Tumbledown Farm .9 Acres (give or take an acre or two)

Allison Arieff's NYTimes blog entry on edible landscaping today has set off a great conversation (66 responses by 3:15pm!) about the potential of lawns for growing food. You already know that Tumbledown Farm is an example of this "trend" (and has been for nearly a decade). This year alone, we added hazelnuts to the apples, currants, blackberries, raspberries, and veggies galore to our suburban yard of "less than an acre." To the question whether it is "realistic" to grow vegetables in an urban landscape, my response would be "it depends on the urban landscape," but it seems to me that any place where a lawn will grow would be a good candidate for vegetable gardening (even if only at first with lettuce and other "greens").
Another constraint that seems to keep people from trying to grow their own food (other than the aesthetic) is the time and lack of expertise or experience. I am especially intrigued by the story of Trevor Paque's distributed urban farm and CSA (My Farm, cited by Arieff) and I wonder whether it would port successfully to Indianapolis. It would require a different sort of gardening than in SF, but check out his site and tell us what you think. Gardening for a living! There's a concept for some enterprising child of the Midwest. It shouldn't be left only on the left coast.
