The Q&A Archives: Growing Tips for Perennial Phlox (Phlox paniculata)

Question: I need help with perennial phlox. I am in zone 4 and need some advice for the best growing conditions. Thanks. Jodi Wendland Windom, MN

Answer: Perennial phlox (Phlox paniculata), a native to eastern U S, thrives on full sun or partial day shade. It likes deep soil that remains moist during hot dry weather but doesn't like sandy soil. It has surface rooting so mulch keeps its root structure moist. Be alert for slugs and be prepared for powdery mildew.
