* Vegetable and flower seeds may be kept for one year without appreciable decrease in germination.
* Storage may be extended to 10 or more years under proper conditions.
* Seed moisture and storage temperature are the most important factors in determining how long seed can be stored.
* The drier the seeds are, the longer they will store.
Storing Vegetable and Flower Seeds (Colorado State University)
I would be really careful about using heat to dry them though. Just a bit too hot and poof.....
To give you an idea how long they will store, just consider that they have found viable wheat and flax seeds in the pyramids in Egypt. I store mine in a mason jar vacuum sealed (using vacuum pump not heat processed) and store them in a second fridge.
Thank you both.
Some good advice there on using the canning jars.
I hate to admit, but I’ve never canned anything.
Maybe we could have one day a week where we learn something new and do it - all of us. :)
