2012 Peony Disease Bud Blast

I've had several peonies with buds that weren't able to develop. I think it has to do with the weather, which has been a bit weird this spring. It was really rainy right before the foliage and buds started to develop, and then it was dry for quite while they were growing. I could tell that there was some bud blast and blight on some of the foliage, but I think the succeeding dry period prevented it from developing further (which could have been much worse). Established plants seemed to make out with only a bit of brown near the edges of leaves or a rotten stem or perhaps a bud or two that succumbed to the disease. However some peonies that I ordered just last fall were really taken over by blight and disease. I planted these roots in brand new locations. So no other peonies had been planted there. It was previously just organically maintained lawn. It makes me wonder if the peonies had been sprayed with fungicides by the growers to keep the diseases at bay. Then perhaps when they were planted here in my garden, the plants succumbed to the disease that had been previously kept in check by chemicals. Maybe the peonies will come back next year or maybe they will die. I have had both outcomes with new plants from reputable vendors. Let's hope for the best...
Established Plant - Peony 'Do Tell'

Established Plant - Peony 'Scarlet O'Hara'

Newly Planted - Peony 'Carina'
