Greenhouse Manual: An Introductory Guide for Educators, a project of the U.S. Botanic Garden, NCAT, and City Blooms, has been honored with a 2nd place national award by the American Alliance of Museums in the Education category of their publications awards. The manual is an easy-to-use guide designed to help educators who have access to greenhouses with planting gardens, growing for farm to school programs, or integrating plant science into an existing curriculum. The manual opens with a basic explanation of greenhouses and continues with how to integrate their use into classroom and out-of-classroom learning. It contains lesson plans and information on greenhouse operation, growing plants, starting seeds, plant nutrition, disease and pest management, greenhouse budgeting, and succession planting. The manual is available free online.
