Is it all right to put rhubarb leaves in the composter.
I was always told by my father that they would poison the compost. Is this true?

Although people should not eat the leaves, the reason being their relatively high oxalic acid content, this does not pose a hazard to the compost. I have put small amounts of rhubarb leaves at a time into my compost with no problems. There is no reason I can think of why it would be a bad idea to add them as long as you are not adding them in such a quantity of fresh green material that the materials become overall too wet and high in nitrogen and consequently causing the mix to go out of balance.
