National Seed Swap Day

National Seed Swap Day is observed on the last Saturday of January. In 2026, it falls on January 31. This observance serves as a community-driven kickoff to the gardening season, encouraging the exchange of seeds, stories, and growing tips among neighbors. It focuses on the practical benefits of biodiversity and the preservation of heirloom plant varieties that might not be available in commercial stores. By sharing seeds before the spring planting season begins, participants ensure that local gardens remain diverse and that unique regional plant strains are protected for future generations.

History of National Seed Swap Day

The official holiday was established in 2006 by Kathy Jentz, the editor and publisher of Washington Gardener Magazine. The first official event took place on January 26, 2006, in Washington, D.C., and was designed to revive the ancient tradition of seed bartering in a modern, urban setting. Jentz recognized that while industrial agriculture had centralized seed production, the cultural heritage of passing down “grandmother’s tomatoes” or specific regional flowers was at risk of disappearing. The success of this inaugural exchange inspired gardening clubs across the United States to adopt the last Saturday of January as a day for local swaps.

While the formal holiday is relatively recent, the act of swapping seeds is as old as agriculture itself. For millennia, travelers and farmers carried seeds in their pockets as they moved across continents, using them as a form of currency and a way to establish new roots. In the United States, early colonists and indigenous peoples relied on these exchanges for survival and the development of crops like corn, beans, and squash. National Seed Swap Day honors this historical necessity by transforming it into a social and educational celebration that supports local food security and environmental health.

Why is National Seed Swap Day important?

This day is essential for maintaining biodiversity within local ecosystems. When gardeners exchange seeds that have been successfully grown in their specific climate and soil, they are effectively distributing “tried and true” genetics that are more resilient than generic, mass-produced varieties. This practice helps protect the global seed bank from the risks of monoculture and genetic uniformity. Furthermore, seed swapping is an economical way for individuals to expand their gardens without the high cost of buying individual packets for every plant variety they wish to try.

The social aspect of the day is equally significant as it connects generations of gardeners. Experienced “green thumbs” often use the event to mentor beginners, sharing specific knowledge about germination, pest control, and harvest timing. It also serves as a cultural bridge, as many families bring seeds that have been in their lineage for decades, allowing them to share a piece of their history with their community. By encouraging people to grow their own food and flowers, the holiday promotes self-sufficiency and a deeper appreciation for the natural lifecycle of plants.

• Seed swapping preserves rare heirloom varieties that are often tastier than commercial produce.
• Locally adapted seeds are typically more resistant to regional pests and weather patterns.
• Exchanging seeds reduces plastic waste associated with commercial packaging and shipping.
• The event provides free access to fresh food sources for people in urban or low-income areas.
• Participating in a swap fosters a sense of community and shared environmental responsibility.

How to Celebrate National Seed Swap Day

To participate, begin by sorting through your existing seed collection to identify surplus packets or seeds you harvested from your own garden. Place these seeds in small envelopes or jars and label them clearly with the plant name, variety, and the year they were collected. If you are a beginner with no seeds to trade, most community swaps welcome newcomers and are happy to provide “starter” seeds to help you get started. The goal is to leave with a variety of new plants to try, from vibrant annual flowers to hearty winter vegetables.

You can also celebrate by attending a local event at a library, community center, or botanical garden. Many of these gatherings feature guest speakers who provide demonstrations on how to properly clean and store seeds to maintain their viability. If there is no event in your area, consider starting a small exchange with your immediate neighbors or through a local social media group. Even a simple “leave a seed, take a seed” box on your porch can serve as a meaningful way to observe the spirit of the day and encourage local gardening.

• Label your seed envelopes with specific planting instructions and sun requirements.
• Bring a notebook to jot down tips from more experienced gardeners at the swap.
• Offer to help organize or set up tables at a local community seed exchange.
• Share photos of your seed haul on social media to inspire other gardeners.
• Research the history of any heirloom seeds you receive to appreciate their origin.
