Soaking Castor Beans


An easy way to reduce your castor beans' germination time is to soak them in water before sowing them. But take care when handling the beans. Castor beans are quite poisonous, and in some individuals even inhaling any loosened dust can cause an allergic reaction. If you have never handled castor beans before, wear a face mask when you handle the beans. Keep children and animals away from the beans to avoid accidental ingestion.

Step 1

Remove any foreign material, attached hulls or damaged beans.

Step 2

Add the castor beans to a bowl of water. Leave them to soak for 24 hours.

Step 3

Remove the castor beans from the water. Pat them dry with a paper towel. Plant them immediately.
