Pests or Diseases: Phlox is not always an easy plant to grow. Powdery mildew and root rot can be serious problems. Spider mites and plant bugs can also be a problem, particularly in hot, dry conditions.
Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly.
Grow in moderately fertile, medium wet, well-drained soil in full sun to light shade. Best in full sun. Prefers rich, moist, organic soils. Needs good air circulation (space well and thin out stems as needed) to help combat potential powdery mildew problems. Intolerant of drought and needs to be watered in dry spells. Avoid overhead watering, however. Appreciates a summer mulch which helps keep the root zone cool. Remove faded flower panicles to prolong bloom period and to prevent unwanted self-seeding.
