How To Store Seeds For Decades

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 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.”

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.

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.
