Saving seeds is nothing new -- our ancestors did it as a matter of survival. The trick is to store those seeds securely, so they’re still viable next year. Whether you’re collecting seeds from your garden in fall or salvaging the leftovers from a seed packet you bought in spring, here’s what to keep in mind:
First, make sure the seeds are dry. This is especially important if you’re collecting seeds in the morning, before the dew has evaporated. It likely won’t be a concern if you’re storing seed packets.
Take the seeds and put them in an envelope marked with the date as well as the plant’s name and cultivar, if known.
Seal the envelope and store it in a glass jar filled with one inch of baking soda to absorb any moisture in the air. Cap the jar and place it in a cool, dark, and dry part of the house.
That’s it. When you’re ready to use the seeds, just open the jar and remove the envelope. Bear in mind, though, that seed viability diminishes over time, so you’ll need to sow more seed than usual to get the same amount of germination.
