I usually harvest my castor bean seed each year but this year they
don't seem to be any good. They didn't pop in the bag over the winter
and when I separated them manually, they floated on top of the water
for more that a day. After two weeks no germination.
I just bought a package of seed at a nursery today. They float on top
or the water too.
My question is: do Castor been seed always go the the bottom right away
or could they still be viable if it takes 24 hours for them to sink?
