long term seed storage?

Recommended Posts

Mod's I'm not sure if this should be here or in another forum. Please move if needed. Does anyone have any ideas about storing seeds for long term? Any success/failures? I have read a lot of different articles and some posts here on MrsS and I'm more confused :0327: than ever. Some say to store in a paper bag because the seeds need air, some say store in plastic bags in refrig and some say not to vacuum seal or use O2 absorbers but I have found suppliers of heirloom seeds that sell a Victory Garder in a # 10 can vacuum sealed! Currently, my seeds are in plastic bags in the refrig. I'm not sure if that's the right way or not. Help :(

newcreation, your biggest enemy would be moisture. Other than that, opinions do vary. Keep in mind that with age, germination rates are going to go down.

 

Perhaps these will help you:

Thanks Sere. Read thru all the websites and I think I'm going to add the powdered milk to absorb moisture like they said and leave in the plastic bags in refrig. Bookmarked these sites for future reference.

ANew:

 

The World Seed Bank freezes their seeds. For seeds that you have purchased which have already been dried, put envelopes in an airtight jar & into the freezer. There is air in the jar but the jar keeps moisture out.

 

Seeds that you process yourself from plants need to be dried first down to about 4-5 % mositure (i think), then put in jars & into freezer for longest shelf life.

 

I plan to use the same thing they dry flowers with to dry my seeds that we produce this year.

 

Hope this helps.

I think I might leave some in the plastic bags like I currently have and put some in the freezer in a can/freeze jar. No need having all my "eggs" in one basket :) . Thanks

The Uk has a huge seed bank, at Kew Gardens in London. As far as I can remember they store them in controlled temperatures. They are trying to gather together every seed in the Uk and keep it. Anyone with a rare seed is advised to send them some to store in case of chrises.

 

 

Heres the website for it, they might be able to advise you further:

You know I was wondering the same thing. I've ordered hybrid nonGMO seeds this year and I know I'll never use them all and would hopefully be able to save them for next year. I think I to will try both methods...plastic bag in fridge....some in freezer.

Seeds of all food plants can be safely stored many years (in most cases for up to ten times longer than normal germination rates), if they are frozen in airtight containers, and if the seeds are dried to about 8% moisture. If they are not dry enough, the excess moisture inside the seeds will expand when frozen and derange their internal cell walls. As a result, germination and seed vigor will be poor.

 

How dry is enough? Usually, if the seed breaks or shatters instead of bending when folded or whacked with a hammer, it is good to go.

 

The next best place to store seeds would be the refrigerator. Failing that, a cool, dry and dark place would be third best.

 

Tip: When you take your seeds out of the freezer or refrigerator, allow the container to completely reach room temperature before opening (overnight is best). If you don't, you may have problems associated with condensed moisture inside the container.

 

Because fluctuations in temperature will also shorten the shelf life of seeds, I like to my package seeds in many smaller containers instead of a few large ones. That way I don't thaw out a big wad of seeds when I just need to remove a few...
