I remember wife and I putting in a small garden of edibles some years back and being very pleased with what I got, but the thing is by the time the plants began bearing edible peppers, tomatoes, etc., everybody else's garden was in harvest mode as well, and you could get all that stuff for somewhere between free and ultra-cheap lest it just go to waste. Why do all that work when you can have what you want anyway without doing anything? Of course, if everybody thought that way, we wouldn't have any of those things, but I don't think there's much risk of that.
