Phlox Paniculata Blue Boy
Plant Phlox paniculata ‘Blue Boy’ in a sunny location to ensure the best flowering and growth. It thrives in well-drained, fertile soil enriched with organic matter. Regular watering is important, particularly during dry spells, to maintain a lush appearance and promote abundant blooming. This perennial is relatively low-maintenance but benefits from periodic deadheading to encourage prolonged flowering and prevent seed formation. Phlox paniculata is susceptible to powdery mildew, so providing good air circulation around the plant can help mitigate this issue. In late autumn or early spring, cutting back the foliage to ground level can help maintain a tidy appearance and promote fresh, healthy growth. Applying mulch around the base can help retain soil moisture and regulate soil temperature, especially in extreme weather conditions.
