Stern and Brock strike a pose with their gardening tools. Charlie Nardozzi, senior horticulturist with the National Gardening Assn., said that after the second World War, gardening became mostly a hobby in the '50s and '60s. But then came the "back to the land" movement of the 1970s, when growing food again had serious purpose. It petered out in the '80s and '90s but has surged again today, buoyed by philosophical issues as well as economic ones, Nardozzi said.
