Question: Is there a cultivar of phlox that is mildew resistant? The leaves of my phlox get mildew on them every year.
Answer: Phlox is known for its susceptibility to powdery mildew. Here are a few that are supposed to be resistant: 'David,' 'Eva Cullum,' 'Bright Eyes,' and 'Franz Schubert.' Don't crowd phlox as good air circulation helps prevent mildew. Also, clean up all plant material and discard it at the end of the season, and rotate where you plant species every year to help prevent build-up over time. Good luck!
