Yes, now is a good time to be watering your perennials and up until the ground freezes. Though peonies are very hardy in Minnesota it is always good to water them when we aren’t getting rain.
If you have seen any powdery mildew on the leaves you can also prune those off. If they are covered in mildew, they are no longer able to photosynthesize.
