To effectively store mixed seeds and prolong their viability, focus on reducing humidity, maintaining cool temperatures, and using appropriate containers.
Key Steps for Storing Mixed Seeds
-
Reduce Humidity: This is the most critical factor. High humidity accelerates seed deterioration.
- Drying Seeds: Ensure seeds are thoroughly dry before storing. You can spread them out on a tray in a cool, dry place for a few days.
- Desiccants: Consider adding a desiccant, such as silica gel packets (available at craft stores) or even powdered milk wrapped in a coffee filter, to your storage container to absorb any residual moisture. Be sure to replace desiccants as needed if they become saturated.
-
Maintain Cool Temperatures: Store seeds in a cool place to slow down respiration.
- Ideal Location: A refrigerator or cool, dry basement is often a good choice. Avoid locations with significant temperature fluctuations.
- Temperature Range: Aim for temperatures below 40°F (4°C) for long-term storage.
-
Use Appropriate Containers: Choose airtight containers to protect seeds from moisture and pests.
- Options: Sealed glass jars, plastic bags (resealable, like Ziploc), and wax or paper envelopes can all be used. For long-term storage in the refrigerator or freezer, glass jars are generally preferred.
- Labeling: Clearly label each container with the type of seeds (even if mixed, specify the mix), date of storage, and any other relevant information.
Best Practices for Mixed Seeds
- Store Separately When Possible: If you have a large quantity of mixed seeds, consider separating them into smaller batches for easier use and to avoid repeatedly exposing all seeds to air when you only need a few.
- Check Seed Viability: Before planting, especially after long storage periods, conduct a germination test by placing a few seeds on a damp paper towel, enclosing it in a plastic bag, and waiting to see if they sprout. This helps determine if the seeds are still viable.
By following these guidelines, you can significantly extend the shelf life of your mixed seeds and ensure a successful planting season.
