castor oil for lawn and garden
I saw an article by Bonnie L. Grant that talked about castor oil. I found an oil at Bulk Apothecary that is much less expensive than other sources. Do you know if this is OK? I have read that unscented is less good but rodents mostly use taste and not smell so the scent seems at least partially irrelevant to me. A BA rep. says it's for cosmetic purposes but they may not know about it's other uses. Do you know about this? Thank you, Ron

I have not used it, but I understand it works well if the weekly applications are kept up. I don't know about your specific oil, but go ahead and try it and see if it works, too.
