Opening Act Ultrapink Phlox Care
This easy to grow perennial will grow in soil with a pH within normal garden ranges. It has average watering and soil fertility requirements. It will perform best in moist, well-drained soil and full sun. Fertilize in the spring with a balanced fertilizer or top dress with compost.
Deadheading is not necessary for continuous bloom, but you can cut the plant back by a third in early summer if you want to delay the bloom period in exchange for a bushier plant. Cut the stems back to the ground after your first killing frost. Discard the foliage if there is any sign of powdery mildew on it.
Opening Act Ultrapink Phlox Spacing
Space this medium height phlox 32 to 36 inches apart. Even though it is mildew resistant, it’s best not to crowd this plant. Room for good air circulation helps reduce the threat of a mildew infection.
