IF they appear to be in good condition, & not moldy or rotted, I say why not give it a try ??--be sure to dry them out well, so they dont mold in the mean time though. They should/could be kept in the gourd until it rattles, sorta like a maraca. But after they are dry in the gourd,
if you think you should look at them then do the newspaper thing:
Spread the
seeds on a layer of newspaper, and let them dry in a cool place for several weeks. When they are well dried, store them in a tightly sealed jar kept in a cool location. ( like say a refrigerator or a cool garage ) If you take a small cloth bag and fill with Powdered milk , tie it shut and place it in the same jar, it will absorb any extra moisture.
Keep
seeds away from light or Moisture between collecting and planting. This will keep
seeds in a dormant state until you are ready/able to plant
Good luck & keep us informed...
