For the past week or two, I've been noticing large brown spots/blotches on the peony foliage and this morning I went out to check it and noticing some of the leaves have a silver color(is that mold?) I did a lot of internet searches this morning and this is what it describers. It recommended using a fungicide but didn't suggest any specific one..Have you had this happen to any of your peony plants?
I can be partly to blame because as I have been watering with the garden hose, I watered the foliage too just not the soil in the flowerbed. High temperatures 90-104 for past 40 days..Tonight we just received a bad storm that produced not only thunder, lightning and hard winds and rain but hail. Lots of leaves were blown off the trees. The grass should start turning green after the rains we had this week.
Can you recommend a good fungicide or should I cut the entire plant down to the ground before Fall? I don't want to do that unless it is last resort as this peony is special. It was given to me at a plant swap in May and it was healthy when I bought it home here.
