Growing and Maintenance Tips

Creeping phlox is a versatile, easy to grow groundcover for full sun. Gritty, neutral soils are prefered and good drainage is essential. It's a good idea to shear this plant back and clean up any dead foliage in early summer, just after it's finished blooming. This will produce denser foliage and will encourage it to rebloom. Divisions can be made every few years in summer.
