I have been putting rhubarb leaves into my composter, and my neighbor tells me that this is bad. I know that the leaves are not to be eaten, but thought that any danger would pass in the decomposition of them. What's right?
I found a reference to Rhubarb leaf composting and it sounds like its fine. quote from the book; " Rhubarb leaves contain toxic quantities of oxalic acid. Don't eat them: Trim them off the harvested stocks and compost them." from: the organic gardener's handbook of natural insect and disease control. Rodale press.
This is an old Danish folk lore based on the assumption that rhubarb leaves are toxic and they will stop the composting process.
