Fertilising a Phlox subulata 'White Delight'
For optimal growth and a profusion of pristine white blooms, it is important to fertilize Phlox subulata 'White Delight' annually. Early spring is the ideal time, just as the new growth begins to emerge. A balanced, slow-release granular fertilizer is recommended, carefully worked into the soil around the base of the plant. This type of fertilizer ensures a steady supply of nutrients throughout the growing season, supporting the evergreen foliage and the plant's creeping growth habit.
Since this species is evergreen and maintains its foliage year-round, the additional nutrients assist in preserving the vibrant green color even during the colder months. Over-fertilizing should be avoided to prevent excessive growth that could compromise the plant's natural compact, cushioned shape and the density of its spring floral display.
