Plant Spring Hot Pink Moss Phlox in well-drained soil with full sun exposure. Space plants about 12-18 inches apart. Water regularly during the first growing season to establish a deep root system. Once established, water only during extended dry periods. Fertilize lightly in early spring with a balanced fertilizer. Prune after flowering to maintain shape and encourage dense growth. Divide clumps every 2-3 years in early spring or fall to prevent overcrowding.
