How to Store Seeds for Maximum Shelf Life

Storing your seeds the right way can extend their viability for years—sometimes even decades. Whether you're saving seeds from your garden or storing heirloom packs for future planting, these best practices will keep your collection fresh, organized, and ready to grow when you are.

Why Seed Storage Matters

Seeds are living things. Inside each shell is a tiny plant embryo waiting for the right conditions to sprout. Poor storage (like heat, light, or moisture) can reduce germination rates or kill the seed entirely.

Good storage = reliable planting and better harvests.

The Big Three: Dark, Cool, and Dry

The three enemies of seed longevity are:

• Light – breaks down cellular integrity

• Heat – speeds up aging and reduces viability

• Moisture – causes mold and rot

Keep your seeds in a dark, dry, and cool place for best results.

Best Containers for Seed Storage

• Original packaging (if sealed and dry)

• Paper envelopes inside airtight containers

• Glass jars with desiccant packets

• Plastic totes with tight lids (add silica packs)

• Mylar-lined Kraft bags (like ours!)

Avoid storing in ziplock bags unless they’re inside a second airtight container with moisture control.

Best Locations

• Basement or cellar (if dry)

• Closet on an inside wall

• Fridge (for long-term storage)

• Freezer (only if seeds are ultra-dry!)

Avoid garages or attics—they’re too hot and humid.

How Long Do Seeds Last?

Some seeds last just a year or two. Others can remain viable for 5–10+ years with proper storage. Here's a quick reference:

• 1–2 years: onions, leeks, parsnips, spinach

• 3–5 years: beans, corn, peas, carrots, basil

• 5+ years: tomatoes, cucumbers, melons, lettuce

Always test germination if you're unsure—plant 10 seeds and see how many sprout.

Tips for Long-Term Seed Savers

• Label everything with variety and year

• Rotate your stock: plant the oldest seeds first

• Use desiccant packs to absorb excess moisture

• Keep seeds in the dark—light causes degradation
