What is the best temperature for storing seeds?

Seeds should be stored at a temperature between 32°F and 41°F (0°C to 5°C). This helps maintain their viability by slowing down metabolic processes.

How long can seeds be stored in plastic containers?

When stored correctly, seeds can last from one to five years, depending on the type. Some seeds, like beans and peas, can last up to five years, while others, like onions, may only last one year.

Can I store seeds in the freezer?

Yes, storing seeds in the freezer can extend their lifespan. Ensure they are in airtight containers to prevent moisture buildup, which can damage the seeds when thawed.

Are there alternatives to plastic containers for seed storage?

Yes, alternatives include glass jars with airtight lids, metal tins, and vacuum-sealed bags. Each has its own benefits and drawbacks, such as weight and cost.

How do I know if my seeds are still viable?

To test seed viability, place a few seeds on a damp paper towel, fold it, and seal it in a plastic bag. Check after a week to see if any seeds have sprouted. This indicates they are still viable for planting.

Conclusion

Storing seeds in plastic containers is a safe and effective method when done correctly. By choosing the right container and following best practices, you can ensure your seeds remain viable for future use.
