Seed Saving

Square Version of Seed Saving Logo The seed saving initiatives within the University of Hawaii at Manoa College of Tropical Agriculture and Human Resources (CTAHR) work to provide a framework for coordinated outreach and training to increase stakeholder knowledge and capacity around seeds.

Building the knowledge base for seed production in Hawai‘i will lay the foundation for increasing the selection, development, and popularization of better adapted local crop varieties in the future.

Basic Seed Equipment for Public Benefit Projects
Extension offices on Maui, Hawaiʻi, Oʻahu, and Kauaʻi have supplies such as screens and mesh strainers for groups interested in producing seed for public use (e.g. seed libraries, seed exchanges, school gardens). Interested parties can contact their local extension office to inquire about using this equipment.
