Peonies and iris
I have a bed of bearded iris that I planted when we moved in 2 years ago this july coming. The previous owner used to have peonies in there but took them with her because they were her grandmothers. Last year I noticed some peony shoots coming through around the irises, they weren't really a problem, but this year they are getting quite big and today I noticed they are in flower. I would like to separate the peonies from the iris'. I am assuming it will be best to do this in autumn, am I right?
