Fertilising a Campanula persicifolia 'Alba'
For robust growth and a profusion of its charming white blooms, Campanula persicifolia 'Alba' benefits from being fertilized at the onset of the growing season. A balanced, slow-release fertilizer applied in early spring will provide the sustained nutrition necessary for this species' development. It is crucial to ensure that the applied fertilizer is well integrated into the soil to prevent root burn and to facilitate optimal nutrient absorption.
As this plant displays an upright growth habit and can reach a height of up to 80 cm, consistent feeding will support both its vertical development and floral production. A second application of fertilizer can be beneficial in midsummer to maintain its vigor and enhance the quality of the foliage and flowers throughout the blooming period, which extends from June to August.
