Pinching and Growth Regulators

Soft Pinch when the plant is 3 to 4 inches tall. The lower the plant breaks the better the plant quality. If flowering is desired, allow 10 to 12 weeks after the onset of long days for flowering. 'Shockwave' is grown for foliage as much as flowers and may have a shorter crop time since flowers are unnecessary for sales.

.

Pest and Disease Management

General pest and disease practices as listed in notes.

Watch for aphids, spider mites and whiteflies, scout and treat as needed.

Leaf spots and powdery mildew can be problematic.

The Flame series of Phlox is less mildew susceptible than many that are available.

Grower Tips

-Quart size plants are sold green rather than in flower.

-Good air circulation, high light levels and watering in the morning will help decrease disease incidence.

-Vernalization will increase plant vigor, decrease time to flower and improve uniformity of flowering.

-'Shockwave' can be used as a foliage interest plant in combinations.

-'Shockwave' performs best with fertilization rates between 75 and 100 ppm.
