Life Span of a Seed

Evening all.
I would like to know how long a weed seed will remain viable for. If any one knows.
Shelf life I guess you would call it please.
Thank you


They can last up to 10 years or longer if properly stored.
Refrigerated , dark , humidity controlled.
Generally 2-3 years otherwise.


Many years if kept in a cool, dry, dark place. I put mine in containers in the veg drawer at the bottom of the fridge where is is cool, dark, and humidity is very low.

I’ve kept my seeds in the fridge and they re just as viable as when I bought them a year ago ive heard of 5-10 year old seeds stored in a dash board germing fine too but the shock of cold to room temp helps germ the seeds imo


I have seeds from about 11 or more years ago they r shit bag beans but i dropped e to get started year and a half ago and all 3 popped. Started right at the atart of covid lockdown and had the seeds id say atleast 11 to 13 years maybe even longer in a drawee in a pill bottle inside a plastic bag. Just an accidenf looking in the drawer and wife seen them when i found them and when i went to work she dropped 3 for me to get started. Best move she did beside marrying me lol. Love this sport
