Fertilising a Dianthus deltoides 'Flashing Light'
To ensure the vigorous vitality and optimal blooming of Dianthus deltoides 'Flashing Light', a balanced fertilization regimen is crucial. It is recommended to fertilize this species in early spring, as new growth emerges, and again at the onset of the flowering period in late spring or early summer. A slow-release, balanced granular fertilizer is suitable for this evergreen perennial, as it provides a steady supply of nutrients throughout the growing season.
Apply the fertilizer around the base of the plant, taking care to avoid direct contact with the foliage to prevent any potential damage. Watering the plant after fertilizing will help to distribute the nutrients into the soil, allowing the roots to absorb them more effectively. This practice will support the plant's creeping growth habit and contribute to a lush, vibrant display of red blooms throughout the summer months.
