Saving seeds is one of the simplest and most powerful ways to participate in a gardening community.
It’s also one of those things that feels easy… until you realize there’s a little more to it.
Not all seeds are created equal when it comes to saving and sharing. Some stay true year after year. Others like to mingle a little too freely.
If you’re planning to bring seeds to the Seed Swap, here’s a quick guide to help you know what to save, what to watch for, and how to care for your seeds so they stay viable.
🌼 The Easiest Seeds to Save (Great for Beginners)
Some plants are naturally good at keeping their genetics consistent. These are the best seeds to start with if you’re new to seed saving.
Look for:
- Tomatoes (especially heirloom varieties)
- Beans
- Peas
- Lettuce
- Peppers (with a little spacing awareness)
These plants are mostly self-pollinating, which means they’re less likely to cross with nearby varieties.
If you saved seeds from these and labeled them well, they’re wonderful to bring to a seed swap.
⚠️ Seeds That Cross-Pollinate Easily
Some plants are a little more… social.
They can cross with other varieties of the same species, especially if they’re growing nearby. When that happens, the seeds may not grow into what you expect next season.
Common cross-pollinators include:
- Squash (zucchini, pumpkins, etc.)
- Corn
- Cucumbers
- Brassicas (like broccoli, kale, cabbage)
That doesn’t mean you can’t save them — it just means it takes more planning, like spacing varieties far apart or hand-pollinating.
For the Seed Swap, it’s helpful to label these clearly if you’re unsure:
👉 “May have cross-pollinated”
👉 “Open pollinated, variety uncertain”
Honesty helps everyone grow better plants.
🌾 What Makes a “Good” Seed for Sharing?
When you bring seeds to a swap, you’re not just sharing a plant — you’re sharing an experience.
Good seeds for sharing are:
✔ Fully mature (left on the plant long enough)
✔ Properly dried
✔ Clean (free of pulp or debris)
✔ Labeled clearly
If you can, include:
- Plant name
- Variety (if known)
- Year harvested
- Any notes (flavor, growth habit, etc.)
Even a few handwritten details can make someone’s garden more successful.
🌿 How to Care for Your Seeds
Seeds are living things. They may look still, but they’re quietly waiting for the right moment.
How you store them matters.
Keep seeds:
- Cool
- Dry
- Dark
A few simple tips:
• Store seeds in paper envelopes or glass jars
• Keep them in a drawer, cupboard, or cool room
• Avoid moisture at all costs
• Label everything (you will forget later)
What to avoid:
🚫 Leaving seeds in a hot car
🚫 Storing in damp areas
🚫 Sealing seeds before they’re fully dry
Heat and moisture are the fastest ways to reduce seed viability.
⏳ How Long Do Seeds Last?
Not all seeds have the same shelf life.
General guidelines:
- Beans, peas: 2–4 years
- Tomatoes, peppers: 3–5 years
- Lettuce: 1–2 years
- Onions: often just 1 year
If you’re unsure, you can always do a simple germination test at home.
But even older seeds can still be worth sharing — just label the year so others know what to expect.
🌼 Seed Swapping Is About More Than Perfection
Not every seed has to be perfect to be valuable.
Seed swaps are about learning, experimenting, and sharing what works — and sometimes what didn’t.
If you’re new to saving seeds, bring what you have and be open about what you know.
That’s how knowledge grows in a community.
🌱 A Place to Learn, Share, and Grow
At the 20th Annual Community Seed Swap hosted by Spiral Living Center, you’ll find seeds, scions, and stories being shared across generations.
🌿 Bring what you can. Learn what you don’t know yet.
That’s the spirit of a seed swap.
And it’s how a garden — and a community — continues to grow.
