How long will tomato seeds keep?
Comments (4)There are recorded instances of 50 year old seed being germinated under ideal conditions, germination of 15-20 year old seed when frozen is fairly common, and whenever this question comes up on the Tomato forum and the Seed Saving forum here there are many reports of 5 year old seed or more being used. Of course proper storage - cool and dry - will determine longevity. Personally I frequently use 5-8 year old tomato and other common vegetable seeds.

Comments (15)Many seed companies just recycle last years seeds. The garden centers ship them back to the distibutor and they test to see of the seeds are still germinating. If they get good germination rates, ( not sure what the percentage is), they just repackage them for the next year with a new date on the package... so your seeds may actually be older than the package states. It kinda defeats any knowledge of how long seeds actually last, but also encourages me to keep seeds a long time. If the seed companies are recyling seeds each year, I can too. On a side note, I am growing peppers from seeds I bought last year and from seeds I saved from a pepper last year, and the ones from the pepper are growing WAY better. Maybe because they are fresher, or it could be the variety. Just food for thought....See MoreHow long can I keep the seeds?
Comments (9)I'm thinking about buying tomato and bean seeds throught internet. Usually it comes in a package of 20-25. I would like to use only 5 for this year. Would the rest last forever if I store them in a dry cupboard? **** You have several choices as to how to store the tomato seeds. You can keep them in a cool dry spot with the packs tightly closed. You can put them in a jar, tightly sealed, and put it in the fridge. You can dry them down to a moisture level of about 6-8% and freeze them. I wouldn't say tomato seeds last forever, they can't, but the documented germination of seeds 50 years old was done when the Cheyenne precurser to the USDA was moved from there to Ames IA. My own record is waking up 22 yo seed but often that means using special little tricks. Another important factor is knowing the age of the seeds when you buy them, and even though a pack may say packed for 2008 that doesn't tell you how old the seeds are, it just tells you when they were packed. I keep my seeds in vials and some in open envelopes and they're kept at ambient temperature and I expect a germination of at least 50% and often much more from my own saved seeds. I know of only one tomato source where no tomato seeds sold are older than two years and that's Sandhill Preservation. Some of the smaller companies may also be offering some varieties that are fresh, but new stock plantings are rotated so any given place may be selling seeds for different varieties that are of varying ages. Since you're in Toronto you don't have to deal with blistering heat and humidity so if it were me I think I'd store your seed dry and cool and let it go at that. I'm not addressing the bean seed issue in detail b/c beans aren't tomatoes, LOL, but bean seed does do best dry and cool and has a longer shelf life than tomato seed does. Hope that helps.
