How to Tell the Germination Rate in Old Seeds

If you just can’t bear to throw out those old seeds, here’s a test to tell how viable your older seeds are. Take 10 seeds and soak for about 1 hour, then put them between damp paper towels and in a plastic ziplock baggie. Put in a warm spot (on top of your refrigerator or on a grow heating mat). Keep checking them daily and when you get them to germinate, count up how many actually did germinate. If you got 3, then you have a 30% germination rate, 5 would be a 50% germination rate and so forth. If you only get 1-2, throw them out, their not worth the trouble. So if you have a 100 seeds, then you can be pretty assured that around 30 would germinate (30% rate).
