This is just my opinion (take it for what it's worth), but I wouldnt refrigerate potatoes under any condition, sprouting or not. If you have access to peat moss, I would store them in some of that, moistened, of course

Hi Glacier - most likely not as that type of storage isn't noted for long term preservation. However you can do a germination test on it to know for sure. Scatter 10 seeds on a well-damp coffee filter, fold it over and place it in a sealed ziplock bag and place it near a sunny window. Check after 3 days and daily thereafter for any germination. If none germinate within 20 days you might as well pitch it. But if some do, the number that germinate will give you a good indication of the % of germination you can expect from the rest. Good luck.

I've started canna seeds 3-5 years old and had almost 100% germination rate. I let them sit out for about a week, put them into a baggie or envelope, and just store them with the rest of my seeds in a box in a closet. Jenna

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. Carolyn
