It’s especially vital if you’ve saved your own seeds to make sure they’re thoroughly dry before storing them. Simply lay them out on paper and let them air dry for approximately a week. (Keep various varieties of seeds on separate sheets of paper, each clearly labeled.)
When you apply force to the seeds, they should crack or shatter. They aren’t dry enough for storing if they just bend without cracking or if they are crushed.
Seeds that haven’t completely dried are vulnerable to harm. They may mold or grow if kept at room temperature. They may decay in the fridge and suffer frost damage in the freezer.
A desiccant can be added to stored seeds to keep them dry. Tossing a little silica-gel-type package of desiccant into the storage container is simple.
Wrap a few teaspoons of rice or powdered milk in several layers of facial/toilet paper or cheesecloth.
How do you preserve seeds for decades?
Place the envelope in a plastic zip bag and close it tightly, sucking out as much air as possible. You may also vacuum seal them with a Food-Saver.
Place the seed bag at the back of the freezer, where it will not be disturbed. If you store your seeds in a cool environment, they can survive for up to ten years.

How To Store Them Properly For The Long Term
What if you have a huge seed collection or want to switch out kinds every other year or so? Perhaps you’re being proactive and conserving seed for survival?
The best technique to keep seeds for a long time is to establish ideal circumstances for your seeds to thrive in.
The key phrase is “cold and dry.”
There should be no wetness surrounding your seedlings ideally. Temperatures should be at 40 degrees Fahrenheit or lower, but not below freezing, as this will harm certain plant embryos. It should be dark or gloomy, and devoid of pests and critters.

Few people would toss away seeds we don’t intend to utilize. Whether there are too many seeds in the packets we buy (and we don’t plant them all), or we store our own seeds, we’ve all probably had a seed stockpile at some point.
That’s an issue since seeds lose viability over time unless securely frozen. Their germination rate declines as they age.
However, with a little care, you may easily extend the life of your seeds. Some gardeners have used this strategy to store seeds for up to 30 years.
