>However we still don't feed everyone from small household gardens. If I had to survive solely on crops I've grown myself I would perish. Putting aside economies of scale, I am lucky if I manage to grow a couple of decent size tomatoes or a decent carrot (singular). I'd be lucky to grow enough food for a day or week, let alone a season. Partly this is because I live in an area with bad soil (too close to beach, sandy), and partly because I just seem to be a well meaning plant killer. Would be nice though. I have had some success with growing seedlings in a mini greenhouse, but as soon as they're out in the yard in bigger pots they start to fail.
