Storing Seeds Collected in November

November’s garden tidy-up yields a treasure trove of seeds—from the last sunflowers and marigolds to annual veg, self-sown herbs, and even favorite perennials. Storing seed properly now means you’ll have a rich supply for sowing, swaps, or gifting come spring. Here’s your step-by-step guide to keeping your November seed harvest viable and ready for next year’s growing season.

1. Clean and Dry Seeds Thoroughly

• Sort from chaff: Gently rub, shake, or sieve to separate seeds from stalks, pods, petals, or fluff.
• Dry well: Spread in a single layer on newspaper, kitchen towel, or a plate in a cool, dry, airy place—away from direct heat and sunlight.
• Drying time: Most seeds need at least 7–10 days; test by pinching—fully dry seeds are hard and snap, not bend.

2. Choose the Right Storage Method

• Paper envelopes or packets: The best classic option—let seeds breathe and prevent condensation.
• Glass jars: Use only if seeds are bone-dry, and add a sachet of silica gel or a teaspoon of dried rice for moisture control.
• Small boxes, seed tins, or pill bottles all work if kept in a dry, cool place.

3. Label Clearly and Completely

• Name of plant (common & Latin if desired)
• Variety or color, if known
• Date and place of collection
• Any special germination notes (e.g. “needs stratification” or “soak before sowing”)

4. Store Cool, Dry, and Dark

• Best temperature is just above freezing—think garage, shed, cellar, or sealed tin in the fridge (not freezer).
• Avoid kitchens, greenhouses, or damp sheds—fluctuating heat and humidity spoil seeds fast.

5. Check Periodically

• Inspect stored seeds over winter: toss any that show mold, musty smell, or insect damage.
• Make a sowing calendar or keep a seed log for when to plant each type next year.

Pro Tips

• Most home-saved flower or veg seeds keep for 1–3 years when stored well.
• Seed swaps in February/March are a great way to diversify your collection.
• For special or rare varieties, divide a batch between two envelopes/locations as insurance.

Careful seed storage in November is a small job with a big reward—turning a year’s end clean-up into next spring’s new beginnings.
