OpenFarm is a collaborative, open-access platform for farming and gardening knowledge, structured around “Growing Guides” — detailed, user-created documents that describe how to grow specific plants under different conditions. Each guide includes actionable information such as planting schedules, spacing, soil preferences, light requirements, and care routines. Inspired by a mix of Wikipedia and recipe websites, OpenFarm offers an API-accessible, crowdsourced dataset designed to support humans and machines alike in learning how to grow food more effectively.
