Saving your own garden seed is an inexpensive way to plant your favorite varieties of vegetables each year. Saving pumpkin seeds is a simple endeavor, as the seeds are large and the fruit is usually picked once the seeds are fully mature for eating anyway, leading to no waste of fruit when harvesting for seed stock. Properly preparing the seeds for storage as well as proper storage procedures ensures the pumpkin seeds survive until it is time to replant them in spring.
Harvest pumpkins when the rind has reached its mature color and the fruit is firm. Leave pumpkins to further ripen in a cool, dry place for up to four weeks after harvest, if desired.
Cut the top of the pumpkin off with a sharp knife. Cut small pie pumpkin varieties in half.
Scoop the pulp and seeds out of the shell with a spoon or your hands. Separate the seeds from the pulp by hand.
Place the seeds in a colander. Rinse off remaining pulp under running water.
Spread the pumpkin seeds out in a single layer on a sheet of newspaper. Set in a warm, dry room for two weeks or until the pumpkin seeds are completely dry.
Label a jar or envelope with the pumpkin variety and the year harvested. Place the saved seeds in the jar and store in a cool, dry place until you are ready to plant in spring.
