Fertilising a Campanula poscharskyana
To ensure the Campanula poscharskyana thrives and displays its characteristic vibrant blue flowers, a regular feeding schedule is beneficial. Begin fertilizing in early spring to kick-start the growing season. A balanced, slow-release fertilizer applied at this time will support the lush, green foliage and the onset of blooms. A second application should be made after the initial flush of flowers has subsided, usually around midsummer, to promote continued flowering and robust growth.
It's important to follow the recommended dosage on the fertilizer packaging to prevent overfeeding, which can lead to excessive foliage at the expense of blooms. Always water the plant thoroughly after applying fertilizer to assist with nutrient absorption and to minimize the risk of root burn. With proper feeding, this perennial will reward you with its delightful cascade of star-shaped blossoms throughout the flowering months.
