National Seed Swap Day is celebrated on the last Saturday in January, specifically on January 31 this year, to honor the tradition of swapping seeds with neighbors in the United States. This day marks the transition from winter to spring, encouraging communities to gather and plan for the upcoming planting season. Participants engage in seed exchanges, fostering a sense of community and shared purpose in gardening. The event promotes biodiversity and reflects a growing interest in home gardening and urban farming, which has surged since the 2000s. National Seed Swap Day serves as a reminder of the importance of nature and self-sustenance, as communities come together to share their gardening experiences and resources.
