Storing Seeds Long Term in Mylar: How to Keep Your Seeds Safe for Years

For gardeners, farmers, or preppers looking to save seeds for long-term storage, nothing beats the effectiveness of using mylar. While there are other ways to store seeds, mylar bags provide the perfect protection for countless types of seeds, allowing you to keep them viable for years down the line.

Mylar bags are thin plastic pouches made from either polyethylene terephthalate or biaxially oriented polypropylene. Their high barrier properties protect their contents from moisture, oxygen, light, and even pests and rodents. When storing your seeds in mylar, they can remain viable for up to 10-12 years.

A few steps should be taken when storing seeds in mylar to ensure success. First, clean any dirt or debris off of the seed before placing it into the bag. This will help protect against mold and bacteria growth. Second, make sure the bag is airtight by adding a desiccant packet and sealing it closed. Desiccant packets are available at many stores, and they help pull moisture out of the air and keep the bag dry.

The next step in properly storing your seeds is to fill the mylar bag. It’s important not to overfill the bag, as this can put pressure on the seeds, reducing their viability. And make sure to leave some space between the top of the bag and the zipper so that air can circulate. Finally, label the bag with the type of seed and the date it was placed in the bag.

Once all of these steps are completed, the mylar-stored seeds can then be placed in a cool, dark location. Avoid placing the seeds directly on concrete or other heat-conducting surfaces, as this could damage them. A good place to store would be in a basement or closet, away from direct sunlight.

Storing seeds in mylar is one of the most effective ways to ensure they last for several years. With a few simple steps, you can keep your seeds safe and secure for future use. So the next time you’re harvesting your crop, don’t forget to set aside some of the seeds for long-term storage in mylar!
