New York times recently wrote a story:
"Urban farming is the latest Bay Area trend everywhere except downtown Sonoma, where city crops have been harvested for more than a century. Only about a block from Sonoma Plaza and across from Vella Cheese on Second Street East is The Patch, a 140-year-old, six-acre farm yielding Mission figs from century-old trees and Goldie heirloom tomatoes, as seen on farm-to-table menus at Barndiva in Healdsburg.
The Patch belongs to the Castellano family, which raises Clydesdale horses up the street. Since 2004, the space has been cultivated by Lazaro Calderon and his brothers. Mr. Calderon gave up truck driving in Arizona to use pesticide-free, labor-intensive methods to farm The Patch, planting cover crops and nitrogen-rich beans in the off-season to replenish the soil. "
