I dug up and old peony early on a noticed lots of black, slimey gook on parts of it. I googled and found it was rot..kind of smelled like that too. None of the new roots are anywhere close to the rot on my dug up peony, but with all the rain this year, I don't want to take too much of a chance. I think cutting off as much as I can will probably work...just want a little reassurance.
