About my coneflower…

We have a pretty big problem with aphids and powdery mildew on two of our three coneflowers. Since it’s mid-August already, should we cut our losses, cut the coneflowers down now, and use the solutions you provided in your articles to prevent it from happening again next year – or – will the early pruning be detrimental to the long term health of the plants? Thanks so much!!

It is likely the plants will not have any issues with being cut down now. Dispose of the plants so that the insects and Powdery Mildew does not spread.
I myself just did the same cut back in my own garden.
