Hi there!
I've read and see many things about how to save squash's seeds in general.
But for Butternut I have seen one time that person saying that once they were washed, you should let them soak in water for about a day, and the one that will sink in the bottom are the one you can plant, the others you can discard. Then I never saw any other person talked about this, is that true ?
Is there a "general" rule for squash of all sorts ? Because it seems "too easy" to think that you can always save ALL seeds from a squash ?
Thanks a lot
