Notes

An Old Seed is one that is less viable, and thus less likely to germinate. They lose lustre and color, and exhibit decreased resistance to fungal infection. The integrity of cell membranes is also compromised, and old seeds leak more substances than fresh seeds. This phenomenon can be attributed to aging. In addition, an Old Plant is a poor seed for growing plants, and a good heirloom seed will yield a greater yield.
To determine the life span of an old seed packet, first look at the date of purchase. This will give you an idea of how long you can keep it. It will also be advisable to save it from being thrown away. If you find an Old Seed packet, you should first make sure that you have a good storage location. Warm and dry conditions are the most effective for storing seeds. If you find that your Old Seed packet is damp or shows signs of mold or fungus, discard it immediately.

The best time to store Old Seed is before the spring when you need to use them. They will germinate better if they are stored properly. Generally, if the seed packet is not stamped with a date, it is discarded. Alternatively, you can check the condition of the seeds in the packet and see whether they are still alive. Generally, seeds can keep for three years, and even more. If you can find an Old Seed that is only 10 to 20 percent older, it is fine to plant it.
