To freeze or not to freeze, that is the question. Well, it’s the question for a number of people who store seeds, anyway! There seems to be some controversy on this subject, so I thought it would be a good idea to talk about it. After researching a number of different viewpoints on this topic, I’ve come to a few conclusions.
Seeds, much like the food that they produce under the right growing conditions, are susceptible to certain things, including moisture, light and warm temperatures. Fresh food will go bad quickly when exposed to any of those elements. With seeds, the process is slower, but they will definitely suffer the same effects. But if seeds are frozen, their DNA will stay intact for a long time. Those who claim that freezing seeds is a bad idea point to the seed’s natural moisture that will freeze, expand and crack the seed. But if the seeds are dried first, it’s no longer a problem. And last time I checked, nature does a pretty good job of freezing seeds in the winter, thawing them in the summer and then providing the warmth, light and water they need to fulfill their purpose.
I got a lot out of this article called “Storing Your Seeds for the Long-Term…in the Freezer.”
The author acknowledges that short-term storage (one or two years) may only require refrigeration, but insists that your seeds will benefit from a freezer if they are designed to be used several years down the line at the soonest.
What has been your experience with long-term storage of seeds? Have you kept them in the refrigerator or the freezer or somewhere else? How have your frozen seeds compared to the non-frozen ones in terms of performance after they were planted? Let me know what’s worked for you and what hasn’t.
