Well, I agree that its great to encourage people to grow some of their own vegies. We have been increasing the vegies we grow for several years now. Its trial and error, but its both satisfying and saves some money, although that's not our main purpose. Its great to be able to go out into the garden and harvest something to include with dinner.
We also avoid supermarket vegies and shop in local markets because the food seems to last longer.
I suggest people just focus on a few vegies they eat a lot of or that are easy to grow, and add bought vegies to it.
There was a time when most Aussie houses had backyard vegie gardens. Actually, you don't need a yard, as many vegies can be grown in pots or other ways. For example, we have a hanging bag of strawberries.
Put in a rainwater tank and you're away.
Its also a good way of encouraging children to get their hands dirty and learn something useful for their later lives.
