Fertilising a Dianthus deltoides 'Brilliant'
To ensure the vibrant red and pink hues of Dianthus deltoides 'Brilliant' are expressed to their fullest and the plant maintains its lush, silver-grey foliage, adequate fertilization is crucial. A balanced, slow-release fertilizer applied once at the beginning of the growing season in spring will suffice. This will support the species' creeping, widespread growth habit and sustain it through its flowering period from June to August.
When fertilizing, be cautious to distribute the granules evenly around the base of the plant, avoiding contact with the leaves to prevent any potential damage. Water the area gently after application to help the nutrients penetrate the soil. This practice will bolster the plant's health and vigor, promoting robust growth and a profusion of blooms throughout the summer months.
