Fertilising a Centaurea dealbata
To support the vigorous growth and delightful fragrance of Centaurea dealbata, a balanced approach to fertilization is essential. It is advisable to apply a general-purpose fertilizer in early spring to kickstart the growing season, ensuring that the soil is well-enriched as the plant begins to flourish. As the blooming period approaches, providing a supplemental feed can be beneficial, particularly if the soil is less fertile or if the plant's foliage appears lackluster.
To maintain the health and vitality of Centaurea dealbata, additional fertilizing during the summer months can be advantageous, especially after the first flush of flowers. This will help in sustaining the bushy, spreading growth habit and encourage a continual display of the plant's striking purple and pink blooms through the summer. Regular feeding, coupled with adequate watering, will ensure that Centaurea dealbata remains a vibrant and aromatic presence in any border or group planting arrangement.
