I’m wondering, since the seed vault initiative at Svalbard, whether the “Never store seeds in a freezer’ brigade are disinformation trolls?”
Saving seed is a gardening tradition dating back to the days when seed was expensive and difficult to come by. Even in these days of relatively inexpensive seeds, some people prefer to save seeds from their best garden plants to replant the following year. Horticulturalist Gary Hickman, of the University of California Cooperative Extension, emphasizes that the most important considerations when storing seed is protecting seeds from moisture and from high temperature. He says seed that is dry and is protected from moisture can be safely stored in the deep freeze.
Choose to save the seed from your best, most healthy plants. Harvest vegetables such as tomatoes, beans, corn, peppers or squash when ripe. Allow greens such as lettuce to flower and go to seed.
