Soil Type
Water: Spreading phlox thrives in well-drained, moderate moisture soils, requiring weekly watering for optimal health. It prefers consistent moisture without oversaturation and excels outdoors, particularly during its growing season when soil balance is maintained with adequate drainage.
Fertilize: For spreading phlox, use a balanced fertilizer in spring to boost roots and foliage, then switch to high phosphorus during blooming. Fertilize monthly, adhering to product guidelines, while avoiding over-fertilization. Reduce feeding in dormancy and consider diluting fertilizer to half-strength to prevent root burn.
Pruning: Spreading phlox requires pruning to enhance growth and flowering, ideally in early spring or late winter. Remove damaged stems to improve air circulation and prevent overcrowding, promoting vigorous blooms and a tidy look. Consult reliable horticultural sources for pruning best practices.
Propagation: A perennial favorite, spreading phlox is best started through sowing in a well-drained medium suitable for its alpine origins. Light surface coverage aids germination, requiring consistent moisture and sunlight. With patience, gardeners can enjoy a vibrant spread of spreading phlox in their outdoor spaces.
