Hi all,
I cut a dozen rhubarb stalks from my yard the other day, and
proceeded to put the leaves in the compost pile. I know the leaves are
posionous, but does anybody know if they will break down okay? I
really didn't think about it at the time- duh!!

They will break down just fine. The poison is not very dangerous and it is
not very persistent. It is oxalate an organic compound which will go into
the mix and come out as something else and/or at least be greatly diluted.
