For winter storage, should Castor Bean seeds be refrigerated
or frozen? Thanks, Dale
I've had good luck with taking the beans out of the pod, air drying them, and storing them in a glass jar. I haven't tried refrigerating or freezing, so I can't comment on that.
Have a good day!
I've had no problem overwintering them at room temperature. For long term storage (2 or more years) refrigeration may help.
Please remember that all parts of the castor bean plant are poisonous and store accordingly.-Sandy
They don't need cold stratification, so I would be reluctant to refrigerate unless in an airtight container. Frost free refrigerators dry exposed seeds quickly.
I had some seeds I had kept for 5 or more years in a hard cardboard box with a tight lid, in my basement. I gave them to a friend & she had good success with germination.
