At my last house I had about a 30ft by 50ft garden plot. Not enough to totally subsist, not even close. To live off of, year round, you are into acres. You are canning, preserving, pickling and drying. Rotating crops, and using the entire growing season, even starting seedlings in cold frames, which I did do for a few years.
Something to consider, from a survival situation, should someone really want to be food independant. A lot of the plants we grow are hybrids. Take tomatoes for example. It's getting more difficult to find varieties that you can use the seeds to grow next years crop. Thye are hybridized to the point their seeds won't grow next years crop. part of me thinks this is a nice way for the governments of the world control the populations food supply. The other part of me knows it's because we want fatter tomatoes for our burgers, so we have scientifically engineered them in one direction, while sacrificing some other traits.
So, for anyone wanting to get gardening, and be able to subsist without outside help, be certain to research and use some good old fashioned varieties that can and will reseed themselves. Use the seeds from the biggest largest plumpest best specimens you have to keep your quality high year over year.
I'm scoping my current property for a good place for another garden. We have a huge deer problem, so, I'm looking at some serious fencing issues. And before anyone says just shoot them....last year my neighbors took 33 deer, this year there are still even more. Legally, we don't think we can thin them down enough to make an impact....but, on the other hand, for a survival situation when the government can't help and the local grocery store is belly up, we know where to harvest some serious amounts of venison.
The moral of that story, when in a long term survival situation, your garden is going to feed you with plant crops, but it's likely to draw in some "meat" crops, as well. :thumbup:
