Fertilising a Salvia nemorosa 'Ostfriesland'
To ensure the Salvia nemorosa 'Ostfriesland' thrives and displays its vibrant purple blooms, an appropriate feeding schedule is essential. Fertilize this species in the early spring as new growth appears, using a balanced, slow-release fertilizer to promote vigorous foliage and flower development. A second application of fertilizer can be beneficial in midsummer, just before the onset of the flowering period, to support the plant's extended blooming season through the summer months.
It is important to follow the recommended dosage on the fertilizer package to prevent overfeeding, which can lead to lush foliage at the expense of flowers. Water the plant thoroughly after applying fertilizer to help distribute the nutrients into the soil. Regular fertilization, paired with proper care, will keep this clump-forming perennial healthy and full of blooms each season.
