Homeowner Growing & Maintenance Tips:

Phlox paniculata is unequaled for showy blooms over a long period throughout the summer. Though they are some of the most popular perennials available, they do require some maintenance to sustain their health and vigor.

Tall Garden Phlox grows best in rich, moist soil in full sun. It will thrive with bi-monthly fertilizing and consistant moisture levels. Overhead watering should be avoided since some varieties of phlox are susceptible to powdery mildew. This can be avoided or diminished by providing ample air circulation around the plants and by thinning them out periodically. Deadheading will prolong bloom time and prevent self-seeding.
