I am in southwest central New Brunswick, Canada, USDA Zone 4b/5a. I bought an acre with a tiny 1896 farmhouse on it in 2005, and put in my first small garden in the summer of 2008 after getting married. In the summer of 2009 we bought another 2 acres (1/3 old field with a couple of old apple trees, the rest a 10 year-old clear cut), and started a massive reno/expansion of the house, and also foolishly started a 20-member organic CSA program that same summer out of a 1/4 acre new garden (that had been a old hayfield)....all while working full time as a civil servant. Biting off that massive amount of work didn't endear the idea of permaculture to my wife to say the least.
I gave up the CSA after the one year. It was a horribly cold, wet summer but despite the low yields all but a few of my customers would have returned if I'd kept with it, so that was encouraging. Since then I've devoted the 1/4 acre to growing food for my wife and I, selling/giving away a bit of our extra. I would have chickens and pigs if my wife would allow it - I'm still working on her! We don't buy any herbs or vegetables at all (except avocados) between early July and late December, and then only tomatoes, peppers, and greens for the remainder of the year. We can/freeze a ton of tomato paste, and this year I made about 30 bottles of dill pickles and 25 of salsa, all lacto-fermented (the easiest and best way, IMO). I also trade veggies for wild meat and fish with my hunter/fisher friends, although not nearly enough to fulfill our needs.
I planted 10 Haskap bushes (Google them!) this year, and have several apple/pear/plum/cherry trees, although most aren't producing yet.
I grew some Oaxacan Green Dent corn this year too, and am hoping to successfully make masa out of it for tortillas, etc. We eat more Mexican food than anything else, so ideally I'd like to be able to grow all of the corn required for that.
Now I'm looking for any excuse I can find to quit my job and start up the CSA again, full time, supplemented by furniture/cabinet making in the winter. I will probabaly rent the extra land required for that, as there are dozens of acres of fallow fields belonging to my neighbours within a 5-min walk from my front door. Much less effort and $$ required than to convert the clear cut to a garden.
