no sense to her at all. And while she was brought up on a farm, she has lived in town now for 80 years, so I am talking about a woman who has gardened in her back yard and whose beliefs have been formed by real life (and real economics) as well as practical experience.
But of course my (our) generation has been raised on strawberries in December and whole tomatoes in February and asparagus in November. Meat eaters eat fresh beef in spring and fresh poultry in winter, no matter when Nature intended for them to be fattened up. And regardless of how far we live from the sea, fish eaters want to be able to enjoy lobster and shrimp year round. My (our) generation associates food with stores - clean, displayed, packaged, predictable, year-round.
I am not advocating that you give up lobster or that you can only eat your steak during the late fall. I am not suggesting that maritime processing plants should close down during the off-seasons, that farmers should only earn income for half the year, or that hot house / greenhouse gardening is 'unnatural'. I definitely am not saying that you should feel guilty about enjoying what you eat.
I just think that we should think about it a bit.
We import a great deal of food from countries which have lax environmental laws (and so do you really know what is being sprayed on your conventionally grown food?), and as consumers we don't really know what happens to that produce between field and table. Even organically grown food has a cost - it must be transported, it must be harvested (usually by large tractors using oil in some state), it must be tended to by workers (often migrant workers with few benefits or rights), it must somehow make it to the store (organic gases to preserve it, perhaps?).
For most of us, there is little option but to buy our produce from Loblaws or Metro or Sobeys during the winter months. A one-bedroom apartment in the city is unlikely to provide enough space for a significant amount of food preservation or storage - even the freezers in apartment fridges are small. Those farmers markets that are open year-round don't often provide a lot in the way of fresh veggies. City dwellers that don't own cars also don't have the luxury to travel out into the country to buy seasonal products from farmers. We have evolved into a culture that depends on the fresh-produce section of our local 'supercentres'.
But I really believe that the produce that we get there isn't what we would ideally be eating or feeding our children. I also don't think that I am alone in feeling that most of what you buy at the store tastes terrible to boot. I also believe that, during the summer at least, we have a choice.
It takes little space and time to grow a seed into a tomato plant on a balcony. It may take a bit of reading and attention to grow a tomato, but one tomato often leads to many tomatoes and so suddenly you have fresh, delicious tomatoes for a few months. You may have enough to give your friends a bunch, and if you are lucky to have the inclination /time/ space, you can can/freeze / dry your tomatoes and enjoy them in January. It is not a big stretch for us to grow a bit of food. You will also likely enjoy your time with your plants - you might enjoy watching your tomatoes grow (cocktail or a coffee in hand), you will likely enjoy showing off your plants to your friends, your family will be impressed. Perhaps you will want to learn how to do some preserving. Perhaps you'll try out some new recipes.
Most importantly, you/we will be rediscovering a fundamental skill - how to feed ourselves. We will learn how to tell when the ground is ready, what bugs are good bugs (and which should be drowned in beer), what 'last frost date' really means. We will reconnect with our food and where it really comes from.
Imagine that in a few months from now, you will go to your balcony/deck / backyard and pick a tomato any time you want.
