Fertilising a Astilbe × arendsii 'Fanal'
To ensure robust growth and vibrant blooms for Astilbe × arendsii 'Fanal', a regular fertilization schedule is crucial. Fertilize once in early spring to kickstart growth, and again in late spring just before blooming begins. Use a balanced, slow-release fertilizer to provide a steady supply of nutrients. Apply the granules according to the package instructions, ensuring they are spread evenly around the base of the plants without coming into direct contact with the foliage to prevent burn.
This species thrives with nutrients that encourage the development of lush, green foliage and the striking red flowers that characterize summer displays. Adequate fertilization, combined with its preferred growing conditions of well-drained soil and partial to full shade, will result in a healthy, flourishing display throughout its blooming season.
