Care & Maintenance Tips
Planting:
Plant in full sun to part sun in fertile, well-drained soil. Flame® White Improved performs best with good air circulation and consistent soil moisture. Avoid overcrowding plants, as proper spacing helps reduce the risk of powdery mildew.
Watering:
Water regularly during the first growing season to establish a strong root system. Once established, maintain moderate soil moisture, particularly during periods of summer heat and active flowering. Water at the base of the plant when possible to keep foliage dry.
Fertilizing:
Apply a balanced slow-release fertilizer in early spring as new growth begins. Adding compost or other organic matter can help improve soil fertility and moisture retention.
Pruning:
Remove spent flower clusters throughout summer to encourage additional blooming and maintain a tidy appearance. After frost, cut stems back near ground level or leave them standing until early spring before removing old growth.
Disease Prevention:
Garden phlox can be susceptible to powdery mildew, particularly in humid conditions. Provide adequate spacing, good air circulation, and avoid prolonged overhead watering to help maintain healthy foliage.
