Q.Good Day. My Question Is How Do I Treat My Castor Bean For Planting. Note: I Have Castor Plants That Yield Fruits But Each Time I
want to plant a new castor I have to go to some people selling the “plantatable seeds”. THEY SAID IF WE PLANT THE CASTOR BEAN GO TTEN FROM OUR CASTOR PLANT WITHOUT GIVING IT TO SOME PEOPLE WHO THEY SAID WORK ON THE SEEDS BEFORE WE PLANT, IT WILL GROW BUT GROW TALL AND NOT YIED FRUIT. Thus we buy the seed to plant despite we having it. For instance, I have castor plantation, and I have castor seed harvested from it. But if I want to plant another farm, I cannot plant the seed from my farm because they said it wont do well. So Ihave to go and buy another seed from seed seller.

I would ask for more information than "plantable seeds." If you are growing the castor bean plants for a specific purpose, such as for castor oil, then you may be planting hybrid seeds. Those seeds produced would not be usable because they would not have the same characteristics as the hybrid. You may get characteristics from only one parent. The phrase often used is "it will not grow true to seed."
So, I would find out if you are planting with hybrid seeds. You may have an agricultural source of information you use that you also can consult.
