10 Ways to Save Seeds Before Summer Ends • Schisandra & Bergamot

As the summer garden begins to wind down, it’s the perfect time to think ahead. Seed saving not only helps you grow next year’s garden for free—it also preserves your favorite flavors, flowers, and heirloom varieties.

With just a little effort now, you can set yourself up for seasons to come. From tomatoes to sunflowers, here are 10 easy ways to save seeds before the summer ends.

Let Plants Fully Mature

Don’t rush! Allow seed-producing parts of the plant—like pods, fruits, or flower heads—to dry on the vine. Mature seeds are more viable and store better long-term.

Harvest from the Best Plants

Choose healthy, productive plants with the traits you want to see again. That way, you're passing down strong genetics into next year’s garden.

Dry Seeds Properly

After collecting, spread seeds on paper towels or screens in a warm, dry place out of direct sunlight. Fully dry seeds won’t mold in storage.

Label Everything Immediately

Trust us: all seeds start to look alike once they’re out of the pod. Label each batch with the plant name and date to avoid confusion later.

Use Envelopes or Glass Jars for Storage

Paper envelopes are great for airflow, while small glass jars can help protect against moisture. Just be sure seeds are fully dry before sealing.

Ferment Tomato Seeds for Better Germination

Place tomato seeds in water for a few days to remove their gelatinous coating. This fermentation process boosts germination success.

Save Flower Heads for Self-Sowing Blooms

Let annuals like zinnias, cosmos, or marigolds go to seed. Snip off the dried flower heads and store them whole—or scatter them directly in fall.

Use mesh bags or old pantyhose to catch seeds that might otherwise scatter too soon. This trick is especially handy with lettuce or dill.

Clean Seeds to Remove Chaff

Winnow or sift out extra plant material so your seeds stay clean and mold-free in storage. This also makes them easier to handle later.

Store Seeds in a Cool, Dry Place

A dark, dry cupboard or sealed container in the fridge will help seeds last longer. Avoid humidity and fluctuating temps to keep them viable.

Seed saving is one of the simplest, most satisfying ways to connect with your garden year after year. It’s thrifty, sustainable, and incredibly rewarding. Start now, and you’ll thank yourself when next spring rolls around.
