Q.Melon seed saving
I have this Christmas melon that was picked in October but sitting on my counter all this time. It was starting to liquefy on the bottom and it has furry white mold over most of it now. It is rotting, but could the seeds be saved safely?
Yes, you can save the seeds.

Keep in mind that since the Christmas Melon is a hybrid, the seeds will likely not be identical to the parent plant.
