Edible Walls Growing in L.A.

"Some Cal Poly students and staff have their minds set on growing 4,000 fruit and vegetable plants in the concrete jungle of Los Angeles — on the walls of four downtown buildings.

They helped load trucks last week with panels of plants that they made and plan to mount.

The group hopes the so-called “edible walls” will benefit many homeless and low-income residents in housing complexes in the city’s Skid Row area and at Miguel Contreras Learning Complex, a downtown high school.

The method of farming on walls addresses the lack of space in the urban area; the sideways-resting planters span 30 feet across."
