Ragan's Reviews > Seed to Seed: Seed Saving and Growing Techniques for Vegetable Gardeners

I was just reading recently that most of the seeds you buy though the store and though a catalog are genetically engineered to not produce viable seeds. Check out seedsavers.org for plants that will produce viable seeds. This is an important thing to know about, especially if our food economy collapses and we must find ways to feed ourselves.
