Mission. The Philadelphia Orchard Project plants orchards in the city of Philadelphia that grow healthy food, green spaces and community food security.
POP works with community-based groups and volunteers to plan and plant orchards filled with useful and edible plants. POP provides the plants, trees, and training. Community organizations own, maintain, and harvest the orchards, expanding community-based food production. Orchards are planted in formerly vacant lots, community gardens, schoolyards, and other spaces, almost exclusively in low-wealth neighborhoods where people lack access to fresh fruit.
