While your plants may be seasonal, the seeds can last much longer. Some seeds, such as leeks and parsley, won't last more than a year, but the 8 seeds listed below have the viability and vigor to last up to 5 years. However, their actual survival depends on the storage process you follow. As a result, it's important to learn what has worked for others:

Best Method of Seed Storage

Seeds are best stored in cool, dry locations. A general guideline is to keep the combined temperature and humidity level under 100. As an example, the ideal temperature for seed storage is about 40-45 degrees Fahrenheit, which would allow for a maximum humidity level of about 50 percent. To keep your seeds dry, store them in an airtight container. Glass jars with rubber seals on their lids, like baby food or home canning jars, work best. If you’re concerned about moisture within the jar, you can add in a desiccant such as rice.

Keeping the seeds in the fridge or freezer is an excellent way to maintain perfect storage conditions. Keep in mind that frost-free fridges and freezers work by drawing out moisture, and can seriously dry out seeds.

Freezing seeds properly can exponentially prolong their longevity. After all, seed banks like the Svalbard Global Seed Vault count on freezing to keep their seeds viable for centuries. The home gardener shouldn’t expect her own seeds to last quite as long in a home freezer, given the strict scientific protocols and optimal conditions of the Global Seed Vault. Still, frozen seeds should remain viable longer than seeds stored at room temperature.

8 Seeds That Easily Store for 5 Years

While storage methods have a big impact on seed longevity, the type of cultivar also makes a difference:

• Broccoli
• Cabbage
• Cauliflower
• Cucumber
• Muskmelons
• Spinach
• Radishes
• Lettuce

Have you been able to long-term store any of these seeds? Are there any other tips for extending the longevity of our seeds?
