Au contraire. You need to read up on French intensive gardening. And I don't consider myself an amateur by a long shot. Aside from that, by ongoing I mean something past when the severe food shortages hit and stored food is dwindling.

I certainly didn't infer that we're only talking to suburban people with tiny yards. Actually, my point was that if you are just getting around to thinking about a garden to feed you this winter, it's probably too late unless you're in a very warm, frost free zone.
