Growing Phlox

Phlox paniculata or summer phlox or border phlox - so many names for this wonderfully performing perennial. This old fashioned beauty will remind you of your grandmother's garden. Here's how simple it is to grow:
Choose a well drained soil rich in compost. Mulch around roots every spring.
Be sure to allow air circulation around the plant to deter powdery mildew. To help build circulation, plant about 1 foot apart. If the plant becomes too thick with stems, thin in the spring by cutting out one third of the stem mass.
Divide plants every 3 or 4 years to encourage stronger growth.
Place in full sun. If that's not possible, then the phlox should get at least 4-6 hours of sunlight per day.

    A garden staple! Some cultivars are significantly less prone to powdery mildew than others in my experience. I never saw a lick of it on "David," for example, which is probably the white one in your bottom photo.
    • @Douglas Hunt That's good to know, Douglas. Thanks. I wish I knew the varieties of my phlox, but the white one was here and the others were splits from friends who didn't know their names.
