Bought more seeds than you'll plant this season? Knowing how to store seeds properly can keep most varieties viable for years. Bad storage can kill germination rates within months. Here's how to protect your investment.

The Two Enemies of Seed Viability: Moisture and Heat
Seeds are living tissue in a dormant state. Warmth and humidity signal them to either germinate prematurely or degrade. The goal of storage is simple: keep them cool, dry, and dark.
Ideal Storage Conditions
Temperature: a cool, stable spot — ideally below 20°C (68°F). A refrigerator (not freezer) works well for long-term storage of most species.
Humidity: low. Adding a silica gel packet or a few grains of dry rice to your storage container absorbs excess moisture.
Light: store in an opaque container or envelope — direct light degrades seed quality over time.
Containers: airtight glass jars, sealed envelopes, or resealable bags all work, as long as they're moisture-proof.
Label Everything
Write the variety name and purchase or packing date on every container. Even well-stored seed loses some viability over time, and knowing the age helps you decide whether to run a quick germination test before committing a full season to it.

Quick Pre-Planting Viability Check
Place 10 seeds on a damp paper towel, fold it, and keep it in a warm spot for the variety's typical germination window. Count how many sprout — that percentage gives you a rough estimate of your current germination rate before you commit an entire bed.
Frequently Asked Questions
How long do seeds stay viable in storage?
Many vegetable and herb seeds remain viable for 2-4 years under good storage conditions; some flower seeds last even longer, while delicate varieties are best used within a year.
Should I store seeds in the fridge or freezer?
A refrigerator is generally recommended for most seeds; freezing is only advisable for certain species and requires extra moisture control to avoid damage.
How can I test if old seeds are still good?
Run a damp paper towel germination test with a sample of 10 seeds to estimate your current germination rate before planting a full bed.
