Anybody who grows vegetables can benefit by harvesting and storing seeds from their own crop. Over the years, not only will you save money, but the seeds will learn to thrive in your particular soil, which in turn results in higher quality vegetables. If you want to store seeds for a long period of time, one effective option is to freeze them. The process of freezing seeds is as easy as it sounds and requires very little preparation work.
Lay the seeds out on a baking sheet, and let them dry for three days in the sun. If the seeds are already dry, you can skip this step.
Pour the seeds into a paper envelope. If you have different types of vegetable seeds, be sure to separate them into different envelopes.
Write the name of the seeds and current date on each envelope with a marker.
Put the envelopes in a resealable plastic bag. Squeeze out as much air as you can from the bag and seal it.
Put the bag in the freezer until you are ready to use the seeds.
