I have a major vole problem. I would like to grow as many caster bean plants as possible to see if they will help. The caster bean oil is not.
I don't care if they act like an annual. Their roots will still be in the ground and act like a repellent hopefully. I can grind, or chop the limbs and leaves and add to the soil also.
What variety will be best in zone 8a? We just changed from 7a to 8a here. Thank you in advance. I am pretty desperate.
