Q.Should Joe-Pye Weed be cut down?

Zone Chicago Ill area | Anonymous added on September 27, 2020 | Answered

We like the blooms & wish they lasted longer. We purchased 2 more & they are the same. Should we cut them back in the late fall/early winter? Also there is a powdery look on the leaves as well. Is that a fungus?

It sounds like you have some powdery mildew. Here's an article that will help you understand how to deal with it: https://www.gardeningknowhow.com/plant-problems/disease/powdery-mildew-homemade-and-organic-remedies.htm

You can trim the plant back once it has died off in the late fall, or wait until spring. Here's an article on the care of this plant: https://www.gardeningknowhow.com/ornamental/flowers/joe-pye-weed/growing-joe-pye-weed.htm
