Nobody wants to talk to you J----. I would say no, Rhubarb is the only plant we eat which develops poisonous leaves as far as I know, this poison will not transfer to another plant because of it's gene structure.I know they can be poisonous if eaten but what about adding them to my compost pile? Will it harm or contaminate the soil?
TIA!!
