Survival seeds are one of the essential emergency preparation supplies that every family should have. When a survival garden is needed, you will be happy to have invested in such an important item. In exchange for your energy and time, you will want a survival garden that will provide your family with abundant food. Non-GMO, heirloom seed is best. These seeds produce seeds you can save for future harvests. Stocking up on a few packets of GMO seeds is not bad for an emergency back up. You can never have enough seeds. If stored properly, this seed can last much longer than expected expiration.
