Hi I've got a peony that the flowers turned brown which I know is usually that fungus I can't remember the name of right now but the leaves look OK and usually it affects the leaves? It didn't flower last year as I'd moved it from a container but it happened the year before in the container also. I've removed the brown flowers and sprayed with fungus stop, there are still unopened buds is there any hope for them? Not sure whether to give up with it, all the anticipation of waiting for the buds to grow and open then the flowers die! Is there anything else it could be? Can I prevent it in future by spraying early?
