How to Freeze Flower Seeds

At the end of the garden growing season, the plants in your garden may have many seeds that can be harvested and kept for planting the next season.  Freezing seeds will keep them healthy and ready for planting next year.  Once thawed, the seeds will grow as normal and you will have full garden once again.

Things you will need:

• Seeds


• Plastic container


• Glass container


• Paper towels


• Strainer


• Cookie sheet or other flat surface


• Freezer bags

1. Look at the seeds and choose only the healthy-looking ones.  You may also choose to purchase seeds from the store and then freeze them.  If you have leftover seeds from a packet you used this year, you can freeze them and save them for next year.


2. Harvest the seeds from the pods and collect them in a plastic or glass container. 


3. Put the seeds in a strainer or coriander.  Run them under cold water and wash off any residue.  Vegetable seeds can also be frozen.  It is recommended to place the seeds in a glass container and let them ferment for one week.  This will kill any viruses or germs.  Wash as normal after fermenting.


4. Shake the strainer to get the residue off.  Use your hands, if needed, to get any dirt or other particles off the seeds.


5. Place the seeds on a paper towel to dry.  Lay them out in a single layer and let dry for about one hour. 


6. Put the seeds in a single layer on a cookie sheet or other flat surface.  Make sure the seeds have room around them so they dry properly and do not grow mold.


7. Set the tray or cookie sheet outside in the sun to dry.  Leave the seeds outside for about one week to make sure they dry completely.  Because most seeds have liquid inside, if they are put into the freezer without drying first, they may explode when the water freezes and expands.


8. Spread the seeds out on a paper towel and put in a freezer safe container.  Use a freezer bag or a tightly sealed plastic container.


9. Freeze the seeds for up to one year.  Do not take out of the freezer until you are ready to use the seeds.  When it is time for planting, thaw the seeds for 24 hours before using.
