The Insight Garden Program (IGP) rehabilitates prisoners through the process of organic gardening. The IGP’s classes include classroom course curricula and hands-on experience in a 1,200-square foot organic flower garden in San Quentin’s medium-security prison yard. In the classes, men learn about landscaping and gardening, including (but not limited to): planning, budgeting and design, irrigation, soil amendment, seasonal garden maintenance, and plant ID and propagation.
