Pea seeds are easy to collect and save for re-planting next year. In fact, mother nature will do most of the work if you let her. The first step is make sure you are saving pea seeds from a well-established heirloom variety so you'll have the best chances at success. There are quite a few heirloom pea varieties available to choose from. For regular garden peas, Thomas Laxton and Lincoln are both good heirloom varieties. For a sugar pea variety, Mammoth Melting Sugar is a good heirloom choice.
For best results, you want to leave the peas on the plant until they dry
out. The pods will turn brown and brittle and when you shake the pod,
you should be able to hear the hardened seeds rattling around inside.
At this stage, you can go ahead and pick the peas and bring them inside
to dry out a bit more. Remove the pea seeds from the pod and spread the
seeds out on foil or a baking sheet and let them air dry for another
couple of days. Go ahead and inspect them for any signs of mold and
discard any seeds that don't look right. When they are done, you want
the seeds to be hard and shriveled up a bit. Then you can then put the
seeds inside an envelope and store them in a jar in your refrigerator.
Make sure you label the envelope so you know what seeds it contains. If
you are saving lots of different seeds, several envelopes can fit
inside one, quart-sized jar. It's also a good idea to put a tablespoon
of dry rice at the bottom of the jar just to absorb any moisture.
